know both sexes of the species he named, or that his specimen was a female while Drury's was 

 a male of one species, hence the confusion that has arisen. 



Mr. E. H. Aitken has furnished me with the following short note on the transformations 

 of this species: " The larvae of both Ergolis ariadm and Byblia ilithyia were found on 

 Tragla cannalina, and were so similar that the only distinctive mark was the dorsal light-green 

 or greenish-yellow broad band, which in the latter was continued to the anal extremity, while in 

 the former it reached to the middle only. The colour on the sides was sometimes green, but 

 generally almost black. Length about an inch, E. anacine being a little smaller ; shape 

 cylindrical, slender for its length, with two longitudinal rows of branched spines. There 

 were twelve pairs of these spines, besides the peculiar pair on the head nearly a quarter 

 of an inch long and not branched, but terminating in a crown-like expansion. The pupa 

 is rather slender, colour sometimes green, sometimes brown. In this stage the two species 

 seem indistinguishable." 



The figure is taken from a male Madras specimen in the Indian Museum, Calcutta, and 

 shows both sides.

Hyfianis simplex, Butler, Proc. Zool. Soc. Lond., 1883, p. 146, n. 7, pi. xxlv, fig. 8 ; id., Swfnhoe, Proc. 

 Zool. Soc. Lond., 1885, p. 129, n. 33. 



Habitat : Depalpore, a lake-district 30 miles north of Mhow ; Assirghar ; Poona. 

 Expanse : i'6 inches. 



Description: " Allied to the African H. l-B.I cora. Upperside tawny with black 

 markings as in little-marked females of ZT. [ = ^.] ilithvia of Africa. Underside very like 

 H. [=B.]co,a, but the black discoidal markings of the foreiving distinctly white-edged, the 

 subapical white spots larger and clearer, the submarginal black band near external ancrle 

 reduced to a mere undulated stripe ; the first and second white bands of the hindimn,^ p„re 

 not crossed by coloured veins, edged on both sides with black dots ; submarginal white spots 

 less vvidely separated ; an undulated white marginal stripe in place of the pairs of white 

 dots." (Butler, I.e.) Mr. Butler does not indicate the sex of the specimen he describes and 

 figures : it appears to be a female however. 



B. simplex has as yet only been taken by Cilonel C. Swinhoe as far as I know, he has 

 found it at Depalpore in Central India in January ; at Alhow in June, July, and October 

 common ; at Assirghar in September ; and at Poona in November, December and January' 

 common. I have not seen a specimen of this species. From the figure it appears to be distinct' 

 thehmdwmg on the underside much paler, with a submarginal chain of large white or 

 yellowish spots inwardly defined with a fine black and then a white line, while in B. ilithvia 

 the latter is broken up into white spots in pairs. " 



The next group of the Nymphalina: contains ten genera, which are distinguished by 

 having only the first of the subcostal nervules of the forewing emitted before the end of the cell - 

 the second subcostal nervule being emitted beyond the origin of the upper disco-celluL.; 

 nervule, which marks the end of the cell. This group is further divided into two sub-c^roups 

 the first five genera having the second subcostal nervule emitted far beyond the end of the cell' 

 while in the other five it is emitted close to the end of the cell. ' 



With the exception of Melitma which is a Paltearctic genus, only extendin^r into our limits 

 in the high ranges of mountains on the North and North- West, the whole'of the -enera of 

 this group are either confined to the southern slopes of the Himalayas extendin- to ^he hills 

 east of the Brahmaputra, or else are spread through the Indo-Maiayan re-ion, one genus 

 extending to Africa and another to Australia. Most of the genera of this group comprise but 

 few species.
