some distance below the apex. Articulated plate triangularly 

 widened, the outer margin entire. Basal hooks long and re- 

 curved, somewhat broadened, but with pointed tips. Basal 

 appendages large, obliquely quadrate, setose, the setse toward 

 the produced outer angle longer.

Clasp-filament with the outer part broadly elliptical, the tip 

 drawn out into a horn on which the narrow appendiculate spine 

 lies; a dorsal crest of very short pile. Outer division of lobe 

 of side-piece rather shortly columnar, without arm, a large 

 broadly expanded leaf on the inner angle, accompanied by a 

 small filament ; middle filament also forming a leaf, more deli- 

 cate than, but almost as large as the inner one ; three filaments 

 on the outer aspect of the lobe toward tip. Inner division of 

 lobe of side-piece with the arms well separated, the outer 

 rather long, the inner nearly half as long as it, each bearing a 

 stout filament with expanded hooked tip. Second uncal plate 

 stout, furcate, one limb (inner) pointed, the other more 

 rounded ; a stout curved horn from about the middle of the 

 stem. Articulated plate expanded trigonate, infuscated, the 

 margin smooth. Basal hooks moderately long, stout and 

 widened, but recurved and with pointed tips. Basal append- 

 ages large, produced, being three times as long as wide, indi- 

 cating the development of tecinarsis, though by no means so 

 extreme, with many setae, those toward the tip longer. 



From British Guiana. I described this in Mochlostyrax on 

 account of the shape of the clasp-filament ; but the uncal plates 

 are not formed as in that subgenus, being quite characteristic 

 of Choeroporpa. I therefore transfer the position. The larva 

 is not at hand to confirm or disprove the reference.
