HYMENOPTERA. 165 



the segments have a transverse depression and are covered with 

 deep but scattered punctm-es ; the pollen-brush on the abdomen 

 beneath is entirely black. 



Male. Length 6 lines. — Closely resembles the female, the 

 pubescence is longer and the tarsi beneath are covered with 

 fulvous pubescence, the claws ferruginous ; the basal joint of 

 the anterior tarsi simple ; the apical segment of the abdomen 

 vertical, down the centre of which is an elevated carina ; the 

 margin deeply notched in the middle, and on each side two 

 smaller notches. 



Obs. This species resembles M. angularis, but is very distinct ; 

 the wings are entirely purple, and the pollen-brush is entirely 

 black ; it is altogether a larger and more conspicuous insect.

65. Megachile cognata. 



Female. Length 7h lines. — Head, thorax and legs black, and 

 clothed with black pubescence ; abdomen entirely clothed with 

 rufo-fulvous pubescence ; wings dark fuscous, darkest towards 

 their apical margins. Head, the clypeus convex, and having at 

 the sides some long, rigid, dark brown pubescence, its margin 

 rounded ; mandibles very stout, coarsely sculptured longitu- 

 chnally, having a short groove towards their apex, which is armed 

 with two obtuse teeth. Thorax, the calcaria, as well as the fe- 

 mora beneath, ferruginous. 



Obs. This species closely resembles M. mystacea and rufiven- 

 tris, but is quite distinct from both ; the difference in the form 

 of the face distinguishes it from rujiventris, whilst its size, colo- 

 ration of the wings and calcaria will separate it from M. mystacea, 

 in addition to which the pubescence of the abdomen is much 

 longer.

 testaceous towards the base of the wings, towards their apex they
