green, wliich presently gives place to yellow, and then to black 

 on the edge ; the nervures retaining their green colour and giving 

 a series of green lines to the very edge of the wing. 



On Plate XV. Fig. 2 is pictured an insect which, even under 

 the exigencies of printer's ink, shows itself to be a conspicuous 

 one. Its very appropriate name is Cyclosia sanguifcra, and it 

 is a native of Northern India. 



The ground colour of the wings is glossy black, and upon the 

 upper pair near the base are a number of circulnv spots of yellow 

 and blue. On the rest of the wing is drawn a complicated 

 'pattern of stripes, looking just as if they had been painted with 

 blood. The lower wings are black from the base to two-tliirds 

 of their length, and are adorned with circular spots of vivid 

 blue. A broad band of the same blue occupies the edge of the 

 wing, and on it is a row of white spots. 



The generic name Cyclosia is formed from a Greek word signi- 

 fying " a circle," and is giv^en to the insect on account of the 

 many circular spots upon its wings. The specific name sangiti- 

 fera is a Latin word signifying " blood-bearing," and refers to 

 the red stripes on the upper wing. When the insect is at rest 

 its outline assumes a beautiful shape. The under wings are 

 completely covered by the upper, the spots and streaks forming 

 a most singular and striking pattern. 



In the British Museum are two empty cocoons of an allied 

 species, Cyclosia suhcyanctis. They are of slight material, rust- 

 red, and from tlieir angular shape have evidently been attaclied 

 to a branch. 



Theee are many species of the genus Hypsa, and in most of 

 them the chief colours are yellow and grey. 



The present species is remarkable for the difference in appear- 

 ance between the sexes. The figure represents the female, which 

 is coloured as follows. Both pairs of wings are from the base 

 to two-thirds of their length pale yellow, edged witli white and 

 sprinkled with black spots. On the edge of tlie wings is a band 

 of pale brown, very broad at the tips of the upper pair, and 

 narrowing gradually to the angle of the lower pair. This band 

 is traversed by narrow grey streaks, showing the course of the 

 nervures. Tlie male has the yellow part of the wing much
