new Species of Oriental Lepidoptera. 107 



Fam. Papilionida?. 



Subfam. Pierinxi. 



9. Dercas enara 7 nov. 



£ . Larger than D. brindaba, the apical black patch 

 running somewhat into the veins, instead of being nearly 

 square cut as it is in brindaba ; the inner margin of this 

 patch is marked with bright orange colour, and so is the 

 discal band, both characters wanting in the Indian form ; no 

 discal spot 011 the fore wings. 



? . Pale primrose, the apical patch more restricted, the 

 pointed apex sometimes merely irrorated with black ; the 

 discal spot prominent as in the female of Wallichii. 



Omei-shan, W. China. Many examples. 



Mr. Leech in his ' Butterflies from China, Japan, and 

 Corea,' p. 445, gives Doubleday's description of the male of 

 Wallichii with the discal spot, but he figures (pi. xxxv. fig. o) 

 the form I now call enara. Perhaps a form with the black 

 discal spot on the fore wing of the male does occur in China, 

 but I have not seen it; all those received by me have been 

 without it. 



10. Dercas brindaba, nov. 



$. Like D. Wallichii, Doubl., but without the large 

 blackish-brown spot in the interspace between the first and 

 second median nervules of the fore wings above. 



Khasia Hills. Numerous examples, all males. 



This insect has been placed under the name of D. urania, 

 Butler *, in all Indian collections; but urania is merely the 

 female of D. Wallichii. I have received D. brindaba in great 

 quantities from my Khasia Hill collectors during the past eight 

 years; it always comes with D. Wallichii and is the commoner 

 of the two. Though the discal spot in Wallichii is sometimes 

 larger, sometimes smaller, it is never evanescent, and I 

 think, therefore, I am justified in saying I have never 

 seen an intergrade between the two ; but whether it be a good 

 species or merely a form of Wallichii it is very distinctive, and 

 for the sake of convenience should have a name. I have 

 never seen a female ; it very probably closely resembles the 

 female of Wallichii, as is the case with the allied Chinese 

 form. 



Fam. Hesperidse. 

 11. Hasora haslia, nov. 

 £ . Upperside black, without markings : fore wings with- 

 out the sex-mark. Underside dark brown, tinged with lilac, 

 * P. Z. S. 1805, p. 458, pi. xxvi. fig. 5.
