HETEROPTEROUS HEMIPTERA. 367 



Body blackish, with slender, yellowish transverse lines : head 

 greenish-yellow, with a broad dusky line on each side of the mid- 

 dle, not extending to the orbit and hardly reaching the vertex, 

 but dilated over the mouth : thorax with twelve to sixteen linea- 

 tions : hemelytra minutely wrinkled longitudinally ; transverse 

 lineations not larger on the inner margin ; lateral groove pale 

 fulvous, particularly towards the base where it is hooked, and 

 on the middle it has an oblique black spot : tergum at base 

 sanguineous : pectus and postpcctus black ; feet yellowish ; ante- 

 rior pair black at tip : intermediate pair black on the tibiae and 

 the tip of the thighs ; posterior pair, tibiae and tip of the tarsi 

 black : venter at base sanguineous. 



Length two-fifths of an inch. 



This was found in Mexico by Wm. Bennett, and sent me by 

 Mr. Maclure. In point of size it resembles interrupta nob., 

 which, however, is but obsoletely wrinkled at the base of the 

 hemelytra : its transverse lineations are much more undulated, 

 and the abodomen is pale yellowish beneath ; the feet also are im- 

 maculate. 



3. C. MERCENARIA. — With the line subequal and an imma- 

 culate space at base. 



Inhabits Mexico. 



Body smooth, pale yellowish ; head immaculate, convex before, 

 and with an obsolete carina and a few punctures : thorax with 

 about eight or nine transverse black lines : hemelytra with 

 numerous, equally slender, transverse somewhat confused, black 

 lines : a large immaculate space at basej channel of the exterior 

 margin interrupted, immaculate, excepting a dusky dot at tip 

 and a less obvious one beyond the middle ; tip rounded : venter 

 blackish, lateral margin and posterior margins of the segments 

 whitish. 



Length one-fifth of an inch. 



On comparison with the alternata nob., it may be distinguished 

 by the equality of the lineations of the hemelytra, those of that 

 [812] species being much more regular and wider on the inner 

 anterior margin than on other parts of the hemelytra. The 

 thorax and hemelytra also of that species are minutely rugulose.
