ZEPirrRFS. 369 
Eeferring to this species, M. Grum-Grshimailo (Rom. sixr Lep. iv. p. 387) 
says that in Central Asia two forms occur — the type, which inhabits tlie 
prairies, principally at an altitude not exceeding 3200 feet ; the other form, 
which he describes as var. carlonaria, and figures on pi. viii. fig. 9, inhabits 
the sub-alpine zone at about 9000 feet. 
The only form of this species occurring in China appears to be var. davidi, 
and, so far as I am aware, the specimens taken by I'Abbe David are the only 
known examples from that country. 
Grum-Grshimailo (Hora3 Ross. 1891, p. 452) describes two forms of the 
species from North-eastern Thibet — var. tangutica, from the Dshachar Moun- 
tains, and var. iliensis, from Suidun. Judging from the description, the 
former seems to come very near to var. davidi, Oberthiir.

" FoEE WING large, subtriangular ; costa regularly arched, apex subacute, outer margin slightly 
convex or straight, inner margin straight ; costal nervure reaching to about half the length 
of the wing, terminating just opposite to the apex of the discoidal cell, first subcostal nervule 
given off from the subcostal nervure at about two thirds the length of the discoidal cell ; 
second subcostal nearer to the apex of the cell than to the base of the first subcostal, third 
subcostal originating rather nearer to the apex of the wing than of the cell ; upper discoidal 
nervule given off from the .subcostal some distance beyond the apex of the cell ; middle disco- 
ceUular nervule nearly straight (slightly concave), upright, lower discocellular longer than 
the middle discocellular, concave, slightly outwardly oblique ; second median nervule given 
off before the end of the cell ; submedian nervure straight. 
" Hind wing large, broadly ovate, the extremity of the first median nervule elongated into a fine 
tail, variable in length (very short in the European Z. cjuercu-i, Linnveus, and entirely absent 
in Z. lihasia, de Niceville), and the anal angle produced into a larger or smaller anal lobe ; 
first subcostal nervule arising from the subcostal nervure rather near to but before the apex 
of the cell ; discocellular nervules nearly iu one straight Une, outwardly oblique, the upper 
rather shorter than the lower ; second median nervule arising just before the lower end of the 
discoidal cell. 
" Eyes hairy. 
" Antennce clavate, the club very gradually formed. 
" Palpi somewhat long, obliquely porrected, the third joint horizoutal, the second joiut very 
bristly beneath, third joint naked. 
" Laeva short, thick, onisciform, tapering towards each end, clothed with fine short hair. 
Piqya short, thick, rounded." {de Niceville, I. c.)
