114 LLOYDS NATURAL HISTORY. 



The female is larger than the male, with slightly serrated 

 antennae. 



The larva is light or dark brown, with brownish-grey stripes. 

 On the third and fourth segments are two deep orange-coloured 

 humps, varied with black. On the rest of the back is a 

 longitudinal row of connected yellowish spots, edged with 

 darker. On the head and on both sides, near the legs, are 

 prominent, yellowish-brown tufts of hair, placed on white 

 tubercles. 



The pupa is brown, and is enclosed in a dense, silky white 

 or light grey oval cocoon. 



The moth appears in July and August. 



Unless my memory fails me, I have somewhere seen it 

 suggested that the famous Coan silk may have been obtained 

 from this insect. 



GENUS PHILHYDORIA. 



Odonestis (nee Germar), Stephens, 111. Brit. Ent. Haust. ii., 



p. 51 (1828). ^ 

 (^^/tv^t'^-Z/j-, Walker, List Lepid. Heter. Brit. Mus.vi.,p. 1409 (1855). 

 Fhiludoria^ Kirby, Cat. Lepid. Heter. i., p. 820 (1892). 



The genus Odonestis of Germar was formed to include two 

 species^ Boinhyx primi and B. potatoria of Linnaeus. As, 

 however, the latter was placed in it with doubt, it follows 

 necessarily that B. primi (a reddish-brown Continental species, 

 with dentated wdngs, and a white spot in the middle of each 

 fore-wing) must be regarded as the type of Odonestis. 



In Philhydoria the antennae are long, and strongly pecti- 

 nated in the males ; and the palpi are long and stout, forming 

 a beak. The hind margin of the hind-wings is slightly waved, 

 and the abdomen is tufted in the male. The sexes are very 

 dissimilar.
