Plate 28. 
The width and shape of the black blotches on the second abdo- 
minal segment, as well as the sharply denned pale triangles and hind 
margins on the following segments afford a ready means for the dis- 
tinction of the female of this species from that of C. accutiens. In 
the specimen illustrated in the plate the blotches on the second seg- 
ment are somewhat obscured by the wings, which are in the resting 
position. The markings of the male abdomen are similar to those of 
the female, but the sides of the basal portion are more tawny, and the 
pale triangles are much less distinct. 
The Museum series of British specimens of this species, which as 
Colonel Yerbury remarks, is " common and generally distributed," is 
a fairly long one, and shows that it is on the wing from the latter end 
of May until at any rate the third week in August. The localities and 
dates of the specimens, which, unless otherwise stated, were taken 
and presented by Lieut-Colonel Yerbury, are as follows : — Nairn, N.B.,
