[July 
The female speciniens from which Mr. G-reene made his description 
of this species, have the hairs on the dorsal surface of the abdomen 
rubbed olF, although, generally, the hairs on that part of the abdomen 
are much scattered and sparse. 
The only differences that I can see between the females of this spe¬ 
cies, and camjjestriH, are that the former species has the hairs of the 
head yellowish, while those on the head of the latter species are entirely 
black 5 the black band in the middle of the thorax of campestris is 
broader and more distinct. 
The males above described, and which I think belong to this species, 
present no characters by which they could easily be separated from 
those of campestris^ and they vary just as much in the coloration. 
The specimen, before me, of B. SucMeyi Greene, which seems to be 
the typical specimen (as it has the word “Type” attached to the pin), 
is a S , and not a 9 5 as indicated in Mr. G’s description, and the apical 
segment is apparently altogether black, and not yellowish. However, 
in considering the many variations which occur in the males of A. 
campestris^ I am inclined to believe that this is the male of A. insularis, 
as well as the other two varieties described above. 
Var. c, of the male, answers in many particulars to the description 
given of the male of B. Sitkensis, but as it seems more related as a 
variety of A. insularis^ it would probably be best to allow it to remain 
here, until more specimens have been accumulated. It is certainly an 
ApatJms.
