42. Tmethis hotsoni, sp. n. 
9 . Large, laterally compressed. Head narrow, prominent a bove pronotum ; 
front reclinate ; frontal ridge expressed above ocellum only, tot ally and abruptly 
disappearing below it ; fastigium of the vertex strongly sloping, longer than 
broaid, slightly widened anteriorly, transversely rugose ; eyes very prominent, 
oval ; occiput with an irregular median carina. Pronotum laterally compressed, 
especially so in prozona, which is considerably narrower and shorter than meta- 
zona ; prozona strongly tectiform, with median crista thick, deeply intersected 
by three transverse sulci, the hindmost of which is especially deep ; metazona 
as high, as prozona, thick, tectiform in its fore half, with thick elevated carina, 
which disappears on the apical third ; hind angle acute, rounded ; lateral lobes 
much higher, than long, with fore margin slightly sinuate ; lower margin sinuate 
anteriorly ; hind angle of lobes straight, rounded ; whole pronotum is covered 
with rather large, but not dense callous tubercules ; metazona rugulose. Eiytra 
very long, extending far beyond hind knees. Hind wings a little shorter than 
elytra. Mesostemal lobes nearly triangular, their inner margins being strongly 
oblique ; interspace much broader, than long. Metasternal lobes widely sepa- 
rated. Hind femora elongate, granulose, with upper margins slightly undulate ; 
lower margin straight. Second abdominal segment raised posteriorly in a rather 
thick median protuberance. 
General coloration whitish-grey ; pronotum feebly brick-reddish. Elytra 
ochraceous-grey, with indistinct grey marks. Wings light greenish-blue, with 
a 4-5 mm. wide black band, which starts from the middle of fore margin and 
runs straight backwards to the hind margin but does not reach it by about 5 mm., 
suddenly turning under a straight angle inwardly and reaching the inner margin ; 
two apical lobes brown. Hind femora coeruleous beneath, light blue inwardly, 
with inner knee lobes dark blue. Hind tibiae with inner and upper surfaces 
blue, with a pale ring near the base and a red apical spot. Abdomen pale 
with hind margins of basal tergits blue-black.

The female of this species has been taken by Lt.-Col. J. E. B. Hotson inMand, 
Baluchistan, 29, iv. 1916, on sand ; it bears the remark, ‘‘plentiful,” but only one 
rather damaged specimen has been included in collection sent to British Museum 
by the Bombay Society. The species belongs to the group of T. gibber, St., 
but is bigger, more constricted laterally, with longer elytra, than any other 
known species, and is also easily recognised by narrow band of wings, bent under 
a right angle.
