separation begins near the top of frons and is hardly undulating but 

 runs nearly straight across the eye to the narrow zone, leaving the 

 widest part of the small facets at about the middle of the head (when 

 viewed sideways) ; the narrow zone extends right up to the vertical 

 space at where it bends anteriorly a short distance from the vertex 

 along the frontal margin, and is very slightly narrowed above, and its 

 vertical dividing line is not so conspicuous as the horizontal one ; eyes 

 in death deep greenish black with a shimmer on the part of small 

 facets, but the large facets yellowish brown, and there is no bands. 



Thorax rather browner than in the female and with rather 

 longer much abundant erect blackish pubescence, and with much less 

 yellowish depressed pubescence, the tufts on the upper bases of the wings 

 and on the posterior margins of the postalar calli are less conspicuous 

 t and yellowish red, the long pubescence on the spaces between the 

 humeri and praealar calli are much longer and very yellowish. Scutel- 

 lum usually shorter and evenly rounded posteriorily, with much longer 

 much abundant erect blackish pubescence, and with a less abundant 

 pale marginal fringe. Pleurae covered with much abundant more longer 

 and much yellowish pubescence, and with reddish yellow tufts on the 

 postero-upper margins of the meso- and meta-pleurae, the tufts on the 

 prothorax and on the upper margin of the pteropleurae are less 

 conspicuous, the former being yellowish and the latter reddish. 



Wings, squamae, and halteres almost as in the female, but the 

 former comparatively shorter, and the next much glassy especially in 

 the alar pair. 



Legs much darker than those in the female ; pubescence on the 

 front coxae yellow ; the front tibiae brown, gradually darkened apically, 

 covered with black pubescence all over the surface, but with very few- 

 reddish yellow hairs intermixed about the basal third, posterior two 

 pairs much darker owing to that the hairs almost all are black with 

 a very few reddish yellow pubescence intermixed on about the basal 

 two-thirds especially on the underside ; femora similarly coloured as
