67. MEGACHILE FLAVIPENNIS. B.M. 



Female. Length 7 lines. Black, head and thorax very 

 closely punctured, the puncturing strongest on the thorax and 

 running into each other, forming on the anterior portion irre- 

 gular transverse rugose striation ; the faee above the clypeus as 

 high as the anterior stemma clothed with a short black pubes- 

 cence ; the clypeus rugose, mandibles very stout, covered with 

 elongate punctures, quadridentate. Thorax, the disk thinly 

 covered with short fulvous pubescence, on the sides of the m eta- 

 thorax it is longer, more dense, and of a paler colour ; wings 

 yellow, their apical margins fuscous, the nervures and outer 

 margin of the tegulae rufo- testaceous ; legs ferruginous. Ab- 

 domen thinly clothed with rufo-fulvous pubescence, that on the 

 basal segment being pale fulvous, particularly at the sides ; the 

 margins of the segments have a fascia of rufo-fulvous pubes- 

 cence, beneath at the base clothed with fulvous and at the apex 

 with ferruginous pubescence.
