104 [October, 1844. 



Black, immaculate, very shining : head sparsely and very finely punctured; 

 eyes approximate : antennae, palpi and mouth piceous, the first with the clava 

 fuscous : thorax very finely punctured, with the ordinary basal punctures well 

 defined : elytra with distant shallow punctures ; besides the ordinary basal and 

 subsutural series of punctures, there are about three much abbreviated discoidal 

 ones, each consisting of two, three, or four punctures : feet and tip of abdomen, 

 black-piceous ; tarsi paler. 



Scaphisoma, Leach. 



S. terminatum. Black; posterior edge of the elytra, tip of abdomen, feet 

 and mouth, rufo-piceous. — | 1. long. Pennsylvania. 



Scapkidium terminatum, Melsh. Catal. 



Black, shining, glabrous, very minutely rugose : elytra with the apical mar- 

 gin rufo-piceous; sutural stria distinct; terminal segments of abdomen, feet and 

 mouth, rufo-piceous. Differs from convexum, Say, in being much smaller, and 

 apparently impunctured. It is more closely allied to agaricinum, Linn., than 

 to the former species. 



SUphidx, Leach. 



Pettis, Kugellan, Fabr. 



1. P. quadrilineata. Black; each elytrum with four longitudinal raised 

 lines. — 4f 1. long, 2 1. wide. Pennsylvania. 



Opatrum striatum, Melsh. Catal. 



Body oblong, black-piceous : head weakly and obtusely indented on the front, 

 slightly transversely convex between the eyes; punctured, punctures numerous 

 and profound : antenntE, palpi and mouth, piceous : thorax short, transverse, 

 a little wider behind than before; basal edge almost rectilinear; anterior margin 

 sinuate; sides- obtusely rounded ; surface punctured like the head, with a trans- 

 verse impression before the middle of the base, and another obsolete one on the 

 middle of the disk; dorsal line fine, distinct on the middle : scutel transverse- 

 oval, sparsely punctured : elytra more than three times the length of the thorax, 

 with the sides slightly rounded ; four entire longitudinal raised lines, sutural 

 and lateral edges also elevated, the spaces each with four series of deep punc- 

 tures. 



2. P. marginata. Black ; margins of the thorax and elytra piceous, the last 

 with four raised lines. — 3 1. long, 1§ 1. wide. Pennsylvania. 



Oblong, black-piceous : head as in the preceding : antennce, mouth and palpi 

 piceous : thorax altogether as in the preceding, only the dorsal line is distinct 

 and entire, and the lateral margins dull rufo-piceous : scutel as in the preced- 

 ing : elytra comparatively shorter than those of the preceding, and sculptured 

 like them, only the spaces contain but two or three series of punctures; lateral 

 margins dull rufo-piceous : beneath and feet reddish-brown, the latter slightly 

 piceous. The tibiae in this and the preceding species, are furnished with two 

 spurs at tip, and the anterior pair is very finely denticulated. 



Nitidulidx, MacL. 

 Cercus, Latr. 

 1. C. punctulaius. Piceous; head and terminal segment of the abdomen, 

 rufo-piceous ; feet testaceous. 1 1. long. Pennsylvania.
