 fuscous posteriorly ; front and middle coxae often narrowly fuscous at 

 bases, occasionally blackish with yellowish apices; hind coxa usually 

 black, rarely black with reddish apex; front and middle femora and

 times suffused with fuscous; hind tibia brownish to fuscous sub- 

 basally and at apex, with intermediate region somewhat paler but 

 not distinctly annulate; tarsi varying from pale to dark brownish 

 with lighter bases.

 palpi usually more or less fuscous ; tegula usually fuscous posteriorly ; 

 front and middle tibiae without fuscous annuli; hind tibia pale brown-

Mr. J. F. Perkins (British Museum) kindly supplied specimens of 

 this species, from England, and has subsequently confirmed my 

 identification. Other Palearctic material examined by me includes 

 specimens from England, in the Townes collection, and a male taken 

 in Lappland (67°58' N. and 3°34' E.), Sweden, July 25, 1951, by J. R. 

 Vockeroth, and now in the Canadian National Collection.
