SECOND YARKAND MISSION. 
which, may be sexual, the more strongly punctured, &c., being the male. In the North American 
representatives of these genera the male is distinguished by having on the first ventral segment 
a round patch of short, silky-golden hairs ; at least it is so in the genera Triorophus and 
Stibia. To this latter genus Dr. Horn denies the presence of a tooth on the upper surface of 
the mandible. This is evidently a lapsus, as so keen and accurate an observer could not have 
failed to detect it. With some remarkable exceptions (hereafter noticed), I have found this 
tooth existent in all the numerous genera I have dissected, and, I believe, it will be found all 
but universally present in this sub-family. 
Syachis himalaictjs. 
Black, moderately shining; underside and legs reddish-brown, antenn® and palpi paler : 
labrum entire in front : head rather strongly but not closely punctured ; strongly wrinkled 
above the eyes, the wrinkles extending nearly to the crown ; epistoma prominent, strongly 
separated from the antennary orbits, slightly hollowed out at the sides, broad and truncated 
at apex ; superior tooth of right mandible sub-acute : prothorax transverse, a little narrower 
in front than behind, subangulately rounded at the sides, front angles prominent and acute ; 
strongly and rather closely punctured at the sides, more feebly so on the middle : elytra briefly 
oval, convex, abruptly declivous behind, produced at apex, shoulders rounded ; the surface a 
little uneven, covered, but not densely, with rather large but more or less shallow punctures, 
the epipleur® rather strongly muricately punctured : underside ratber densely covered with 
large rounded punctures : flanks of prothorax very coarsely longitudinally rugose and con- 
fluently punctured : epipleural fold more or less, but never strongly, muricately punctured. 
Length 3^ to 4 lines. 
Dras, Kargil, and Leh. 
Syachis picicornis. 
Black, moderately shining ; underside of body black, legs and antennae piceous : labrum 
feebly emargiuate in front: head moderately, not closely, and uniformly punctured, not 
wrinkled at the base, the punctuation a little coarser and confluent above the eyes ; epistoma 
feebly separated from the antennary orbits, being almost continuous with them, broadly rounded 
in front ; superior tooth of right mandible obtuse : prothorax narrower in front and more 
feebly emarginate than in the preceding, front angle not so prominent ; sides rounded behind 
the middle ; very finely and sparsely punctured on the disc, more strongly and closely so at 
the sides : elytra oblong, shoulders not rounded, gently declivous behind, the punctuation 
feebler than in the preceding, the epipleurse not muricately punctured: epipleural fold 
smooth ; punctuation of underside much feebler and less dense than in the preceding. 
Length 3^ to 4 lines. 
Dras, Kargil, and Leh. 
Ascelosodis, Redtenb., Reis. Novar., p. 117. 
Prothorax and elytra more or less ciliate at the sides. 
Base of prothorax not lobed in the middle. 
Elytra densely rugose punctate.
