INSECTS OF BERLAH, NEW MEXICO. Ill 



a pale spot at each incisure, and the corium is dark sanguineous 

 with the hind edge and costa narrowly pale. 

 Coriwcus ferus Linn. 



One strongly marked specimen. This widely distributed species 

 seems to follow cultivation and irrigation throughout the arid re- 

 gion of the West. 



Coriscus sp. 



There is one example of another species I have not been able to 

 locate. This is a difficult genus and sadly needs revision. 



Hygrotrechus remigis Say. 



Two examples. 

 Notonecta sp. 



One immature example. 



HOMOPTERA. 

 C'ereNH turbida Godg. 



Eight male and five female examples. 

 Thelia univittata Harris. 



One male and three females. 

 Microceiitrus perdita Am. & Serv. 



Four examples. I found this species not uncommon in Colorado 

 on the lower branches of the scrub oaks where they lay close to the 

 ground. 



Aphrophora irrorata Ball. 



An interesting species of which there are two specimens in the 

 lot. 



Clastwptera obtusa Osborn. 



Five male and four female examples. While collecting in Colo- 

 rado I took this species only on pine on the mountain sides. 



Clastoptera xanthocephala Germ. 



Two examples. These are of the black form which I have taken 

 to be the characteristic type of the species. The color above, espec- 

 ially on the pronotum, is of an intense shining black ; a transverse 

 line on the base of the vertex, another near the fore margin of the 

 pronotum, and two converging lines on the scutellum, are clear
