THECLA. 



367 



Three specimens were taken at a high elevation to the north of 

 Ta-chien-lu. 



T. oenone resembles T. pruni 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 Thecla 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. tengstroemi, recently 

 included by Mr. Baker in the genus. 



Mr. de Niceville has recently (Butt. Ind. iii.) created the genus Cha-toprocta 

 for the reception of D. odata, Hewitson, the female of which has a large tuft 

 of densely packed pale ochreous-browu 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 herzi, Fixseu, Rom. sur L(jp. iii. p. 279, pi. xiii. fig. 4 (1887). 



Thecla phyllodendri, Staudinger, MSS., Elwes, Proc. Zool. Soc. 1881, p. 886. 



" Corpore fusco, capitis colore vix obscuriori, palpis supra et extrorsum uigris, intus pilis albido- 

 coeruleis, oculis albide circumductis, antennis nigris, albido annulatis, apice fusco, femoribus 

 cinereo-coeruleis, tarsis nigris albo-annulatis. 



" Alis supra fuscis ; posticis linea limbali tenui albide circumductis ; subtus pallidioribus, seriebus 

 punctorum nigrorum albide cinctis duabus parallelis in area limbali, fasci.aque fusca, marginem 

 anteriorem versus linea alba limbali obducta, ciliis fuscis grisescentibus." (FLvsen, I. c.) 



This species, Avhich 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 shining black. 

 Feeds on Pi/nis, and is full-grown in the middle of June. 

 Pupa light green, with a series of broad darker violet-brown lozenges on the back. 

 " Imago appears in J nly." 



Distribution. Amurland and Corea. 



Thecla thalia, sp. nov. (Plate XXX. fig. 15, c? .) 



Male. Upper surface uniform fuliginous brown ; male mark placed as in T. spini, and fairly dis- 

 tinct. Under surface rather paler ; primaries have a black discoidal spot encircled with
