Genus Xylocopa. 271 



*48. Xylocopa rufescens. 



Female. — Rufo-foscous ; the head and thorax in some 

 examples inclining to black or dark-brown ; the abdomen 

 varying in depth of colour ; the pubescence rufo-fulvous ; 

 that on the legs and at the apex of the abdomen being- 

 bright rufo-fVdvous ; the antenna3 ferruginous, sometimes 

 more or less fuscous above ; the wings fulvo-hyaline, palest 

 at their posterior margins, the nervures rufo-testaceous, 

 the tegulffi of a deeper tint of the same colour ; some speci- 

 mens have more or less of a narrow pale fulvous fringe on 

 the apical margins of the segments of the abdomen, these 

 are only observable in very fine specimens : the fourth, 

 fifth and sixth segments have a maro-inal frino-e of lono; 

 rufo-fulvous pubescence. The male closely resembles the 

 female, but the legs are more elongate, and the pubescence, 

 in the only example I have seen, is of a paler colour, parti- 

 cularly that which clothes the thoi*ax above. Length of 

 both sexes \2\ — 13 lines.
