THECLA. 367 
Three specimens were taken at a high elevation to the nortli of 
Ta-chien-lu. 
T. cenone resembles T. priiid on the under surface, but the white lines are 
straighter and have a well-formed W before terminating on abdominal 
margin ; there is much less fulvous colour on marginal area of secondaries, 
and no trace of this colour on primaries. It also agrees with T. mera in 
some characters, but the sexual mark on primaries is less conspicuous, and 
the tails of secondaries are more slender than in either of those species. 
The only other species of Theda in which I have observed the anal patch 
of velvety-black hairs referred to above are T. acacice, a species which I 
believe has not been recorded from Eastern Asia, and T. feivjstrn'mi, recently 
included by Mr. Baker in the genus. 
Mr. de Niceville has recently (Butt. Ind. iii.) created the genus ChcHoprocfa 
for the reception of D. oclata, Hewitsou, the female of which has a large tuft 
of densely packed pale ochreous-brown hairs at the extremity of abdomen. 
Excepting that each has this anal tuft of hairs, the three species referred to 
above have few characters in common. 
Thecla herzi.

Thecla phijllodendri, Staudinger, MSS., Elwes, Proc. Zool. Soc. 1881, p. 880. 
" Corpore fusoo, capitis colore vix obsouriori, palpis supra et extrorsum nigris, intns pills albido- 
coeruleis, oculis albide circumductis, anteunis nigris, albide annulatis, apice fusco, fomoribus 
cinereo-coeruleis, tarsis nigris albo-annulatis. 
" Alls supra fuscis ; postieis linea limbali teniii albide circumductis ; subtus pallidioribus, seriebus 
punctoruni nigroruni albide cinctis duabus parallelis in area limbali, fasciaque fusca, marginem 
anteriorem versus linea alba limbali obducta, ciliis fuscis griseseentibus." (FLvsen, I. c.) 
This species, which Fixsen described from the Corea, has since been met 
with in various places in Amurland. 
Graeser (Berl. ent. Zeit. 1888, p. 72), describes the early stages as follows : — 
" Larva. Velvety uniform dark green, beneath rather paler blue-green ; head shinino- black. 
Feeds on Pyi-us, and is full-grown iu the middle of June. 
" Pupa light green, with a series of broad darker violet-brown lozenges on the back. 
" Imago appears in Jul}'." 
Distribution. Amurland and Corea. 
Thecla thalia, sp. nov. (Plate xxx. fig. 15, c? .) 
Male. Upper surface uniCorm fuliginous brown ; male mark placed as in T. spini, and fairly dis- 
tinct. Under surface rather paler ; primaries have a black diseoidal spot encircled with 
3c2
