CHAPTER XII. 



The specimens of Hemiptera from this expedition, sent to me for exam- 

 ination, are few in number, but they embrace some very interesting species. 



A Calocoris, which I have provisionally separated from C. rapidus, Say, 

 may be the extreme limit of bright color attained by that species. I sus- 

 pect this to be the case, because specimens of that species, from the less 

 considerable elevations in Colorado Territory, retain the black spots of the 

 pronotum, and some of the fuscous-gray of the hemelytra which obtains in 

 the specimens from the Atlantic region. 



The Corisas exhibit the minute vermiculate and less distinct marking 

 common to most of the species from Mexico. Chlorochroa Sayi, Stal, the 

 most beautiful green Pentatomid of the West, seems to find its most conge- 

 nial home in Owen's Valley, and must be quite abundant there, if we may 

 judge from the large proportion of them brought home by the expedition.
