Masoreus (Aephnidius) ciliatus new species (Mutchler) (PI. 5, fig. 9)
Oblong oval, black, legs, antennae and mouth parts testa- ceous.
Head subquadrate, finely closely punctate ; mandi- bles without setigerous punctures in the scrobes, sides ele- vated; basal joint of antennae with a long bristle at apex; front of labrum slightly curved inwardly (almost straight) margin with setigerous punctures; clypeus with a puncture on each side. Pronotum subquadrate, one-third wider than long, wider than the head, widest at about the middle, api- cal angles narrowly rounded and slightly produced, lateral margin with a setigerous puncture on the apical third and another at thle basal fifth, basal angles broadly rounded, marginal bead extending from the side of the insertion of the head to the scutellar area, a median longitudinal im- pressed line, somewhat well marked, extending from the apex to near the base, with indistinct oblique lines,extend- ing backwards from this median line. Scutellum triangu- lar, apex narrowly rounded. Elytra with humeral angles rounded margins not interrupted, surface (under high

power magnification) with indications of faint strias and appearing as if covered with fine scales giving them a silky appearance, possibly granulate punctate, submargin with setigerous punctures, apical angles rounded. Front tibiae with two elongate spines at upper end of the emargination (the outer one apparently bifid for about two-thirds its length), apical spine somewhat long; joints of the front tarsi shorter than those on the other legs, first joint slightly longer than the next two taken together and about as long as the apical joint, joints two, three and four gradually shorter, hind tarsi with the first joint slightly longer than the apical joint, other joints shorter, claws distinctly but shortly pectinate; hind tibiae, with spines similar to those on the middle tibiae, on the outer side. Length 4.5 mm. Type.
Ensenada, Puerto Rico, June 17 to 19, collected by Dr. F. E. Lutz, on the side hill back of Canary Cottage, under stones, in a field containing numerous cacti. In American Museum of Natural History. One paratype.- Soledad, Cienfuegos, Cuba, October 26, collected by P. J. Darlington. In Museum of Comparative Zoology. Two paratypes.-Cayamas, Cuba, June 6, collected by E. A. Schwarz and Porto Rico, with no definite locality, collected by George N. Wolcott. In United States National Museum. Remarks. This new species resembles Aephnidius (= Masoreus) piceolus Chaudoir, and believing that it might possibly be that species I failed to describe it in the recent paper on "New Species of Carabidee from Puerto Rico" Amer. Mus. Novitates. No. 686. Since these descrip- tions appeared a specimen of this species from Cuba was submitted by Dr. P. J. Darlington to Mr. Ren6 Oberthiir for comparison with the Chaudoir type.
The reply from Mr. Oberthur stated the Cuban specimen was not Chaudoir's species. The West Indian species dif- fers in having the antennae and legs stouter than the true piceolus (although still slender) and probably differs in other ways.
The paratype from Cayamas, Cuba, is somewhat brown- ish black in color, possibly due to being collect~ed before the coloring had fully developed.
