56 [May, 1846. 



obtuse impression ; antennae longer than the thorax, filiform, rufous ; first joint 

 clavate, second one-third smaller than the third, which is slightly longer than 

 the fourth ; joints 5 10, subequal, terminal joint longest, rather fusiform; 

 palpi brown, pilose, with the terminal joint robust, obliquely truncate at tip or 

 slightly securiform ; eyes black, transverse, slightly emarginate ; thorax sub- 

 trapezoidal, as wide at base as the elytra, with the anterior edge truncate, and 

 the posterior one slightly bisinuate ; sides very feebly rounded ; hind angles 

 rather acute ; each side of the middle at base with a small and profound impres- 

 sion ; scutellum small, transverse-oval : elytra more than four times longer 

 than the thorax ; an obtuse sutural groove behind the middle ; beneath darker ; 

 feet dull rufous ; tibia? armed with two moderate spurs at tip ; tarsi long, very 

 slender, simple, with the posterior pair 4-jointed, first joint longer than the 

 following ones taken together. 



Var. a. As the preceding, but much lighter tinted. Serropalpus fuscus, 

 Melsh. Catal. This species, in consequence of having the palpi not serrated, 

 cannot be placed in the genus Serropalpus, nor in that of Melandrya ; perhaps 

 it ought to be referred to the genus Scotodes, Esch., of which I have as yet 

 seen no definition. 



Hypulus, Payk. 



H. trifasciatus. Rufous ; head and three elytral bands black. 2J 1. long. 

 Pennsylvania. 



Pubescent, densely and finely shagreened : head black, densely granulate, 

 sometimes with the cranial and frontal sutures very distinct; apex of the clypeus, 

 and mouth rufous ; antenna? rufous, robust, very slightly longer than the thorax ; 

 palpi prominent, rufous, with the terminal joint compressed: thorax rather quad- 

 rate, slightly widest before the middle, with the anterior edge truncate, and 

 bisinuate at the posterior one ; a profound fovea each side of the middle at base ; 

 rufous, sometimes with the middle of the anterior margin dusky ; elytra rufous, 

 with three common, black fascia? ; the first is on the base, broadest on the scu- 

 tellar region, where it sends off a branch towards the middle fascia, which it 

 nearly reaches ; middle or second fascia, is placed beyond the middle, the third 

 or posterior one is immediately before the apex which it almost covers : feet and 

 beneath more decidedly rufous than the elytra. 



Scraptia, Latr. 



S. palUpes. Dark fuscous, feet testaceous : 1 1. long. Pennsylvania. 



Dark brown above, minutely punctured, and shagreened : head black, mi- 

 nutely and deeply punctured, with two longitudinal impressions ; mouth dusky ; 

 palpi testaceous ; antenna? long, filiform, fuscous; thorax short, transverse, trun- 

 cate in front and behind, with the sides rounded ; a large and obtuse impres- 

 sion eaoli side at base ; medial line obsolete : elytra widest behind the middle ; 

 beneath pale brown : feet pale testaceous. 



Var. a. Chestnut brown ; head and thorax darker ; frontal impressions ob- 

 solete ; lateral thoracic impressions small, an obvious one in front of the scutel- 

 lum. Hallomenus minutus, Melsh. Catal. 



Var. b. Size and form of the type ; head black, with the frontal impressions 

 as in Var. a : antenna? as in the type ; thorax impressed as in Var. a, dull tes-
