West Indian Carabidse
THREE WEST INDIAN CARABIDE IN FLORIDA
Museum of Comparative Zoology, Cambridge, Mass. Oxydrepanus rufus (Putz.) : Of this common Cuban species I took a small series at Homestead, near the south- ern tip of the mainland of Florida, in June, 1929. They were in floating vegetation in pools, the usual habitat of species of this genus. 0. rufus is plain rufous, shaped like a Clivina but small as a Dyschirius, 3 mm. or less in length. From both the genera mentioned it differs in having the tips of the apical segments of both pairs of palpi finely produced.
Pseuclaptinus (Thalpius) cubanus (Chd.) : one specimen, also from Homestead, June, 1929, was taken in trash be- side a flooded pool. It has been compared with a series from Cuba one of which in turn has been compared with Chaudoir's type by Mr. Ren6 Oberthur, in whose collection the type now is. The species is easily known by the very dull surface, caused by the fine, very dense punctuation. Selenophom discopunctatus Dej. (chokoloskei Leng) : I have several specimens of this species from Dunedin, Florida, from Mr. W. S. Blatchley. Leng's types were from Chokoloskee and Everglade, Florida. My specimens answer Leng's description perfectly, and at the same time are indistinguishable from our large series of the common discopunctatus, which ranges over all the West Indies and much of South America.
MEGACEPHALA (TETRACHA) AFFINIS ANGUSTATA CHEV. ( COLEOPTERA : CICINDELIDLE)
NORTH OF MEXICO
Of this species, not before recorded from the United States, I took four specimens at Brownsville, Texas, June 11 to 16, 1933. They were under street lights at night along the river just above the town, running with numer-

ous specimens of Tetracha carolina (L.) . My identification has been confirmed by Dr. Walther Horn. T. angusta~ta is similar to carolina, but is obviously more slender, a little less shining, lacks the rosy color at the base of the sutural region, and has the pale apical lunules of the elytra nar- rower, not distinctly expanded anteriorly. The subspecies has been known previously from Mexico to Costa Rica; the species affinis Dej. as a whole ranges to the Argentine. P. J. DARLINGTON, JR.
Some twenty years ago in collecting I noted that certain fairly common species of Priocnemis were known only from females and that various species of the Agenia group were known only from males. I have never found any mating, but from field observations decided that Agenia pulchrina Cress. must be the male of Priocnemis nebulosus Dahlb. In talking with Mr. Rohwer about it and looking over the collection we concluded that A. dakota Cress. was the male of Priocnemis fulgifrous Cress. In recent years I have placed the common Agenia iridipennis Cress. as the male of the equally common Priocnemis pompilus Cress., and that the male of Priocnemis fortis Cress. is Agenia nigri- pilosa Cress. There are still some Priocnemis and Agenia unmatched. This makes it necessary to overlook the pres- ence and absence of tibial teeth as separating the two groups. It, however, is not surprising, as there is much variation in size of the teeth in those males of Priocnemis which have teeth; in some cases very small. Moreover in Pepsis and in Hemipepsis there is often a sexual difference in tibial armature.

This genus is not listed in Johnson's New England Dip- tera nor in the New York State List. It was described by Osten Sacken from Central Missouri.
Last summer I took
two specimens of M. bulbosa 0. S. at Holliston, Mass., on the flowers of yarrow, 17 July.
