Plate 28. 



The width and shape of the black blotches on the second abdo- 

 minal segment, as well as the sharpl)- defined 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. ciccutiens. 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 tawnj', and the 

 pale triangles are much less distinct.

 Colonel Yerbury remarks, is " common and generall)- distributed," is

 of May until at any rate the third week in August. The localities and 

 dates of the specimens, which, unless otherwise stated, were taken
