ragged on both sides ; but from what remains of the anal patch, it appears to be of the same 

 character as that of T. arata). Body white, the venter creamy, the tarsi annulated with 

 black. Expanse of wings 1 inch 3 lines.

Fryer's figure of Z. {T.) signata is a very indifferent one and barely recog- 

 nizable ; he states that the species is not uncommon in Yesso. I have three 

 specimens from that island, which differ inter se and from the type, figured in 

 ' Aid,' in the character of the white basal marks on the under surface. 



Zephyrus quercivora. (Plate XXVII. fig. 15, ? .) 



Thecla quercivora, Staudinger, Rom. sur Lep. iii. p. 137, pi. vi. figs. 2 a, b (1887). 



" I received three bred specimens of this very interesting new species from Dorries, all of which 

 appeared to be females, and closely resembled the same sex of T. quercus on the upper 

 surface, but the pale blue of discoidal cell is continued beyond in the form of a streak in each 

 median interspace. The basal portion of the secondaries, especially the cell, is suffused with 

 blue, and the white-tipped black tail is distinctly longer than in T. quercus. The fringes are 

 dark, but in one specimen chequered, especially on the secondaries, with wbite. Under 

 surface ochreous slightly tinted with grey, differs from all other species of Thecla (from the 

 Palffiarctic or Indian Fauna) in having white markings at the base of the secondaries. The 

 large orange anal spot well defined. Antennae black, ringed with white, with less brown at 

 the tip than in quercus ; the pectus is clothed with bluish-white hair ; the whitf^ f'ct are out- 

 wardly marked with black ; the tarsi are white, ringed with black, and the abdomen is dark 

 above and yellowish white beneath. 



" The larva lives on oak, and is green witli brown spots along the back and sides. The first three 

 segments have some darker (blackish) spots, and are clothed with longer and thicker hair 

 than the others ; the eleventh segment has a somewhat remarkable conical process, which is 

 not familiar to me in the case of any other Lycaenid larva." {Staudinger, I. c.) 



Staudinger states that his description of quercivora is taken from three bred 

 examples of tlie female from Amurland, but his figure is said to represent 

 a male. 



Two female specimens, kindly lent to me by Mr. Grose Smith, one from 

 Icliang, Central China, and the other from Western China, probably Omei- 

 shan, agree with quercivora, except that the secondaries have more h\\\(i on 

 tli(! uj)])er surface. The figure of Z. quercivora agrees with tlio figure of 

 Z. sif/nafa in every ])articular but the character of basal marks on under 

 surface ; and as I find that these marks are inconstant in Z. signata, I am 

 disj)os('d to think that when more material is available it will be found that 

 qucrcimra is only a form of Z. signata. If Dr. Staudinger had been acquainted 

 with tlic latter species, he certainly would liave compared his quercivora with 

 it rather tb;ni ^vi(ll qnerniH.
