 middle, with its posterior margin flexuons ; and the apex is 

 also dark blue, the upper margin of the blue colour tlexuous ; 

 the apex is broadly truncated, the tvuncature flexuous, the 

 outer angle with a small tooth. The underside is green, 

 with the flanks of the prothorax, a spot or two on the sterna 

 and epipleura, a band on the posterior cox£e, and a transverse 

 band in the middle of each abdominal segment yellow. Pro- 

 sternal process smooth.

Stigmodera viridicincta^ Waterhouse, Tr. Ent. Soc. 1874, p, 543. 



Three examples of this species were received with the above 

 described. They agree in general coloration with the 

 " variety " which I described, having the sides of the thorax 

 deep red ; the elytra yellow, with the sides and apex red ; 

 but in addition to the green at the suture and extreme apex 

 of the elytra there is a transverse spot across the suture rather 

 behind the middle, one of the specimens having another 

 green spot on the disk of the elytron, which is really only a 

 disconnected part of the transverse spot or band across the 

 suture. This last specimen has also the red at the sides of 

 the thorax united by a red band near the base ; so that the 

 whole thorax is red, except a large spot in front and the ex- 

 treme base, w^hich are green.

 entirely deep yellow, except the apex, which is blue.

 p. 132, which seems to call for some reply on my part. 



In a paper on the genus Colias by me in Trans. Ent. Soc. 

 for October 1880, p. 133, I criticised his determination of
