mososternal interspace about one half again as broad as one of the lobes. Metas- 
tornal interspace sub-equal in width to one of the mesosternal lobes,  Blytra per- 
footly lateral, lance-shaped, extending a little beyond the hind margin of the me- 
tanotum ; wings shorter than elytra, Tympanal organ open, but the tympanum 
seems to be not membranaceous, and the organ is probably not functioning, 
Abdomen distinetly conical, because the mesonotum, metanotum and the first 
abdominal tergite are thickened ; a linear median keel runs all through the 
abdominal tergites, gradually lowering backwards, Fore and middle legs short. 
Hind femora not reaching the apex of the abdomen, moderately thickened basally 
and gradually narrowed apically, Hind tibie with nine outer and eleven inner 
apines, without an outer subapical spine ; apical spurs short, Valve of the 
ovipositor short, rather thick, recurved apically ; the lower ones with obtuse 
tooth,

9. Greyish-ochraceous (has been preserved in’ spirit)” with greyish and 
brownish dots, Face rugulose and spotted with brownish. Antenne with alter- 
nate palo and brownish rings. Fastigium and occiput spotted with brownish, 
Pronotum in the prosona rugulose, with brownish spots, in the metazona densely 
punetured, ochraceous ; hind margin with brownish streaks along it. Elytra 
of the general coloration, with indefinite greyish spots, Legs darker than the 
body, marmorated and fasciated by brown, Hind femora with two fooble dark 
fasciw on the upside, and with two still more indistinet oblique fascivw on the 
outer side ; the second (subapical) upper fascia extends also in on the inner side 
where it is somewhat better expressed ; the knees are brownish all over, with the 
lobes paler, brown-spotitied. Hind tibie pale with the base, a fascia before the 
middle and the apical fourth part, brownish ; spines and spurs with brown apices. 
Length of body 18 mm, ; pronotum 4 mm. ; elytra 2°5 mm. yhind femora 9 mm. 
Deseribed by a female from Gyangtse, 18,000 feet, June, 1904, Tibet Expedi- 
tion, H. J. Walton ; three paratypic females are from the same locality, 
The inseet is somewhat alike in its habitus to a Sphingonotus, but it lacks the 
most characteristic feature of that genus—the constriction of the pronotum ; the 
undeveloped elytra and thickened mesonotum and metanotum give it an alto- 
gether peculiar appearance, Though the specimens are all rather discolored by 
the spirit, it seems that their coloration when living has been essentially the 
same as it is now,

&. Resembling in its habitus to the New Zealandian genus Paprides, Hutt, 
and the Indian Pileolwm, Bol, 
Antenne somewhat compressed, a little longer than the head and pronotum 
together, Head not prominent above the pronotum and not thicker than that. 
Face strongly oblique ; frontal ridge elevated, in profile almost straight, flat, 
with a feeble impression below the ocellum, with the margins straight, feebly 
divergent downwards, very obtuse but nearly reaching the clypeus, Fastigium 
of the vertex forming distinet angle with frontal ridge, distinctly prominent 
before the eyes, but slightly shorter th@n broad, obtusely triangular ; its surface 
very slightly impressed, with somewhat raised margins and with a low median 
oarinula, which begins from the apex, but disappears in the occiput ; vertex be- 
tween the eyes twice as broad as the frontal ridge between antenna, Eyes 
irregularly oval, their vertical diameter exceeding the horizontal one by about 
one-third of the latter; hind margin strongly rounded ; fore margin almost 
straight ; both upper and lower angles subacute. Pronotum above flattened ; 
median keel low, but very distinet, straight in profile, cut by the typical sulcus ;
