and posteriorly angulated, bearing stiff bristle-like hairs. Proboscis as long 

 as tbe head (fig. 6), tawny proximally but shiny-black distally, the palpi as 

 long as and applied to the proboscis, tawny with a darker tomentum, and 

 shaped as in H. benhami. Occiput with a yellow tomentum and a row of 

 post-orbital bristles, while on the lower portion are scattered bristles and 

 golden hairs. Antennae nearly as long as the height of the head, the 1st 

 and 2nd joints tawny with a yellow tomentum. not long and of about equal 

 length, each having a pre-marginal whorl of short black bristles ; 3rd joint 

 black but tawny at the base, shaped as in H. benhami, about two and a 

 half times as long as the first two joints together and with a scattered 

 yellow pubescence, the j)ubescent flagelluni is 2-jointed and about a quarter 

 ibhe length of the 3rd antennal joint ; the 1st joint is short, and the 2nd 

 ends in a terminal appendage nearly one-half the length of the second. 



Thorax not prominently humped, of a yellow colour, due to a dense 

 tomentum, but tawny on the margins of the humeri and dorsum before the 

 wings where the tomentum is absent. On the dorsum is a pair of rounded 

 longitudinal ridges, not reaching the yellow scutellum, but ending in a

median transverse depression, between which and the scutellar suture is a 

 short tubercle-like ridge. Each ridge carries a row of closely set dorso- 

 central and post-sutural bristles ending in 2 large widely separated con- 

 vergent bristles (fig. 7), the acrostichals being represented by 4 rows of short 

 closely set bristles, which terminate in an irregular clump just posterior to 

 the line of the dorsal suture ; there is a single humeral bristle and short 

 stiff black hairs, a single supra-alar bristle, a pair of post-alars the anterior 

 one on the angle ])eing a stiff hair, a row of strong noto-pleurals, a row of 

 weak pre-suturals(?) with a corresponding row posterior to the dorsal suture, 

 while on the dorsum between the pre-suturals and the noto-pleurals and also 

 between the anterior dorso-centrals and the humeral are scattered a few 

 weaker ones ; on the pro-thorax is a pair of straight and divergent tawny 

 bristles, while the scutellum bears 4 convergent marginal bristles, the apical 

 pair being crossed. The pleurae are bare and halteres tawny. 



Wings hyaline, but distally the marginal cell is faintly clouded with 

 yellow, and near the origin of this cell, in line with the apex of the auxiliary 

 vein, is a brown fusiform spot ; the 1st section of the 3rd vein, the anterior 

 transverse and the lower margin of the 2nd basal cell are also bordered with 

 brown, giving a banded appearance to the wing. Auxiliary, 2nd, and 3rd 

 veins formed as in H. benhami ; anterior transverse vein not oblique, the 

 posterior sinuated, not parallel to the hind margin of the wing, and nearly
