" Through the kindness of many friends I have had an opportunity 

 to examine specimens from the Provinces of Quebec, Ontario, and Colum- 

 bia, in British America; from nearly all of the New England States, besides 

 Illinois, Iowa, Michigan, and Colorado. The genital segment of the male 

 is deeply excavated, and with two short processes on the middle. The 

 tergum is often bright red, which colour becomes brownish in more 

 mature specimens. The humeral angle is usually more or less black. In 

 some specimens there is a series of minute black dots each side of the 

 venter, and a few obscure spots distributed over the ventral surface."
