90 THOS. L. CASEY. 



Founded on a specimen in the» cabinet of Dr. LeConte, where it was 

 labeled alternans. Crotch, in manuscript notes, said it was rather /em;- 

 gineus. It cannot, in my opinion, be either, as in both these species the 

 posterior angles of the prothorax are always prominent and well devel- 

 oped. It seems to resemble more closely the European «/er, in which, 

 according to Sturm, the posterior angles are " stimipf" but not having 

 any specimen of the latter for examination this cannot be stated positively. 



15. li. quadratus n. sp. — Form very moderately elongated; depressed. 

 Surface punctured as in punctatun ; nearly free from pubescence. Body, legs and 

 antennae dark testaceous; integuments dense. Head sub-quadrate; anterior an- 

 gles of epistoma right ; excavation in front of antennae clearly defined, rounded 

 and deep ; elevated margin distinct ; eyes large, very near the posterior angles, and 

 rather coarsely granulated. Prothorax sub-quadrate, very little wider than head, 

 broader than long, hardly narrowed behind; sides very slightly arcuate , lateral 

 striae double, both well developed; anterior angles acute, posterior right. Elytra 

 one-third as long again as the head and prothorax together, a little wider than the 

 latter; entire with the exception of the extreme tip of the fifth ventral segment, 

 which is left exposed; strongly bordered and striate; evenly rounded behind; 

 sides parallel and arcuate ; seutellum evenly rounded behind, short and transverse. 

 Fifth abdominal segment nearly twice as long as the fourth. Antennae about one- 

 half as long as the body, sparsely pubescent, otherwise as in puvctatus ^ , except 

 that the first joint is shorter and more robust than in that species. Length 1.7 mm.

This species resembles ^wnc^a^Ms 9 , but differs from that species most 

 notably in the epistoma. 



16. li. cephalotes Lee. — Form moderately elongated ; depressed. Surface 

 shining. Punctures of head coarse, those near the» middle section so large as to 

 constitute pits, decreasing in size and closeness anteriorly and posteriorly; punc- 

 tures of prothorax much finer, with about the same degree of approximation ; 

 elytra striate, striae punctured ; entire surface covered very sparsely with exceed- 

 ingly minute, erect setae, those on head and prothorax apparently belonging to 

 the punctures, those on the elytra arranged in rows. Color black, a longitudinal 

 area occupying the entire interior of each elytron is a pale testaceous ; legs and 

 antennae dark testaceous. Head very large, quadrate ; labrum emarginate ; man- 

 dibles large, arcuate and prominent ; eyes very small, situated on the sides before 

 the middle ; there is a deep elongated pit in the surface of the head near the base 

 of each antenna. Prothorax of same width as head, broader than long, narrowed 

 behind, much smaller than head, narrowly bordered ; sides nearly straight; an- 

 terior and posterior angles well marked; lateral striae well developed, and not 

 attaining the anterior margin. Elytra equal in length to head and prothorax 

 together, slightly narrower than the latter, evenly rounded behind and entire; 

 sides parallel. Seutellum sub-triangular, and rather large. First abdominal seg- 

 ment nearly twice as long as the second, last four equal in length. Antennae 

 equal in length to the elytra; first joint very moderate, oval ; joints two to eight 

 moniliform, ninth abruptly larger and flattened, last joint more elongated, nar- 

 rowed very slightly, flattened and fusiform. Length 2.4 — 2.6 mm.
