 more than any other species in the Nat. Hist. Mus. Collection ; 

 but the latter species is more brightly coloured, and the costal 

 nervure is fulvous instead of brown.

Much resembles the last species, but the face, except the 

 ferruginous proboscis, is entirely black, and the head, face, thorax, 

 and bands on the abdomen above are clothed with dense silvery- 

 white pubescence. The bands towards the tip of the abdomen are 

 slightly bordered behind with fulvous in very fresh specimens, and 

 the terminal segment is clothed above with rich fulvous ; beneath, 

 the abdomen is banded with silvery white, as above, in the male, 

 and clothed with long, recumbent, fulvous hair in the female. Tlie 

 legs are clothed with yellowish- grey hair, the hair on the tarsi 

 being bright fulvous beneath, and more or less above, at least on 

 the middle tarsi.

 island, December, 1897, and January, 1898. Very common on
