8 ENTOMOLOGICAL NEWS. [January, 



I believe the centre of its distribution to be the Cceur d'Alene 

 district of Idaho, where I took it on my visit in 1889. C. tuber- 

 culatus, reported from Vancouver Island, occurs also in the main- 

 land at Portland, Oreg., and Tacoma, Wash., but is still rare. 



A perusal of these lines will show that in this genus every one 

 of the divisions, except Pemphus, which contains but a single 

 species, has been found to have a distribution much wider than 

 that known to science when last written up, and I await further 

 developments with a great deal of interest. Cannot some of the 

 readers of Ent. News furnish us with more notes on geographical 

 distribution ? Too little attention seems to have been paid this 

 part of our science, and it is something in which every one can 

 help.
