OP PHILADELPHIA. 209 



Length, less than three-twentieths of an inch. 

 [Also a Pacliyhracliys. — Leg.] 



3. C. FASCIATUS. — Yellowish, varied with rufous : elytra with 

 three bands ; beneath rufous. 



Inhabits Missouri. 



Body yellowish, punctured : head rufous ', orbits yellowish ; 

 punctures crowded, irregular : eyes black, transverse : antennse 

 dusky at tip : labrum dusky at base : thorax varied with yellow- 

 ish and rufous ; punctures sometimes confluent ; posterior angles 

 a little produced backwards and acute: [438] scutel rounded at 

 tip : elytra striate, with large, deeply impressed punctures ; punc- 

 tures at tip irregularly disposed ; three dilated, somewhat undu- 

 lated, rufous fasciae : beneath rufous : feet somewhat paler. 



Length about three-twentieths of an inch. 



Found near the Konza river. At first sight it might be taken 

 for a variety of C. congestus, of which the spots had become 

 confluent into bands, but the much punctured thorax is a dis- 

 tinguishing character that cannot in this instance be mistaken. 



4. C. PUNCTiPES. — Black; front two-spotted; thorax with 

 three spots, and margin rufous; elytra varied with whitish 

 spots. 



Inhabits Arkansa. 



Body black, punctured : labrum each side, base of the antennae, 

 three or four small obsolete spots between the antennae, and two 

 larger ones between the eyes, dull rufous : thorax, anterior and 

 lateral margins, two oblique, dilated, abbreviated lines at base, 

 and one at tip dull rufous : elytra with punctured striae ; basal 

 edge, three large marginal spots, of which one is terminal ; a 

 smaller one on the middle, near the suture, and two or three 

 smaller ones near the base, yellowish : thighs with a white ob- 

 long spot near the anterior tip : tail with two dull rufous dots, 

 and a smaller one each side on the terminal ventral segment. 



Length less than one-fifth of an inch. 



Corresponds in some respects with Olivier's [439] descrip- 

 tion of his C. hrunnipes, but besides some other difierences, the 

 antennae are shorter than the body. It may possibly, however, 

 be the same.
