i])P. nvranG;ement o£ the liair on thorax it is like Af. seiningilifs 

 (CI<11.), but that is a considerably smaller species, and the 

 male is quite different. Tt is also close to M. nigrost'gnatn, 

 Ci<ll., but the facial qnadrano-Ie. is broader and shorter, the 

 hairless area on apical ))art of second abdominal sef^ment is 

 much less, and the abdomen beneath lacks the conspicuous 

 black hail", contrasting with the pale at sides. Tiie male 

 rohustior, in the same tables, runs to M. gilensis, but differs 

 by the broad lemon-yellow clypeus, the yellow nearly reaching 

 the eye ; also by the yellow spot on labrum and less elevated 

 vertex. It is easily known from M. grindelire by the light 

 hair on tegulfe, very small amount of dark hair on meso- 

 tliorax, &c. It is also close to M. hpMant}ioj)hUa, Ckll., but 

 differs by the ochraceous pubescence, dusky wings, darker 

 antennae, with the third joint twice as long, &c. 



Bomhus edwardsii, var. kenoyeri, var. n. 



? . — Like var, hifarhm (Cresson), but the red colour of 

 abdomen replaced by pale tawny, so that all the light abdo- 

 minal hair is of the same colour. The second abdominal 

 segment has a broad triangle of black hair at base.
