NEPTICULA TURICELlA. SJ99 



Larva. — The head is black, especially its posterior lobes ; the 

 cephalic ganglia also are black, and look like a part of the head ; the 

 ventral nerve-cord, also, is fairly visible when the leaf is turned over 

 (Wood). The larva is yellow in colour (Threllall). 



Cocoon. — The cocoon is very pale yellowish in colour (some almost 

 whitish) surrounded and entirely covered by a large amount of 

 loose flossy silk of the same colour. It is almost a perfect oval in 

 outline, and although flattened, is much less so than the cocoons of 

 many other species. [Described June 7th, 1898, from cocoons sent by 

 Dr. Wood.] The cocoon is woolly, and white in colour (Wood). 

 Heinemann writes : " The cocoon is longish, much arched, and of an 

 ochreous-yellow colour." Length of cocoon 2-4 mm., width .1-4 mm. 



Food-plant. — Fatjus sylvatica. 



Time of appearance. — The species is double-brooded, the imagines 

 appearing in May and July-August, from larvre feeding in October and 

 June-July respectively. Imagines were captured at Arnhem, on May 

 13th, 1873, by De Rooy. From larvae obtained in October, in 

 Hanover, imagines were bred in May. Farren breeds the imagines 

 in May and June, from larvae obtained September- October, at 

 Cambridge. Bower captured imagines at Bexley, May 20th, 1887. 

 Threlfall bred imagines from April llth-20th, 1878, from larvae 

 captured at Grange, October 5th, 1877.
