56 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. 



STACHIS HIMALAICTJS. 



Black, moderately shining ; underside and legs reddish-brown, antennae 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 epipleurse rather strongly muricately punctured : underside rather 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 emarginate 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 epipleurae not muricately punctured : epipleural fold 

 smooth ; punctuation of underside much feebler and less dense than in the preceding. 



Length 3^ to 4 lines.
