afford no distinctive characters ; as, however, it can be separated by its darker colour 

 from A. sylvatica, we retain the name for the Chinese form.

Adopcea neevdlata. 



Pamphila nervulata, Mabille, Ann. Soc. Ent. Fr. 1876, p. lvi. 



Adopcea nervulata, Leech, Butt. China &c. p. 592, pi. si. fig. 3, $ (1892-94). 



The insect here dealt with is that described and figured by Leech ; whether it is the 

 true nervulata of Mabille remains doubtful, since the specimens do not possess the 

 " striga anticarum sexuali nigra filiformi " mentioned in the original description.

Differs from typical leonina in wanting a sex-mark in the male and being rather 

 more suffused with black. The male genitalia are similar to those of A. leonina, but 

 so also are those of A. tenebrosa.

This genus and the four which succeed it form a natural group well distinguished by 

 the form of the palpi, which have the second joint appressed and densely scaled, and 

 the third joint porrect, long, and slender, about half as long as the diameter of the eye. 

 In most of the species of this genus the club of the antennas is as long as or longer than 

 the shaft. Vein 5 in the fore wing straight, its base equidistant from veins 4 and 6 or 

 (in mahintha and ionis) a trifle nearer to vein 6 than to vein 4. Vein 3 of hind wing 

 arising close to the end of the cell. 



The species known to us may be distinguished as folloAvs : —
