is not possible to settle the matter finally Init it seems more reasonable at present to refer 

 all these toreal forms to grocnlandicus. It is clear from l-^kblom's map that the latter sub- 

 species, as here understood, is separated from the other forms by a wide intervening 

 subboreal zone in which the species is absent. 



The parameres of the West (ireenland specimen are iclentieal in shajie with those of the 

 North Haven specimens, though the angular prominence is a little more setose, a character 

 that varies in parameres of insects from the same locality in Indian Tibet. There can be 

 no doubt therefore that ^^rocnlaitdicus is rightly referred to this species. 



e. A^. gniDiinicohi ( Klti. I . This species is easily distinguished by its coloration from the 

 preceding, for the longitudinal veins of the corium are hardly, if at all, infuscated and the 

 general coloration is paler. In shape gni)}iinicola is more elongate than thyiiii, but the corial 

 margins are posteriorly more strongly and more regularly rounded than in cricac. The pro- 

 notum is without a transverse black band obscuring the bases of the apodemes, which are 

 at most surrounded with an intcrru])ted black suffusion. The vertical margin sjjot is very 

 feebly developed. 



The genitalia of a sjiccimcn from I'orto d' Ischia, on the island of Ischia. ltal_\-, were 

 studied. The dorsal angle is very feebly emarginate and '.be ventral keel moderately devel- 

 oped (Plate VIII, figs. 20, 21). 



It is clear from the above that lliyiiii. cricac, and gniiiiinicola, three very closely allied 

 but adequately defined species, all show differences in their genitalia, while the various forms 

 here grouped under cricac show no such differences, thus justifying the present arrangement. 

 I have not been able to examine the genitalia of cyiiioidcs, a most distinct species with very 

 long subparallel elytra. 



The material collected l)y the Yale North India E.xpeditioii was obtained from five 

 localities, as enumerated below. Measurements and notes on the individual specimens are 

 also set out in Table I. It will be seen that the material from the lowest locality is prac- 

 tically identical in form and color with typical A', c. cricac, while from the highest a rather 

 distinct new form w'as obtained which is described below as alticola subsp. n. From the 

 intermediate localities series were obtained which appear to combine the characters of all the 

 Central Asiatic forms known, viz., cricac s. str., obscuratu^ and alticola. 



A. Leh. 1 $ Residency Garden. 19 Sept., 1932, altitude 3506 m. Parameres typical of 

 species. This specimen may lae considered as a very slightly atypical member of A^ c. cricac 

 (PlateVTII, fig. 10). 



B. Tsak-shang, N. of Tso Moriri. 2 9 9. 31 Aug., 1932. altitude 4872 m. These 

 specimens are comparable to some of the 9 9 from the next locality; they are ])robablv 

 nearer to A', c. cricac than any other form.

 altitude ^\Mi in. 'ihe specimens numbered 1 and 2 are very close to (ihsciiraliis. The third 



i is practically typical ('. rr/cat', though very small. Specimen 2 (Plate \lll. lig. 11) is 

 slightly wider than the others, so approaching alticola. The females are rather variable in 

 width, but none .show the coloration of obscitratits. 



D. Kyang-La, Koh Lungpa valley. 2 S $. 9 July, ].':>:^2. altitude .5100-5200 m. 

 These two specimens are both here referred to alticola; the darker one is rather similar to
