Eastern Pier idee. 395 



sidered as one abundant and variable species, which has become 

 segregated into several forms, which may be divided into two 

 pretty well-marked groups. 



There has been great confusion about this species. Drury's is 

 the best and most recognizable figure I have seen. The Linnaean 

 description is so imperfect that the name ought perhaps not to be 

 retained, but it has been so generally applied to some of the 

 forms of this species that I think it better to keep to it.

Cr., Dru.). 



Male. — Costa much curved, hind wings subtriangular. 



Above, like T. pi/rene, but the transverse black band always 

 touches the discoidal spot of the uppers. Beneath, yellow, faintly 

 speckled with black ; on the hind wings a row of six or seven spots, 

 of which one on the inner margin, as well as the third and fourth, 

 are larger and have pearly or violet-white ocelli. 



Female, — Very like the male, differing only in the orange patch 

 being smaller and less regular, and having two black spots on its 

 lower part. Beneath, as in the male, but the spots are more dis- 

 tinct, and almost all have white ocelli. 



Expanse of wings ($ and $ ), 2 inches.

Variety A. — Is rather clearer in colour, has the upper wings 

 rather more acute, and a trace only of border on the hind wings 

 in both sexes. Beneath, of a richer chrome-yellow tint. The 

 female generally as in the type, but sometimes almost white as in 

 the extreme form of T. pyrene $ .

jHa6.— Sylhet, Darjeeling (Coll. Wall., Moore). 



Variety B. Male. — Hind wings rather less triangular, trans- 

 verse band completely enclosing the discoidal spot, under surface 

 clear yellow, with minute discoidal spots, as in the extreme form 

 of T. pyrene $ . Female. — Pale yellow, with a broader dusky 

 border, the spot on the upper wings smaller and more divided 

 by the nervures, either the same yellow as the disc or more or less 

 tinged with orange ; beneath, ochreish or chrome-yellow, marked 

 as in the female of T. pyrene.
