STENIA PUNOTALIS. 73 



back, but curving forwards at the sides, and being 

 cut in two by a pale line, and each half is bordered 

 with darker brown again along this line, and also for 

 a short way along the front and back edges; the 

 spiracles are prominent, but not easy to see, and are 

 ringed with brown ; the usual dots are very tiny and 

 jet-black, placed on large shining warts ; on each of 

 the third and fourth segments there is a pair of large 

 roughly triangular warts near the front edge, and 

 four rounder ones on each side, and all these are 

 noticeably darker than the warts on the other seg- 

 ments, and apparently form a distinguishing feature ; 

 on the other segments the trapezoidals are placed on 

 large warts of an oblong shape, the front pair being 

 squarer than those behind, but with each pair the 

 greater length runs transversely ; these warts, with 

 the lateral ones, which are rounder, are all pale 

 blackish ; there is no distinct anal plate ; all the dots 

 bear fine longish bristles. 



Mr. Fletcher describes his larvae, fed on fresh 

 leaves, as being watery yellowish-green in colour, 

 with sage-green warts, this difference of course being 

 caused by the different colour of the food seen through 

 the transparent skin. 



The larva makes a toughish cocoon, lined with a 

 fabric of white silk, and coated externally with leafy 

 rubbish, about 15 or 16 mm. long, and about 6 mm. 

 wide. 



The pupa is about 11 mm. long, slender, 2 mm. 

 across the thorax ; the eye-cases are rather prominent ; 

 the tongue-, antenna-, and leg-cases, soldered together, 

 are attached to the body as far as the end of the 

 wing-cases, thence free, and reaching quite to the 

 end of the abdomen, and overreached by the spike 

 only ; the shoulders swell gradually from the head, 

 the abdomen tapers very gently, the general figure is 

 cylindrical; the anal spike is slightly curved, and is 

 furnished with six curl-topped spines ; the pupa-skin 

 is smooth, not very shiny, under a lens appearing
