brown in colour. On 14th June, eight days after being laid, they 

 appeared to be shrivelling as though infertile. They, however, hatched 

 on 20th June. Egg period 14 days. 

 Egg and Young Larva of Hepialus Argenteomaculatus, Harris. 



Laid on 15th July, 1896. Length, .75 mm.; width, .58 mm. 



Rather even ovai. Smooth, under a 2^-inch objective seen to be 

 very slightly roughened. 



White when laid, soon turning black. 



Hatched about 7th August. Egg period about 23 days. 



Length, 1.75 mm. Head rather large, it and the plate on first 

 thoracic segment dark brown. Body slender, creamy white, with simple 

 set.ie as long as or longer than the diameter of the body. 



Papilio Brevicauda, Saunders. 



At the annual meeting in 1898, Mr. Winn read a paper on this 

 species, and Dr. Fyles, in commenting on it, as reported on p. 38 of the 

 29th Annual Report, stated that he had found the larvae hard to please. 

 He did not mention whether he had tried parsley. 



I never had so large a percentage of success with any other species. 

 I received that year, from Mr. D. Brainerd, two eggs out of five which 

 Mr. Winn sent him, which duly hatched, and I carried both larvae 

 through to imago without the least difficulty. I took them with me to 

 the meeting of the A. A. A. S. in Boston, and afterwards to Front's Neck, 

 Me. At Prout's Neck 1 found an umbelliferous plant which they 

 preferred to parsley, though when I returned home I fed them on parsley 

 again. Both imagos are now in my collection. 



Thecla Titus, Fabr. 



A fine female was taken in 1896, probably in August, and confined 

 with wild cherry. Five eggs were laid, three on the leaves near the edge 

 and two on the twig, one on each side of the base of a leaf petiole. 



The egg is round. Sea Urchin shape ; i mm. in diameter. The 

 projections are coarser, and much closer together than shown in Scudder's 

 F)g. II, Plate 65. One was pale yellow, the others considerably tinged 

 with orange. 



In the spring all the eggs were found to be more or less chipped at 

 the micropyle ; one had the whole micropyle bitten out, and the larva 

 could be seen inside the shell, but it was apparently dead, as there was 

 no movement, and none succeeded in getting out. 



I have had the same trouble with the eggs of Lyaena Scudderii*,
