SECOND YARKAND MISSION. 
less strongly emarginate at cacli side as the shoulder is more or less advanced, which, in some 
examples, is as strongly so as in Diesia karelmi, Eisch. ; usually with an angulate depression 
behind the scutellum ; variously granulose, each granule bearing a setiform hair, which is 
longer or shorter, black or fuscous brown ; these granules are minute on the disc, larger 
(almost tuberculiform) at the sides, more or less distinctly seriately arranged down the elytra, 
moderately intervalled both longitudinally and transversely; at two-thirds the width of the 
elytron, from the suture, is placed a more or less distinct row of rather larger and more closely- 
placed granules, with sometimes indications of two others, one between it and the suture, the 
other between it and the margin ; the margin is closely, sub-serrately granulose, or tuberculose : 
starting from the humeral angle a more or less flexuous elevated line obliquely traverses the 
epipleura ; this line is always granulose at the base, and sometimes more or less minutely inter- 
ruptedly so along its entire length ; above this line the epipleura is sparsely granulose, the 
granules somewhat large at the base and apex, minute and more remote between ; the part of 
the epipleura below the line is more or less smooth, except at the apex, where are a few small 
granules. Underside and legs moderately, closely, and uniformly (a little largest on the femora) 
granulose, and clothed with a fine cinereous pubescence : the four hind tibiae are hispid, and 
outwardly fringed with long fuscous hairs ; the front tibiae are strongly triangular, the outer 
apical angle dentiform, the outer edge finely numerously spinose or dentate 1 ; tibial spurs long 
and powerful, the inner one considerably longer than the outer : the four hind tarsi are fringed 
with long fuscous (sometimes becoming a little rufescent) hairs at the sides, and with a tuft of 
bright fulvous hairs at their tips beneath: antennae black, clothed with short hairs, the 
last joints ferruginous and naked, except for a few long setae arising from near their base ; 
last joint short, free, acuminate at apex : prosternal process horizontal, feebly convex, granu- 
lose, more or less prominent and rounded behind. 
Length 7 to lines ; width of elytra across the middle, 3- 1 - to 4| lines. 
Kashgar to Kogyar. 
A variable species, and showing affinities with the genus Diesia. 
Tkigonoscelis lacebta. 
Ovoid, black : head large, strongly transverse, a little tomentose, 3 feebly remotely punc- 
tured, granulose behind: epistoma broadly emarginate in front, angles distinct: labrum black, 
middle of front emarginate, angles rounded, distinctly punctured : prothorax rather strongly 
transverse, quadrate, depressed on the disc, and rather broadly so down the median line, apex 
very faintly sinuate, angles somewhat prominent and acute ; sides moderately rounded ante- 
riorly, sinuately contracted behind, base not wider than apex, sinuate, moderately so at the 
middle ; hind angles slightly outwardly directed ; irregularly covered (sparsely on the disc) 
with rather large, round or oval, flattened tubercles, these largest on the disc, smaller and closer 
at the sides, the interspaces having a few scattered minute pointed tubercles : scutellum triangu- 
lar, sub-petiolate, placed on the mesonotum : elytra oval, regularly convex, gently declivous 
behind, apex a little produced and (conjointly) founded: on each elytron five irregular 
1 It is really tubercled with spines arising from their summit ; and when these spines get rubbed or broken off the ed^e appears 
to be dentate. ° 
Most probably, in fresh examples die entire surface is covered with a dull yellowish tomentum.
