the latter with very short, weak, white spines. Valves of male with long

 with the veins and costal margin greenish. Sternum black. Abdomen 

 above, and beneath at base, except margins of segments, black. Length,

Pullman, Washington (C. V. Piper). This form may prove to be a 

 variety of mcdius on the examination of large series, but it differs in 

 having a black sternum and milky elytra.

Corfield, Vancouver Island, B. C. (Mr. Clermont Livingston). 

 This is one of many most interesting things which Mr. Livingston's 

 industry has turned up in Vancouver Island, and I take pleasure in 

 dedicating it to him. It is near occideiitalis, but is longer, more robust, 

 and differs in coloration.
