94 CIDARIA POPULATA. 



the paler type. In these the head is of the same 

 colour, with two median pale lines and a reddish- 

 brown mark on the side of each lobe. On the dorsal 

 surface is a series of large, pale, almost diamond- 

 shaped whitish marks, each of these marks being 

 more or less mottled with brown spots and streaks ; 

 those on the posterior segments are the largest and 

 most conspicuous; those on the others, indeed, vary 

 very much both in size and distinctness, in some being 

 confused and not so noticeable. The pale whitish sub- 

 dorsal lines are distinct only on the second, third, and 

 fourth segments, being a continuation of the two pale 

 lines on the head ; the space between these pale lines 

 is filled up by a short black stripe, and on the third 

 segment (the swollen one) is a transverse black collar. 

 Along the spiracular region, on the lateral ridge, are 

 a few dull reddish-brown marks. The ventral surface 

 and claspers are of the same shade as the ground of 

 the dorsal surface, but there is a distinct, narrow, dark 

 brown central line, rather broadly bordered with pale 

 greyish-white. The legs are brown. 



The cocoon is very slight, and is formed by draw- 

 ing together with silken threads a few old leaves. 



The pupa is about five-eighths of an inch in length ; 

 the eye-, leg-, and wing-cases are prominent ; the anal 

 tip pointed. The colour is pinkish-brown, the wing- 

 cases streaked with dark brown ; the dorsal line is 

 broad, dark brown ; behind the head it divides into 

 a V-like mark ; there is also a dark brown ventral 

 stripe from the base of the wing-cases to the anal 

 tip. 



The first imago emerged on the 21st of June, 1875.
