OF PHILADELPHIA. 253 



The nervures of the liemelytra are yellowish to the penultimate 

 anastomosis, beyond which they are brown; the two particular 

 anastomoses are strongly marked with blackish : head testaceous : 

 thorax but little varied with black : scutel black, with the usual 

 testaceous lines : tergum black, densely covered with the golden 

 hair : beneath pruinose. 



Length one inch and a half nearly, to the tip of the hem- 

 elytra. 



This species differs from the preceding in being [333] smaller, 

 and in having the golden pubescence, which is more dense on the 

 head and thorax. 



Found near the Konza village. 



5. C. PARVULA. — Anterior thighs with three parallel, subequi- 

 distant spines. 



Inhabits Missouri. 



Body dull testaceous : head with a dilated dusky line each 

 side on the front : stemmata reddish-yellow : antennae rather 

 large, longer than the head : labrum with dusky rugae and a 

 longitudinal impressed line, abbreviated at the termination of 

 the rugae : thorax indistinctly varied with black, the lateral edge 

 not prominent : scutel quadrilineate, lines dilated, abbreviated, 

 iutermediate ones very short, terminal x hardly elevated : hem- 

 elytra, with a reddish-yellow reflection : nervures blackish be- 

 yond the middle ; costal nervure very conspicuously so ; no mar- 

 ginated anastomosis; segments of the tergum dusky at base: 

 thighs and trochanters varied with black : anterior thighs tri- 

 dentate ; teeth prominent, subequidistant, parallel, posterior one 

 longest, anterior one shortest. 



Length to the tip of the hemelytra seven-tenths of an inch. 



A very small species. I have a specimen from near the Rocky 

 Mountains, which is entirely green, it is a female, and probably 

 of the same species with the above. Its length to the tip of the 

 hemelytra, is four-fifths of an inch. [334] 



6. C. SYNODICA. — Black, varied with pale testaceous; tergum 

 annulate. 



Inhabits the base of the Rocky Mountains. 



Body above, black, varied with pale testaceous : head with a 

 transverse line before the eyes, and about three triangular spots
