This genus includes a number of species inhabiting the 



warmer regions of the Old World. They measure about an 



inch across the fore-wings, which are about twice as 



long as the hind-wings, and rather pointed. The wings 



are marked with large yellow or hyaline spots, and the body is 



pubescent, rather stout, and belted with red and blue ; the 



abdomen extends for the greater part of its length beyond the 



hind-wings. The larva is furnished with erect tufts of hair, 



with longer ones before and behind ; the pupa is enclosed in a 



thick cocoon.

 {Plate LXXXI. Fig. 5.) 

 Euchromia siamensis^ Butler, Journ. Tinn. Soc. Lond. Zool, 

 xii. p. 365, no. 13 (1876). 

 This Moth, which is allied to E. polymelia (Linn.), the type 

 of Euchromia^ belongs to an East Indian section of the genus 

 which is black, with extensive ochreous- or orange-yellow 

 markings on the fore-wings. E. siauiensis measures nearly two 

 inches across the fore-wings, which have an oblong orange- 

 yellow mark near the base, between the median and sub- 

 median nervures ; a larger one beyond, separated from a 

 narrow one in the cell above it, by the median nervure ; and 

 four long sub-apical ones, divided by the nervures, with the 

 two middle ones separated by a wider black space. Hind 

 wings with two spots, one near the base, and one sub-apical, 

 each divided into three by the nervures. Body black ; 

 antennas pectinated ; vertex metallic blue ; collar red ; a red 

 spot above the base of each fore-wing ; abdomen with an 

 ochreous band at the base ; segments two and three broadly 

 edc^ed with white behind on the sides, and marked behind
