In the male the abdomen is bi'owii, witli a ceutial dorsal black sti'ipe 

 which ex[)aiid!S on and covers the apical half of the third segment; the 

 fourth segment is black and nearly completely covered dorsally with a 

 3^ellow tomentuni. In the female the abdomen dorsally is black with 

 white tomeiitum on the incisions of the segments ; nearly the whole of 

 the fourth segment is covered with a jellow tomentum ; this tomentum 

 extends to the fourth segment of the otherwise black venter. 



All hairs, bristles, and legs are black. 



Bristles. — The head contains two pairs of vertical bristles ; the outer 

 divergent pair are smaller than the inner convergent pair. One very 

 slender pair of postvertical convergent bi-istles ; two pairs of ocellar, the 

 posterior erect and small, the anterior strong and proclinate. In the 

 male there is only one pair of reclinate-divei-gent fi'ontal bristles ; the 

 female has three additional pairs, of which the middle are proclinate and 

 the others proclinate-divergent. About four pairs of cruciate bristles. 

 Below each vibrissa there is a row of about ten convergent-proclinate 

 bristles near the oral margin. Postorbital bristles very small. 



The dorsal biistles of the thorax are disposed on each side of the 

 median line as follows: — Three humeral; one strong (central) and two 

 weak posthumeral ; two uotopleural ; one presutural ; two supra-alar ; 

 two intra-alar ; two post-alar; six dorso-central ; one apical acrostichal. 

 The other acrostichal bristles are mostly obsolete, but if present are very 

 small. 



The ventral bristles of the thorax are disposed on each side as 

 follows: — Three or four pro-pleural ; a row of seven meso-pleural situated 

 on the border nearest the insertion of the wings ; three sterno-pleuial ; 

 three ptero-pleural, small, situated immediately above and forming part 

 of the tuft of hairs below the insertion of the wings; about six hypo- 

 pleural. 



The scutellum contains three pairs of long bristles — one lateral near 

 the base, reclinate ; one lateral in the centre, divergent ; and one apical, 

 cruciate. Sometimes there is also a small pair placed widely apart on 

 the dorsum. 



The abdomen contains a pair of lateral bristles on the apical margin 

 of the first segment, one lateral and one median pair on the apical margin 

 of the second segment, about six doi'sal pairs of marginal bristles on the 

 third and fourth segments, and about as many ventral.
