1>1. L'G, Figs. 7, !). 



Head smooth or very finely and transversely corrugate, the front pro- 

 jecting forward between the antenna 3 , but subtruncate or broadly rounded ; ' 

 antenna; with the basal and apical joints darker than the rest. Thorax rather 

 faintly and somewhat distinctly punctate, as well as transversely corrugated, 

 especially in the middle. Hemelytra rather coarsely punctate in longitud- 

 inal lines, following the course of the veins, more or less infuseated ; the 

 membrane slightly infumated. Abdomen broad and very well rounded. 



Length of body, 5.25"""; antenna?, 2.5 ram ; breadth of thorax. 1.65 mm ; 

 abdomen, 2.25""". 



The name is given in honor of Mr. G. B. Chittenden, topographer of 

 the Hayden Survey, engaged during its exploration of Colorado.

5. CHOLULA Distant. 



A single species, represented by a single, imperfect, headless specimen 

 from Green River, Wyoming, is referred here from its near resemblance to 

 one of the species described by Distant. It differs, however, in several 

 points: the basal margin of the thorax is hardly concave at the base of 

 the scutellum, but straight, while elsewhere it is convex ; there is but the 

 faintest sign of any catenation of the scutellum, and I can not see that 

 either corium or clavus is punctured. 



CHOLULA TMOUTTATA. 

 PI. 7, Fiji. L'l. 



Body slender with parallel sides, fully three times longer than broad. 

 [Head wanting ] Thorax rounded subijuadrate, broader than long, the ante- 

 rior a little shorter than the posterior lobe, and distinctly separated from it
