to a band round each segment with a clear interspace between. 

 This is noticeable in the illustration of trifenestrata larva plate II. The 

 larvae prefer to feed head downwards. Length i l / 2 inches. 



4th Stage : There is practically no difference in this age except that 

 the spots on tubercles are brighter apricot red and more raised on a 

 Alight mound than previously; the head still black is quite pubescent with 

 greyish hairs. Color slightly more greenish and with a pronounced 

 lateral ruga or longitudinal fold of skin along the sides, length 2^/2 

 inches and the larva rather slender, the spines on tubercles on thorax 

 quite urticating enough to raise a slight blister. 



5th Stage : There is no change of note except that the lateral ruga is 

 more pronounced and the anal tubercle is larger proportionately than 

 before. The larva has a very soft and weak feel, but sticks tenaciously 

 to anything it touches. Length about 3 to 3'/^ inches long, according 

 to sex apparently. They are now feeding mostly solitary. They were 

 all fed on oak. 



They commenced to spin up August and some emerged in September 

 and October. I had some pairings and these eggs commenced to hatch 

 in October; some I sent to the cold store here, temperature 38-40 deg. 

 F. These I have just put in a warm room, but have not hatched 

 March 22nd. As it was a new species I did not wish to lose it and I 

 distributed eggs over the continent within a few days' journey. Some 

 sent to the Zoological Gardens, London, were reared and the 4 cocoons 

 sent me back are darker russet brown than the original ones, while 

 some reared on Privet and Rhododendron are pale greenish yellow. 

 At the time of writing, March 22nd, I have one feeding on Rhododen- 

 dron. This species will stand cold and frost occasionally. 



Pupa closely covered with large punctures which are darker colored 

 and larger and more numerous than trifenestmta. Pupal skin is a 

 dull yellow whilst in trifenestrata, the color is darker and with finer 

 punctures. 



The moths of the third generation (the winter brood) have 

 just commenced to emerge and are of a darker color than 

 the other broods. T have one male of a bright reddish pink 

 with pink costa to forewings.
