8 DIPHTHERA ORION. 



hairs of its body were interwoven ; a little more than 

 five-eighths of an inch long by three-eighths broad, 

 compact and somewhat ovate in form, and of light- 

 brown colour; spun within the angle of its cage 

 (August 10th) the web very opaque. 



On the evening of June 4th, 1876, the moth, a S , 

 appeared. 



On examining the cocoon, I found it had a small bit 

 or two of oak leaf, woven in, and was very strong in 

 texture. The pupa skin was little more than half an 

 inch in length, stout in proportion, tapering from the 

 lower margin of the wing-covers to the end of the 

 abdomen, where it was rounded off and furnished with 

 six equidistant, short, curved outwards, spikes on the 

 anterior surface ; on the dorsal surface from the 

 spiracles on each side was an anterior transverse line of 

 coarse and deep punctures, forming a roughened ridge, 

 nearly close to the division of the foregoing segment ; 

 on the fifth, sixth, and seventh beyond the thorax was 

 near the end of each, a plain projecting edge. Its 

 colour was very dark purplish-brown, nearly black, 

 and shining, except just at the segmental divisions, 

 the back being the most lustrous. (W. B., Note Book 

 III, 17.) 



ACRONYCTA LEPORINA. 



Plate LVI, fig. 3. 



One young larva on birch was received from Mr. 

 W. H. Cole, September 3rd, 1874; it was then five- 

 eighths of an inch long, and on the 9th was little 

 more than three-quarters of an inch in length, and 

 was then preparing to moult. 



It was of a light greenish yellow, and its skin 

 glossy ; the head pale olive green, marked with black 

 on the top of each lobe and on the front margins and 

 lower parts of them ; two black dorsal marks on the 

 second segment, two dorsal black dots on the third,
