These two forms, although differing so much in coloration, are 

 evidently the opposite se.KCS of the same sjieeies. I collected speci-

 having the same form of second iintcnnal jtjint as l)oth of these 

 forms possess. 



In the same volume of the periodical above referred to, on jiages 

 221 and 222, I gave a table of the known s])ecies of Toxophora 

 occurnp.g in North .\merica, and described two new species; I give

 of species, as follows : 



1. Wings with three submarginal cells 2 



Wings with only two submarginal cells; crossvein at apex of 



diseal cell not angular, destitute of a stump of a vein
