Hemiptera of Mt. Washington. 



Mt. Washington is our highest elevation and supports a rich 

 and diversified fauna upon its slopes; it has therefore received a 

 great deal of attention from entomological collectors and students 

 of distribution. In the present list, 96 species are recorded from 

 the mountain, the altitude of capture being mentioned in most 

 cases, but it should be remembered in connection with those taken 

 on the boreal summit that most of the species normally confined 

 to lower levels may on occasion be carried by ascending atmospheric 

 currents to altitudes where they are quite unable to maintain a 

 continuous existence. Some of the rarest and most remarkable 

 of the New England Hemiptera have been found on Mt. Washing- 

 ton: — Sciocoris micro phthalmus, a Palaearctic species of which 

 not more than three or four examples have been taken in North 

 America; Hespero phylum heidemanni, the only Nearctic repre- 

 sentative of the peculiar family Termatophylidae; Zicrona caerulea, 

 a cosmopolitan species of very rare occurrence in this part of the 

 world; and Galeatus peckhami, reported from Japan and from a 

 few widely separated points in North America. 



Numerical Summary. 



Nearly 1500 species of Hemiptera-Heteroptera are now known to 

 inhabit America north of Mexico, of which 419 are here listed as 

 occurring in New England. Of the 37 North American families 

 all but 5, the Pyrrhocoridae, Isometopidae, Dipsocoridae, Schizop- 

 teridae, and Gelastocoridae, occur within our limits, and it is very
