Descriptions of sixty-eight new species of oriental diptera 
are given in the present paper, and those of four new genera. 
Four previously known species are redescribed and four European 
species introduced to the Oriental fauna. The Indian Museum 
possesses all the types of the new species except one or two in my 
own collection. A number of the types of new species obtained 
by Dr. A. D. Imms have been very kindly presented by him to 
the Museum collection. 
New material in the Indian Museum in Syrphidae and 
Acalyptrata will form the subject of two subsequent papers. 
CHIRONOMIDAE. 
Ceratopogon lignicola, mihi, sp. nov. 
@. Western Himalayas. Long. 12 mm. 
Head.—Black. Eyes distinctly separated above, reniform. 
Antennae blackish with very long dense black hair (which in 
certain lights appears paler), except on the ultimate two joints, 
these latter bearing only a little short greyish pubescence. 
Thovax.—Black, with very long black stiff hairs laterally and 
on the posterior part and scutellum. Anterior half of dorsum with 
closely placed semi-recumbent very short bright yellow hairs. 
Hind border of scutellum with a row of long stiff bristles. 
A bdomen.—Blackish, with long blackish hairs (which give 
greyish reflections, viewed from certain angles). Genital organs 
moderately large, concolorous, pubescent; each clasper with a 
very long strong dorsal bristly hair, posteriorly directed. 
Legs.—Blackish, with long brownish hair on femora and tibiae; 
knees brownish yellow; tips of tibiae and of tarsal joints more or 
less brownish yellow. Fore metatarsi a little longer than 2nd joint. 
Wings.—The 3rd longitudinal vein ends a little before middle 
of wing; “‘intercalary ’’ (Kzeffer)* vein, simple, ending opposite tip 
of upper branch of 5th vein; anterior cross vein oblique; 4th 
longitudinal vein forked a short distance beyond anterior cross 
vein, the branches gently divergent throughout their length; 5th 
vein forked widely at or just beyond middle of vein, upper 
branch in a line with basal part except for the very gentle 
curve the whole vein takes; 6th vein close to and parallel to the 
* I temporarily follow Kieffer in the use of this term, not having studied 
Chironomidae sufficiently to speak with decision, but there is no vein of this 
hame accepted amongst dipterologists,
