Hypophlaus nigellus, Welsh. MS. 



Form entirely of the preceding, blackish, strongly tinged with reddish-brown : 

 head not longitudinally indented in the middle, formed and punctured as in 

 the preceding : eyes, palpi and antenna? as in the preceding : outlines of the 

 thorax as in the preceding, with the punctures much more dense : scutellum 

 and elytra formed and sculptured as in the preceding ; beneath and feet 

 entirely as in the preceding. 



6. H. ? teres. Castaneous. 2 1. long ; J 1. wide. Pennsylvania. 

 Hypophlaus teres, Melsh. MS. 



Form of the two preceding species, chestnut-red : head formed as in the 

 preceding, and similarly punctured, with an obsolete impi-essed line between 

 the eyes, which are as in the preceding ; mandibles formed as in the preceding, 

 piceous ; antennae and palpi rufous ; outlines of the thorax as in the preceding, 

 the punctuation as in that of niger : elytra cylindric, slightly narrowed from 

 the base towards the apex, not as wide at base as the apex of the thorax ; 

 sculptured as in the two preceding : beneath and feet dark rufo-piceous ; form 

 of the tibia? and tarsi as in the preceding species. The three last described 

 species cannot with any propriety remain in this genus ; they are more fitly 

 placed in the genus Trogosita. 



Ulojia, Megerle. 



1. U. impressa. Castaneous ; head and thorax profoundly impressed. 5 1. 

 long ; 2 1. wide. Pennsylvania. 



Tenebrio impressus, Melsh. Catal. 



Subparallel, chestnut-brown, glossy: head much and strongly punctured, 

 flattened, with a profound lunate impression before, behind which is a narrow 

 transverse indented line, joined to the former by a short medial indentation ; 

 antenna? dark rufo-piceous, clothed with yellowish pile; palpi testaceous: 

 thorax transverse, plano-convex, widest in the middle, where it is wid<>r than 

 the base of the elytra, strongly emarginate in front, slightly waved behind, 

 with the sides obtusely rounded, and finely margined ; angles subobtuse ; 

 surface minutely and densely punctured, strongly and irregularly impressed on 

 the middle of the anterior margin ; a small obtuse indentation in front of scutel, 

 and frequently an obsolete one on each hind angle ; scutel rounded at apex ; 

 elytra moderately convex, with sides almost parallel and straight, very slightly 

 widest in front of the apical curve ; crenate-striate, the interstices impunctured ; 

 feet and beneath somewhat darker than above, with the femora lighter and 

 clearer. Distinct from the culinaris, Fabr., but resembles retusa, Fabr., in 

 size, convexity, and impression of the middle of the anterior thoracic margin ; 

 from which, however, it differs in other essential characters. 



2. TJ. picea. Blackish-piceous above ; feet castaneous ; elytra narrowed at 

 tip. 3\ 1. long; 1 1. wide. Pennsylvania. 



Tenebrio piceus, Melsh. Catal. 



Ovate, blackish, tinged with reddish-brown, picous : head finely mgose- 

 pnnctured ; slightly convex and hardly transversely indented, between the eyes 

 and antenn:e, anteriorly obtusely rounded ; month and palpi testaceous-yellow ; 

 antenna* rathermore slenderthanis common, pale In-own, with two nasal joints 

 and tip of the terminal one paler: thorax transversly subquadrate, slightly
