From collare also it may be distiiigiiisliod I)y its small size, the 
much greater jyroportionate size aiul ])i-omineiice of the eyes^ and 
the more equal and less tumid head. (See fig.) 
Spharagemon collare Scudder. 
I have never taken this species in New England, and I regaid 
its presence here as very improbable, but since it has been reported 
to occur on Cape Cod and in New Jersey (Bull. no. 4, ent. div. 
U. S. dept. ngric. ; Bull. 90, N. J. agric. coll. exp. station, p. 34), 
I mention it. 
Prof. J. B. Smith writes me that the specimens referred to 
above were collected by him while in the employ of the U. S. 
dept. of agriculture and forwarded to Washington where the 
determinations were made. Dr. C. V. Riley, who kindly looked 
into the matter for me, reports that careful search through the 
National museum collections fails to bring them to light. 
Consequently I have been unable to examine and identify them. 
Owing to the difficulties in distinguishing the species of this 
genus I regai'd the correct identification of these specimens 
extremely doubtful. I have indicated my reasons, under S. 
ocuJatum, for thinking that possibly that species may be the one 
referred to.
