Revision of Scopelosoma Curtis. 



BY JOHN B. SMITH. 

 Genus SCOPELOSOMA Curtis. 

 1S38 Curtis, British Insects xiv, 635. 

 Eyes naked, strongly lashed; the lengthy strong hair almost 

 meeting over the eye. Head strongly retracted, the front clothed 

 with short, loose, somewhat divergent vestiture; palpi very short, 

 scarcely reaching the front. The antennae are simple, or with a 

 single lateral bristle in the 9 ; simple, with lateral tufts of fine short 

 hair in the %, . Thorax quadrate, somewhat depressed; vestiture 

 hairy, in some species with elongate scales intermixed; rather long 

 and decumbent, smooth. The collar is slightly prominent in front, 

 and there is an elevated anterior crest, very distinct in good speci- 

 mens. The abdomen is depressed, in the S more or less flattened, 

 little or not exceeding anal angle of secondaries. The legs are un- 

 armed, and the underside is rather thickly clothed with woolly hair.
