6 ?. Palpus simple exteruall}', no indication of a cavity in the scaling at the 

 end of the tirst segment : on the innerside the scaling at the end of the tirst 

 segment rjnite irregular, not dense, and second segment without brnsh of hair- 

 scales at u])per angle. Antenna slender, not incrassate distally ; hook rather 

 long and gradual ; antenna of ? often with seriated ciline. Eye-lashes vestigiaf 

 or distinct. Spines of abdominal tergites numerous, small and weak ones mi-\ed 

 with strong ones, or, on the last segments, only one row of long and strong 

 conical spines (ckiroii, tersa, etc.). Spurs of hindtibia always unequal, the outer 

 one short ; spurs of midtibia unequal or equal, the outer one shorter or longer than, 

 or as long as, the inner one, the relative length varying sometimes in the same 

 species. Midtarsal comb generally distinct, that of hiudtarsus less obvious, but the 

 spines found to be somewhat prolonged when the scales are removed. Pnlvillus 

 always large ; paronychium with two pairs of long lobes. 



<J. Tenth torgite simple, truncate-sinuate at end, divided into two jirocesses in 

 chiron ; sternite bnat-shaped, transversely ribbed above at end. Clas]ier broadly 

 sole-shaped ; friction-scales large, few in number as a rule, but sometimes numerous 

 and rather small ; harpe ending in a generally small process. Penis-sheath with 

 dorso-apieal edge incrassate, developed to a dentate ridge whicii is pi'odueed into one 

 or two jiroeesses in most species, one right, the other left.
