DESCRIPTIONS OF SOME NEW CALLISTINAE
(COLEOPTERA, CARABIDAE) FROM EAST AFRICA1 BY P. BASILEWSKY
Belgian Congo Museum, Tervuren, Belgium
Through the kindness of Dr. P. J. Darlington, Jr. of the Museum of Comparative Zoology at Harvard College, Cam- bridge, Massachusetts, I have been able to study certain Carabidae collected by Mr. Arthur Loveridge during his trips in East Africa. I sincerely thank Dr. Darlington for this opportunity.
In the material I have found three
new forms belonging to the subfamily Callistinae. I here give their descriptions.
Pachydinod,es raffrayi (Chaudoir) darlingtoni sutosp. nov. Length 15-17mm. Differs from the typical form, widely distributed in Tanganyika Territory and the southern part of Kenya Colony, as follows : Size larger ; color lighter green, antennae and legs lighter ferrugineous; form more elongate and slender. Prothorax with sides very distinctly narrowed toward base, widest near middle of length; posterior angles more rounded; base nearly same width as anterior margin; punctation of upper side the same. Elytra more ovate, dis- tinctly widened behind the shoulders ; latter less prominent; greatest widthof elytra near middle of length ; striae strong- ly impressed, punctured (lightly) only in anterior half, intervals mpre convex, especially in basal part. Lower side similar, but tneta'-episterna longer and with several large punctures. The t*o specimens seen have no trace of a pre- apical yellow spot.

19511 BasilewskyÌÔEas African Callistir~ae 43 The differences given above completely change the ap- pearance of the beetle as compared with typical raffrayi. It is possible that the new form is in fact a distinct species ; but, as I have seen only two females, I prefer to wait for more material before deciding the degree of relationship more precisely.
Epomis loveridgei n. sp.
Length 18.5; greatest width 7.2 mm. Upper side dark violaceous, very shining ; scutellum black ; lower side black, without metallic reflections ; legs ferrugineous, femora very dark, nearly black ; antennae brown.
Head wide and short; eyes large, moderately prominent, temples very short, almost enclosed by the anterior margin of prothorax; upper surface smooth at middle, with some large scattered punctures posteriorly and laterally ; labrum small, with anterior margin straight; palpi elongate, last segment ( s ) of maxillary ones straight at tip, last segment of labial ones faintly enlarged, next to last segment with several setae; maxillary ones pubescent; antennae with 4th segment pubescent, 3rd a little longer than 4th. Prothorax large, faintly convex, slightly cordiform ; an- terior angles rounded; sides gently rounded in first two- thirds, then narrowed and sinuate; posterior angles right; base straight, not margined, nearly same width as anterior margin ; greatest width slightly before middle; median line fine and short but well marked; lateral troughs narrow; in- ner basal foveae rather deep, fairly long, nearly linear ; up- per surface flat, with faint longitudinal median depression in which is the median line; surface covered with irregu- larly spaced large punctures ; anterior lateral setae missing, the posterior ones in the lateral troughs distinctly before the angles.
Elytra sub-ovate, faintly convex, with greatest width near middle ; basal margin annulate at shoulder ; apical trunca- tion oblique and rounded ; shoulders faintly developed ; striae strongly impressed, well punctured, nearly reaching base, the scutellar one long and straight; intervals strongly con- vex, very shining, without microsculpture, punctate only at sides against the striae; 8th interval covered with spaced

