Chelynia ricardonis, n. sp. (? rubi, subsp.).

 head above, and sides and anterior part of mesothorax, with con- 

 spicuous white hair ; tubercles densely fringed with dull white 

 hair ; abdominal markings bright lemon yellow (cream-coloured 

 in rubi), the band on first segment broad and entirely curved 

 at sides ; that on second interrupted sublaterally, the lateral 

 pieces of it pyriform ; third segment with a rather short 

 median stripe and small lateral spots ; fourth with a median 

 butterfly-shaped yellow mark ; hind basitarsi long, subclavate, 

 with reddish hair on inner side. 



Hab. — Vernon, British Columbia, June 19, 1902 (MissRicardo).. 

 British Museum. This has the structure of C. rubi {betheli Ashm.), 

 but differs in the colour of the markings and pubescence. It is 

 probably a valid species, but it may prove to represent onlv a local 

 race or subspecies of C. rubi. The latter occurs at Seattle and 

 Olympia, in the State of Washington. Although the two species 

 are not very far apart geographically, Vernon is an inland locality,, 

 with doubtless a very difi'erent fauna from that of the coast. 



Anthidium porterœ Ckll. 

 Calgary, one male (Miss Ricardo). British Museum. Also 

 from Calgary, from some collector, is a male A. tenuiflorce Ckll., a 

 form with the scape of the antennae entirely black.
