basal impressions obsolete ; scutellum with a longitudinal impunctured space 

 in the middle : elytra strongly punctate-striate, the interstices rugose, and with 

 distant punctures : pectus punctured and colored as the thorax ; abdomen 



: femora dull chest nut -red ; tarsi color of the palpi ; tibia? darker. 



Distinct from the picipes, Fabr. 



3. C. fuscipes. Fuscous; three basal joints of the antennae and feet 

 testaceous, 4 1. long ; U 1. wide; J*; 5} 1. long; 1| 1. wide. Pennsylvania. 



Cistela fuscipes, Melsh. Catal. 



Brown, clothed with a fine, dense, ashy-pubescence : head very minutely 

 and confluently punctured, with the front somewhat indented ; a longitudinal 

 impressed line, extending from the vertex to the apex of the clypeus, very 

 distinct in the ; frontal suture obsolete ; clypeus at tip, labruni and palpi, 

 dull testaceous : thorax punctured, punctures intensely minute and crowded ; 

 basal impressions obscure ; anterior edge dull rufous ; posterior angles promi- 

 nent and acute, particularly in the V : scutel punctured as the thorax : elytra 

 punctate-striate, with the stria? profound and the punctures transverse and 

 close set, the interstices punctured as the thorax, and in the rather alternately 

 wide : beneath as above ; feet pale yellowish-testaceous, the tibia? and tarsi 

 rather deeper. The specific name is somewhat inappropriate. 



C. brevis. Black ; antenna?, palpi and feet rufous. Say, Journ. Acad. Nat. 

 Sc. hi. 269. It may be added to the above character that the antenna? are 

 serrate, mostly fuscous, with three basal joints testaceous. 



C. sericea. Pale testaceous, immaculate ; elytra absolutely striated near 

 the suture. Length about one-fifth of an inch. Say, Journ. Acad. Nat. Sc. 

 iii. 270. Long's Expedit. App. p. 285. 



Var. ? a. Fuscous, antennae, palpi, tibia?, tarsi and suture of the elytra, 

 rufous ; the stria? of the latter almost entirely effaced. Length somewhat 

 less than the preceding. Cistella pulla, Melsh. MS. 



Var. ? b. Dull rufous, with the head and throat above blackish ; stria? of 

 the elytra feebly defined. Length of var. a. Smaller, but altogether like 

 thoracica, Fabr., variety of murina, Fabr. 



4. C. nigrans. Black-brown ; elytra punctate striate. 33 1. long ; 1 L wide. 

 Pennsylvania. 



Cistela atra, Say, Journ. Acad. Nat. Sc. v. 242. 



Black-brown, ashy-pubescent ; head deeply and not closely punctured ; 

 frontal suture distinct ; eyes closely approximating above ; antenna? fuscous ; 

 palpi piceous ; thorax subquadrate, slightly widest in the middle, with the 

 sides obtusely rounded ; truncate in front, slightly waved behind ; punctured, 

 punctures profound, numerous, but not crowded ; an obtuse impression in 

 front of the scutellum : elytra deeply punctate-striate, the interstices convex, 

 rugose ; beneath and feet piceous. The specific name atra has been applied 

 by Fabricius to a different species. 



Var. a. As in the preceding, with the antenna?, palpi and feet testaceous ; 

 sometimes the antenna?, tibia? and tarsi, dull rufous. 4 1. long. Alabama.
