THe genus Harpagomyia was founded by de Meijere in 
1909 for a Culicid fly found in Java by Jacobson, with 
very remarkable habits, and with a most pronounced 
adaptation of its mouth-parts, the mandibles and maxillae 
in both sexes being absent. In the previous year the same 
fly had been described by Leicester under the name Malaya, 
but this name has been considered by the present writer 
(1912) to be preoccupied by the Coleopterous genus Malaia 
Heller, and that being so, de Meijere’s name can be used 
for the genus. This is fortunate, for de Meijere’s work 
was much more detailed than Leicester’s, the latter author 
merely describing the external characters of a single male 
specimen caught in a bungalow. Shortly after de Meijere’s 
paper appeared, the genus was again described by Theobald 
(1909) under the name Grahamia, but this was corrected 
to Harpagomyia in the last volume of his monograph (1910). 
The genus may be characterised as follows :— 
Eyes contiguous or narrowly separated. Head clothed only 
with broad flat scales with rounded ends. <A pair of strong vertical 
bristles present, separated by a wide space from the orbital bristles. 
Clypeus rather long and narrow, somewhat tapering. Palpi alike 
in the two sexes, scarcely longer than the clypeus and in close 
contact with the base of the proboscis; jointing indistinct. An- 
tennae alike in the two sexes; flagellar joints all about equal in 
length and with moderately long basal hair-whorls. Proboscis 
rather short, hairy, directed backwards beneath the body when at 
rest; labella very large, thicker than the proboscis and nearly 
one-third as long, carrying two pairs of very long curled hairs. 
Mandibles and maxillae absent. Prothoracic lobes separated, com- 
pletely clothed with flat metallic scales, with bristles on front 
margin only. Mesonotal bristles developed on the sides only. 
Pro-epimeral and spiracular bristles both present, but few in 
number (1-3). No sternopleural or lower mesepimeral bristles. 
Postnotum bare. Male hypopygium: side pieces from 2 to 3 
times as long as broad, bearing scales on the dorsal surface, no 
apical lobes, basal lobes scarcely differentiated, bearing a tuft of
