Genus 28. DEINOCERITES, Theobald. 
; BRACHIOMYIA. Theobald. 
(Mono. Culicid. II., p. 215, 1901 (Deinocerites), and p. 343 (Brachiomyia). 
A great deal of fresh material has been received from Dr. 
Grabham dealing with the genus Deinocerites. This necessitates 
remodelling the genus ; the specimens from which it was described, 
although apparently perfect, have proved not to be so, and the 3 
sent with the ?’s wasa ¢ Culex and not a ¢ Deinocerites. 
The ¢ is of Aedes type, and thus the genus comes in the 
Aedeomyinae and not the Culicinae. The notes on the life-history 
have nearly all been sent me by Dr. Grabham. The genus 
Brachiomyia (Mono. Culid. IT., p. 343) was separated from Deino- 
cerites on account of the densely-scaled antennae and the different 
relative length of the antennal joints. Recent perfect material 
has shown that the antennae of Deinocerites are also scaled, 
so that the genus Brachiomyia must sink under Deinocerites ; 
this shows the importance of describing these insects only from 
perfect material. 
Characters of the Genus. 
Head clothed with narrow-curved and upright forked scales ; 
thorax and scutellum with narrow-curved scales ; palpi short in. 
both sexes, scaled, slightly longer in the ¢ than in the ?; 
antennae moderately long in the ?, the basal joint nude except 
for a few hairs on its inner side, second joint very long, equal in 
length to the three following joints or nearly so, scaly, other 
joints finely pilose ; in the ¢ the antennae are very long, filiform 
and pilose, longer than the whole body, the second joint long, as 
long as the two following joints; the joints gradually become 
shorter towards the apex of the antennae, the first four or more 
joints of the flagellum are scaly ; in life the apical joints of the
