tibicB with a spiniform lobe on the inner margin : wings entire, sub- 

 diaphanous ; anterior lanceolate-ovate, with a single prominence on 

 the inner margin. Larva naked, without dorsal protuberances, the 

 back slightly rugose, the sides obliquely streaked : /)?/^a folliculated, 

 the folliculus placed on the surface of the ground."— <S/eyj//. /. <?. II. 32. 

 * Zeuzkra, Latr. Steph. 



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

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

 the base tonientosc ; palpi obsolete ; wings entire, elongate, lanceolate, 

 unequal, //rrtrf small, tonientose : 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 ; pupa inclosed in a case of wood, 

 cemented by a glutinous substance." — i7c;j^. Illimt. Brit. Ent. II. p. 8. 

 Stephens adds, that Zcuzcra is distinguished from Cossits by its antennte 



in both sexes having the apical half simple, by the form and texture of the 



wings, and by the slcnderness of its tomentose body.
