. Butterflies. Vol. Lepidoptera. CYRESTIS. 351 tail, very much compressed, with a dorsal ridge from head to tail, high and obtusely pointed in the middle, the palpi-cases united and produced into a long somewhat recurved snout; colour brown with fine dark striae/*' {Davidson Sf Aitken.) Race andamanica, & de N".â <$ $ . Very closely resembles the typical form; the dark markings, however, are as a rule heavier and more pronounced, but in this some specimens from the Anaimalai hills approximate very closely to the lighter coloured Andaman individuals. One constant point of difference, however, seems to be the large amount of rich ochraceous colour on the upperside of the hind wing posteriorly. The costal margin and the postdiscal series of rings on the fore wing are also strongly tinged with ochraceous. Exp. As in the typical form. Hob. The Andamans. Apparently common at Port Blair. 365.

Fore wing : costal margin for about half its length dusky black, bordered on the extreme mar- gin at the base with ochraceous; cell crossed by four slender black lines, the innermost but one continued to the dorsal margin : beyond the cell the disc crossed by three irregular slender black lines from costa to dorsum, the outermost widening posteriorly, where it is succeeded by a large ochraceous spot, bearing in the middle two minute black dots, at the tornal angle; apex and termen broadly dusky black, traversed by four or five very slender sinuous greyish-white transverse lines ; the inner two form subapically an irregular triangle. Hind wing crossed by four slender, sinuous, parallel black lines, a broader black liue
