complex structure, shown in figure; palpi of $ and $ very short 
and thin, almost thread-like, hidden beneath the elongated clypeus. 
Antennae of $ and 9 much alike. Thorax clothed with 
narrow-curved scales, and with a median line of broad flat scales 
in front, similar scales clothe the prothoracic lobes and occur just 
over them in a patch; these scales are of very marked form, 
being almost round. Scutellum clothed with short, broad, flat 
scales ; metanotum nude. Wings with scanty scales, moderately 
long and rather broad. The male antennae are verticillate, 
like the 9 • The genitalia seem normal, a long small clasper to 
each lobe. 
This forms a very distinct genus, which can at once he told 
by (1) the squamose characters, (2) the quaint proboscis, and (3) 
the elongated clypeus, which covers a greater part of the palpi. 
There is a curious complex structure at the apex of the proboscis 
in both sexes, which I have drawn as far as one can from the 
actual type specimens. Proper microscopic preparations alone 
can show the exact structure. 
I described this genus under the name Grahamia ,* but 
Meijere’s name has priority. Meijere’s species comes from 
Batavia and Semarang. Banks showed me a similar insect from 
the Philippines. They are Myrmecophilous -insects. There is no 
doubt that the African species described here comes in this 
genus. 
Harpagomyia trichorostris. nov. sp. 
Head metallic, pale pink and silvery; proboscis, etc., brown ; 
thorax deep blackish-brown with a broad median metallic mauve 
line in front; prothoracic lobes metallic white with mauve and 
rose reflections; silvery pleural patches; scutellum silvery. 
Abdomen smoky black with large apical silvery lateral patches. 
Legs brown, unbanded. 
9. Head clothed with flat scales, brown at the base, 
metallic pink, mauve and silvery white in front, forming a large 
patch passing between the eyes, flat white scales at the sides; 
clypeus brown, elongated; palpi brown, short and thin, just pro¬ 
jecting beyond the clypeus ; two chaetae arising from the base of 
the clypeus, one on each side ; proboscis brown, with long hairs 
along its whole length, the apical third swollen and elbowed
