+ Stauropus fagi, Steph. 



Mr. Stephens has separated this insect from the Cerura:, and placed it 

 by itself under Germar's genus Stauropus, which " differs from the other 

 genera of this family by having several patches of elevated scales on the 

 anterior wings, which are rather densely clothed with scales, and somewhat 

 pilose." 



« Genus .38. STAUROPUS, Germar. 

 " Pa/pi short, clothed with elongate scales, straight, cylindric, biarticulate, 

 the terminal joint acute ; maxillcB obsolete. Antenna; porrect, simple 

 at the apex ; of the male, strongly bipectinated from the base nearly 

 to the tip ; of the female, simple throughout ; head very small ; eyes 

 large ; thorax not very stout, nor crested ; abdomen somewhat elon- 

 gate, rather attenuated towards the apex, which is furnished in both 

 sexes with a tuft of fine woolly hair ; wings entire, thickly clothed with 

 scales, with several elevated tufts of scales and down; anterior lanceo- 

 late-ovate ; jKsterior ovate-triangular ; legs rather short, thickly clothed 

 with down : anterior tibia: in both sexes with an elongate attenuated 

 spine or lobe; posterior with s])ines at the apex only. Larva naked, 

 the back with several acute jirotuberances, the caudal segments late- 

 rally expanded and rcflcxcd, with the hinder prologs converted into 

 twostyliform processes: pw^ja foUiculatcd." — Steph. Illust. Brit. Ent.
