208 LLOYD'S NATURAL HISTORY. 



each side of the fifth segment, and another erect tuft on the 

 last. On the back are four pairs of yellow tufts, shorter than 

 the others. It feeds on most trees and shrubs growing in 

 woods and gardens, even on the poisonous Cherry Laurel (or 

 laurel, as it is generally called in England), which very few 

 insects will touch. The cocoon is egg-shaped and yellowish- 

 grey, and the pupa is yellow with dark brown wing-cases and 

 brownish hairs. 



When the female emerges she crawls about on the cocoon, 

 but never travels farther, laying her eggs upon it. Newman 

 says: "It is a very curious thing, and I believe hitherto un- 

 observed, and therefore unpublished, that these eggs do not 

 hatch all together like those of Moths in general, but come 

 out a few at a time, over a period of ten weeks, so that the 

 caterpillar, chrysalis, and Moths are all found together through- 

 out the summer and autumn." 



FAMILY XXIII. HETEROGYNID^E. 



Eggs. Deposited in the pupa-case. 



Larva. Short, slightly pubescent, onisciform. 



Pupa. Enclosed in a loose cocoon. 



Imago. Of small size, the male diurnal, with long sub-tri- 

 angular fore-wings, rounded off at the edges ; the hind-wings 

 are oval, with the hind-margin rounded. The antenrue are 

 pectinated ; the proboscis is short, and the body is hairy. 

 Ocelli absent ; frenulum present. Female smooth, vermiform. 

 There is but one genus, which resembles the Adscitina in 

 shape, and the Psychidtz in appearance and habits.
