nervures ferruginous ; third s.ni. narrowed more than half 

 to marginal. Legs dark, the small joints of the tarsi reddish ; 

 basal joint of middle tarsus broad and flat, MJth light golden 

 hair beneath ; hind legs with a copious, beautifully plumose 

 scopa, Mhich is filled with bright orange pollen, presumably 

 of one of the Compositie ; abdomen rather broad. 



Allied to A. Krigiana, Rob., and A. lauracea, Rob., but con- 

 siderably larger. In Yiereck's table of north-western species 

 it runs nearest to A. nud'unediocornis, Vier., but it is not that. 

 In Bruner's table it runs nearest to macilenta, Prov., and 

 trizonata (Ashm.), but it is neither of these.
