broad darker stripe in the centre; it is praetically Irce froni, pu- 

 bescenœ except on the central darker stripe, wherc it is whitish 

 and sparse. Hypopygium fairly large, shining aeneous and brown 

 and possessing rather sparse pale pubescence. 



Legs black with the extrême tip of the anterior femora and thc 

 base of ail the tibias brownish-yellow, or yellow, as wcll as the 

 middle nietatarsus, and the tips of thc othcr joints of the middie 

 tarsi, and ail the tips of the front tarsi ; tl;e three pairs of femora 

 are rather svvollen ; the hind pair is much more swollen and in 

 addition its lower distal half bears tvvo rows of about eight sliarj) 

 black spines, between which the tibia? can fold back ; the hind 

 raetatarsi are swollen, a little less thaii tlic tibia- and iiK.re than 

 the following joint of thc tarsns. and Ihcre is little gradation 

 between thèse threc joints, so that tlu> hind legs appear uimsually 

 thick and clnnisy. The joints of ail the tarsi bare short, bnt 

 distinct, spnrs and those ou the hind pair are rather hidden by the 

 dense pnhescence. The pubescence on tiie npper part and skies of 

 the anterior pair of legs is rather short, pale and inconspieuous, 

 while they are quite bare on the under-surfacc ; on the liin'd legs 

 it is rather longer, denser, erect and whitish in coloiir ; on thc 

 base of the npper part of the tibiœ on the inside thcrc is a fringe 

 of about six or seven white bristles.

 whitish, with a yellowish margin ; the alar pair are small and 

 bear simple whitish fringes ; the thoracal pair are much longer 

 and also possess white fringes which are much longer and compo- 

 sed of compound hairs as in Syriffa. Haltères yellow, with a 

 brown base. 



Female: Very similar to the maie but usually largcr. The 

 frons is not so shining and is entirely black, except for two thin 

 Unes of whitish-grey dust on its side margins, which extend from 

 the sides of the face to the lower margin of the vertex, where 

 they end abruptly ; vertex very broad. The punctation on the 

 frons, vertex, thorax and abdomen is rather coarser in the malc 

 and the pubescence on the thorax and abdomen is denser. The 

 apex of the abdomen is more pointed.
