SAND-FLIES FROM PERADENTIYA. 61 . 
the distance between the posterior fork and the point at which the 
vein joins the third vein. The fork of the fourth vein is almost on a 
level with the posterior fork of the second. The course of the sixth 
vein, which bends down almost at an angle at the tip, is sinuous. 
Male Genitalia.—The distal joint of the superior appendage is 
slightly shorter, and much more slender than the proximal joint ; 
its outlines are somewhat sinuous, and it bears five long, stout, 
curved, sharp chetz, which are arranged as follows :—A pair at the 
tip of the appendage, a pair on the outer margin at about half the 
length of the joint, and a single cheta on the inner margin nearer 
the base. The chetz are equal or subequal. The intermediate 
appendage (morphologically the lower branch of the superior one) 
is slender, pointed, and turned upwards at the tip. It bears. a 
minute, pointed, naked lobe on its ventral surface, and a similar one 
on its external lateral surface. The inferior appendage is much 
longer than the proximal joint of the upper one ; it is slender as 
viewed from the side, and of almost uniform width; the tip is 
narrowly obliquely truncate, and bears a brush of very long and 
slender hairs ; the rest of the appendage is sparsely covered with 
rather shorter hairs, but there are no spines.

Fic. 6.—Male genitalia of Ph. zeylanicus from the right side, x 175. 
The genitalia of this species closely resembles those of P. argentipes, 
from which it is distinguished among other characters by the 
venation of the wing. The venation closely resembles that of 
P. malabaricus (from Travancore) and P. himalayensis, but the 
insect is paler than the former and darker than the latter species. 
Its genitalia are also very different from those of either. 
Several specimens of both sexes were taken at Peradeniya in May, 
June, July, and August.
