green, which 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 he a conspicuous 

 one. Its very appropriate name is Cyclosia sanyuifcra, 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 circular spot.-; of yellow 

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

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

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

 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 Cyclosiais formed from a Greek word signi- 

 fying "a circle," and is given to the insect on account of the 

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

 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 cocoon.- of an allied 

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

 red, and from their angular shape have evidently been attached 

 to a branch. 



THESE 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 with white and 

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

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

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

 i- traversed by narrow grey streaks, showing the course of the 

 nervures. The male has the yellow pari of the wing much
