262 Mr. F. W. Edwards on 
from the North-American continent. The new species — 
differs from DL. minimus, Alex., im coloration, in the longer 
radial sector, and in the absence of a distinet M—Cu cross- 
vein ; it resembles Alexander’s species in the long peticle of 
the cell m. 
The coloration of this species is so very different from that 
of a normal Tipuline, and so remarkably like that of Hriceera . 
rubriceps (described above, p. 253), that it is almost im- 
possible to believe that the resemblance between these twe 
can be merely accidental. Possibly both may be mimics of a 
hymenopteron. 
Shinten, 400 ft. (7. Shiraki), 1 3. 
Longurio fulvus, sp. n. 
The British Museum possesses two females of another very 
distinet species of Longurio from North China (Coll. Fortune, 
purchased from Stevens in 1856). It will be convenient to 
describe them here under the above name. 
Body wholly dull orange-ochreous, with the following 
exceptions :—Palpi black ; flagellum of antenne dark brown ; 
last abdominal segment and ovipositor black ; a rather narrow 
interrupted black median line on the venter; legs dark 
brownish; wings brownish-tinged, but not so dark as those 
of L. rubriceps, hence the stigma is more conspicuous. Struc- 
tural characters very similar to those of L. rubriceps, but the 
third, fourth, and fifth antennal joints are more oval ; Sc, is 
more oblique, the cell M, is about twice as long as its petiole ; 
and the tarsi are not quite so long (this last character may 
vary with sex). In one specimen Cu, is just in contact with 
Ms, in the other a distinct M—Cu cross-vein is present. 
Length of body 18 mm. ; wing 18 mm,; hind tibiall mm. ; 
first hind tarsal joint 18 mm. 
BRITHURA, gen. nov. (Pl. XII. figs. 10-12.) 
Antenne not longer than the thorax, 14-jointed, the flagellar 
joints with long verticillate hairs at the base, two above and 
one below. Rostrum as long as the head, with distinct nasus. 
Fourth palpal joint thin, as long as second and third together. 
Front with a sharp-pointed conical elevation just above the 
antenne. Body very stout; ninth abdominal tergite in the 
male turgid, claspers rather narrow, twisted, projecting 
beyond the ninth tergite and conspicuous from above. Legs 
not greatly elongated, first tarsal joints considerably shorter 
than the tibiz ; femora without apical comb ; claws with a 
small tooth near the base ; empodia well developed. Wings 
broad ; a slight projection on the costa above the stigma, a
