new and little-known Tipulide. 263 
distinct though shallow emargination at the apex of Cu, ; 
anal extended some way beyond the base of the basal cells. 
Sc, distinctly reaching costa; Sc short, oblique, near tip of 
Se,. Rs rather short; R, present; R; nearly straight ; 
R,,; curved downwards, ending below the tip of the wing. 
Kt-M ecross-vein absent or quite short. Cell Ist M, penta- 
gonal; cell M; petiolate, the petiole hardly half as long as 
the cell. 
Genotype, Brithura conifrons, sp. n. 
This genus is distinguished from Zipula chiefly on account 
of the presence of Sc, which terminates distinctly in the 
costa. ‘The combination of a number of other minor pecu- 
liarities gives the insects a very distinct facies. The venational 
character of the presence of Sc; is not found, so far as I am 
aware, in any species of J’pula or in the related genus 
Ctenacroscelis ; it does occur, however, ina number of species 
of Holorusia and Macromastiz, but these genera are, in my 
opinion, less closely related to Lipula, since they are devoid 
of verticillate hairs on the antenne. 
Brithura conifrons, sp.n. (PL. XII. figs. 10 & 11.) 
Head dark velvet-brown, a light V-shaped mark between 
the frontal cone and the base of the antenne ; some short 
dark hairs above and long ones below. Rostrum uniformly 
dark brown. Palpi blackish, third joint lighter. Antenne : 
first joint elongate, dark brown, black-haired ; second joint 
cup-shaped, lighter brown, bare. Third joint nearly cylin- 
drical, contracted at the base, blackish, about half as long as 
the first. Remaining flagellar joints (except the last two) all 
nearly equal in length to the third, dorsal surface straight, 
with a slight basal enlargement, ventral surface evenly 
convex ; pubescence very fine, not. more than one-sixth as 
long as the width of the joints ; the three long verticillate 
hairs are almost three times as long as the joints, and there 
are, in addition, one or two shorter hairs at the base of each 
joint on the inner side. ‘Twelfth joint a little shorter than 
the eleventh, thirteenth more than half as long as the twelfth ; 
the hairs on these two joints all about equal in length. 
Thorax almost uniformly dark velvet-brown; mesonotum 
with three lighter brown stripes; front edge of hypopleuree 
silvery grey when seen from behind. Scutellum, postnotum, 
and sides of prescutum rather thickly clothed with dark hair. 
Abdomen dark brown, slightly shining, hind corners of tergites 
grey; pubescence short, black; eighth and ninth segments 
and genital appendages wholly orange, with orange pubes-
