500 Mr. F. W. Edwards on 
positor is not exserted in any of the specimens, and cannot be 
seen when they are in the dry state ; 1n the mounted specimen, 
however, it is conspicuous and is about half as long as the 
entire abdomen. Legs stout, clothed for the most part with 
dark brown scales ; on the apical half of the hind tibie and 
the whole of the second hind tarsal joint, however, these 
scales are light greyish. ‘The empodia are slightly longer 
than the stout black claws. Wings appearing blackish 
owing to their dense hairy covering, the tips of the veins 
somewhat darker than the remainder of the wing. alteres 
blackish, base of stalk yellowish. 
Length of body 3 mm. ; antenna 2°2 mm.; wing 2°8 mm. 
Pupa.—Rather dark brownish in colour. Cervical arma- 
ture as in the diagram, the anterior edges finely serrate. 
Four facial teeth ; one large one in front and a group of 
three rather smaller ones behind, two of which are some 
distance in front of the third. The anterior half of each 
abdominal segment bears numerous irregularly arranged back- 
wardly directed spines, while situated at about two-thirds of 
the distance across each segment is a regular transverse row 
of about 20 spines. 
Gall_—-Glandular, on the surface of the stem of an un- 
determined plant; very much resembling that figured by 
Kieffer for Daphnephila glandifer (Gen. Ins. Cecid. pl. 11. 
figs. 2 & 3), except that the individual galls are quite separate 
at the base ; in size the galls are 4-6 mm. long by 2-3 mm. 
broad, and on the piece of stem sent, which is only 3 in. x 
34 in., there are about eighty galls. Only a single larva 
occupies each gall; pupation occurs within the gall, and the 
pupa emerges by boring a more or less circular hole at the 
apex.

Palpomyia flagellata, sp. n. 
Head shining black, front fairly broad, the eyes separated 
by about the width of the second antennal joint. Palpi and 
proboscis dark brown, the latter a little shorter than the 
vertical diameier of the head. Antennas long as the whole . 
body ; first seapal joint small, second larger, nearly globular ; 
flagellar joints all cylindrical, the first about ten times as 
long as broad, the next nine all about equal in length, five 
times as long as broad, last four more elongate and more 
densely haired than the first ten, which have each a few stiff 
hairs near the base and apex. The scape of the antenne is