punctures, but 9th entirely punctured-shagreened ; seven dorsal punctures on the 3rd interval.
Lower side shining, nearly glabrous ; prosternal process not margined, hastate, with a tuft of setae at tip; pro- episterna with some large punctures anteriorly, near the internal suture; meso-episterna smooth; meta-episterna as wide as long, with numerous punctures; abdomen punctured- shagreened at sides ; aedeagus as figured (Fig. 1).
Figure 1. Epomis loveridgei, n. sp., aedeagus. Figure 2. Chlaenius (Platychlaenius) uzungwensis, n. sp., aedeagus. TANGANYIKA TERRITORY: Bagil, Uluguru Mountains (A. Loveridge, IX. 1926). Holotype $ in the Museum of Com- parative Zoology (Type No. 28,234). The type is unique. This new and remarkable species is allied to Epomis vio- laceipennis Chaud., of West Africa and the Belgian Congo, by the smooth and convex intervals punctate only against the striae, by the same convexity of body, by the prothorax little widened anteriorly, and by the absence of a yellow elytral margin. It differs from violaceipennis in color of head and prothorax, in elytra being more shining, and in other ways. The prothorax of the new species is more trans- verse, distinctly cordiform, with sides strongly sinuate pos- teriorly, and with stronger but more widely spaced punc-

10511 Basilewsky - East African Callistinas 45 tures. The elytra are more distinctly ovoid in shape, with shoulders more obliterated and interstices more convex, more shining, and without microsculpture. The lower side has less, but coarser, punetation; the prosternal process is less acute at tip; the meso-episterna are smooth; and the meta-episterna are shorter, not longer, than wide. Finally, the last segment of the labial palpi is less dilated than in any other form of the genus, that of the maxillary palpi being simple. The aedeagus is different too. Chlaenius (Platychlaenius) uzungwensis n. ap. Length 13 mm. Head and prothorax reddish brown, the latter a little lighter ; elytra black, scutellum reddish ; lower side of head and prosternum reddish brown, other sterna and abdomen black ; legs and antennae dark ferrugineous. Head long, with very fine punetation, chiefly on disk, nearly obliterated on vertex; eyes large and prominent, temples short, faintly narrowed posteriorly; anterior mar- gin of labrum barely concave ; antennae long, barely exceed- ing basal third of elytra, 3rd segment much longer than 4th. Prothorax nearly as long as wide, faintly convex; an- terior margin weakly emarginate; anterior angles prom- inent, broadly rounded at tips; sides gently rounded, not more narrowed posteriorly; greatest width a little before middle; posterior angles blunt, widely rounded at tips; base faintly concave, as wide as anterior margin, not emarginate; median line fine, superficial, reaching neither anterior mar- gin nor base; marginal gutters strongly widened posteriorly where sides are broadly explanate and slightly elevated; basal foveae very broad; upper surface with roundish, rather large but not very deep punctures, very numerous at sides especially near posterior angles, more widely spaced on disk; each puncture with a long, yellowish white seta; anterior lateral setae missing-, posterior ones before angles. Elytra sub-ovate, weakly convex; greatest width behind middle ; shoulders rounded ; apical truncation oblique, indis- tinctly sinuate; striae fine but rather deep, not very dis- tinctly punctured, the seutellar one long; intervals weakly

convex, with reticular microsculpture plain under strong magnification, and covered with rather large, rounded, not very deep punctures from which rise long setae, longer at the apical declivity than elsewhere.
Lower side with relatively reduced punctation and pubes- cence; prosternal process rounded at tip, weakly margined, punctured and pubescent ; pro-episterna nearly smooth, with some rather faint punctures near anterior margin; meta- episterna slightly elongate, narrowed posteriorly, strongly punctate, without external groove ; abdomen punctate and pubescent at sides, nearly smooth at middle. Legs long; protibiae of male without tooth near base; upper side of tarsi glabrous; 5th tarsal segment with a double row of spines; aedeagus as figured (Fig. 2). TANGANYIKA TERRITORY : Uzungwe Mountains, Dabaga (A. Loveridge, 4. XII. 1929). Holotype 8 in the Museum of Comparative Zoology (Type No. 28,416). The type is unique. This is a very distinct species, sharply set off by its colora- tion. I place it, provisionally at least, in subgenus Platychlae- nius Jeannel, because of its nearly smooth pro-episterna, but it is strongly differentiated from the other forms of this group by characters given above. The sculpture of the elytral intervals is not granular as it is in most species of Platychlaenius.
