8 HAUSTELLATA. — LEPIDOPTERA. 



Found, ill August and September, by the skirts of woods, and 

 in lanes ; not uncommon at Birch-wood ; near Hertford, and in a 

 lane near Stoke Newington. " Near York, males abundant, females 

 scarce." — W. C. Hcmitson, Esq. 



Genus XXXII. — Zeuzera, Latreille. 



Antennce not so long on the thorax, setaceous, of the males pectinated at the 

 base, with the apex simple; of the females entirely simple, with the base 

 tomentose : palpi obsolete : ivings entire, elongate, lanceolate, unequal. Head 

 small, tomentose: thorax stout, thickly clothed with hair: abdomen not very 

 robust, much elongated, attenuated, clothed with short hair : legs rather long, 

 shanks unarmed. Larva residing in the trunks of trees, lignivorous ; fupa 

 enclosed in a case of wood, cemented by a glutinous substance. 



Zeuzera may be known from Cossus by the structure of its an- 

 tennce, which in both sexes have the apical half simple, the male 

 having the base alone pectinated, and the female tomentose : it also 

 differs in the form and texture of its wings, and slenderness of its 

 tomentose body : by the former character it differs from Hepialus.

Anterior wings somewhat naked and hyaline : snowy white, with the costa and 

 nerv-ures yellowish ; thickly sprinkled throughout with numerous bluish-black 

 spots : posterior faintly spotted towards the base, with the inner angle imma- 

 culate, and the margin itself with a row of a deeper hue : thorax snowy, with 

 about twelve dark bluish-black spots : abdomen clothed with short dark-coloured 

 down, with a bluish metallic hue. Female considerably larger, with the ner- 

 vures more distinctly yellowish, and the spots of a brighter blue. 



Caterpillar ochraceous-yellow, with black dots, the head and tail black : it feeds 

 on the woodof the pear and apple, walnut, elm, lime, horse-chestnut {jEscuIus 

 Hippocasianum), ash, beech, birch, oak, &c.: it changes to a pale-brown pupa 

 within a case formed of the dust of the wood cemented together : it appears in 

 the imago state in the beginning of July. 



This is decidedly somewhat rare, but if industriously sought for 

 in its usual haunts, it may be obtained : it appears to inhabit a 

 considerable portion of Britain, and has been often taken in and 

 near London. " Near Jpswich."—Rev. W. Kirhi/. " Allesley,
