Lyclus slrialus, Melsh: Catal. 178. 



canaliculatus, " " 



Dull reddish-brown : head roughly punctured, yellowish pubescent : eyes black: 

 thorax subquadrate, slightly narrowed behind, with the sides rectilinear to near 

 the apex ; punctured like the bead, golden pubescent, with a wide glabrous in- 

 dentation on the disk : elytra cylindric, frequently paler than the thorax, and 

 sometimes with the disk darker ; obsoletely punctate striate, the interstices yel- 

 lowish pubescent : antennae and feet colored as the elytra: postpectus brown, 

 shining : antepectus and venter reddish-brown. 



2.' ;L. axillaris. Fuscous, or reddish-brown, pubescent ; elytra with a testa- 

 ceous humeral spot. — H 1. long. Pennsylvania. 



Lyctus axillarus, Melsh. Catal. 179. 



fuscus, " " " 



Reddish-brown, or fuscous : head and thorax as in the preceding, the latter, 

 however, is almost quadrate or hardly narrowed behind : elytra sculptured and 

 clothed as in the preceding; humeral tubercle obsoletely testaceoas: antennse, 

 feet and beneath, as in the preceding. This species may probably prove to be 

 tho male of the preceding one. 



L/EMOPHLOErs. Dejean. 



L. fasciatus. Testaceous, glabrous: elytra fuscous, each with a testaceous 

 spot and four strise. — 1 J — 2£ 1. long, £ — 1 1. wide. Pennsylvania. Not rare. 



Cucujus fasciatus, Melsh. Catal. 



Flat, testaceous, glabrous : head as large as the thorax, densely punctulate, 

 with longitudinal and transverse epicranial lines distinct : mandibles blackish at 

 tip : palpi and antennas testaceous, the latter long, sparsely pubescent : thorax 

 very short, much narrower at base than at apex ; base and apex truncate ; hinder 

 angles minute, acute, excurved ; sides slightly rounded, more or less crenate ; 

 minutely and densely punctured, with the disk often dusky ; lateral submarginal 

 line distinct, with a small impression on its inner side towards the base : scutel 

 testaceous, short, wide, obtusely rounded at tip : elytra short, brownish, very finely 

 punctured ; each elytrum with a large testaceous spot near the middle, and four 

 longitudinal impressed lines: feet and beneath yellowish-testaceous. Though this 

 is an abundant species, yet I have not seen it described. It is, perhaps, the Jlde- 

 Una complanata of Dej. Catal. 



Cucujus oblongus, Fabr., varies much in size — from 2| to 6 lines in length. 



Cucujus biguttatus, Say, varies much in size, color and form of the antennal 

 joints. 



Tetratoma, Herbst. 



1. T. obsolela. Blaek, beneath piceous ; elytra obsoletely maculate with ru-
