A little smaller than C niannerheimi, Gebl., lighter in 

 colour, especially legs and antennae, surface more shiny. 

 Head much more sparsely punctate, with more prominent 

 eyes and deeper foveas ; prothorax more transVerse, with 

 wider marginal channel and more obtuse hind angles, sur- 

 face less and not confluently punctate ; elytra shorter and 

 a little more convex, sides more rounded, basal border 

 strongly sinuate on each side, apex hardly truncate, striae 

 much finer, 7 less evident near apex, surface more finely 

 punctate, and with shorter pubescence.

XXXII. — -Coleoptera of the Second Mt. Everest Expedition, 

 1922.— Part II. Heteromera. By K. G. Blair, B.Sc, 



F.E.S. 



The total number of Heteromera collected by the Expedition 

 of 1922 amounts to 139 compared with 17 obtained last 

 year, though the number of species is only 7 compared 

 with 4 (or possibly 5) of last year; only one of these, 

 Mylabris przeivalshyi, was obtained in both years. The rest 

 of the Heteromeia all belong to the family Tenebrionidse, 

 and all the species are apparently undescribed, though 

 belonging either to genera that are peculiar to the moun- 

 tainous regions of Central Asia or to groups of species 

 characteristic of this region in more widely Palsearctic 

 genera. They were all captured by Dr. T. G. Longstaff, 

 the Medical Officer of the Expedition, the Tenebrionidse all 

 under stones, and, except the Gnaptorina, all in the vicinity 

 of the Base Camp, Uongbuk, Thibet, at an elevation of 

 16,500 ft., i. e., about 2000 ft. lower than last year's locality 

 and about 2 miles further from Everest, but with an 

 identical aspect. Probably the great difference in the 

 material secured in the two years is due largely to this 

 method of collecting, though the early date, 16th to 20th 

 May, about two months earlier than last year, no doubt 

 accounts for the comparative absence in 1922 of flower- 

 frequenting species — indeed, Dr. Longstaff informs me that 

 there were no flowers.
