the genus Hineis. 471 
only recently identified from specimens sent me by Dr. 
Staudinger, and which agrees exactly with one of the 
cotypes which I had previously received from the St. 
Petersburg Museum, and had treated as an abnormal 
form of urda. The type came from near Kiackta, and it 
has more recently been found by Graeser in marshy 
larch-woods at Pokrofka. 
(4. fulla.—This species, which was described by Evers- 
mann from the mountains round Lake Baikal, has more 
recently been taken by Haberhauer on the southern 
slopes of the Tarbagatai (see Staudinger, Stett. Ent. 
Zeits., 1881, p. 271). The latter considers it as a form 
of norna, from which, however, it may always be dis- 
tinguished by the clasp-form It is very distinct in 
appearance from typical norna, but it might easily be 
confounded with small pale specimens of the latter, of 
which I have one from South Lapland, and have seen 
others taken by Schoyen on the Porsanger fiord, par- 
ticularly when these have the sex-mark almost obsolete ; 
but the two species may be readily separated on a com- 
parison of the clasp-form, which in some cases may be 
effected without dissection, if some of the long scales at 
the apex of the abdomen be removed, either by scraping 
with a pin, or rubbed off with a moistened camel’s-hair 
pencil, when it may be seen that the clasp in norna is 
suddenly narrowed about the middle, the apical part 
being about one-third as wide as the basal part ; the apex 
(viewed from the side) is narrowly rounded, and the 
teeth on the upper edge extend backward but a little way 
from the apex ; in fulla, however, the clasp is gradually, 
not suddenly, narrowed, the apex (viewed from the side) 
appears obliquely subtruncate, and the teeth on the 
upper edge extend almost to the base of the clasp, as 
visible in sitw (see fig. 4). 
(#. hora. — This species, described from the Alai 
Valley of Eastern Turkestan, where it was taken at 
11,000 ft. elevation by Grum-Grshimailo, and afterwards 
more numerously by the same gentleman in the southern 
part of the Thian-shan Mountains, is very like fulla ; but 
may be separated not only by the differences given in the 
conspectus (vide infra), but by the different shape of the 
clasp (see fig. 7). 
Compared with my specimens, which were taken by 
M. Grum-Grshimailo at Thian-shan, the figure of this
