the Geometrina. There is one inner vein only to fore and hind 

 wings, and these are not fnrcate. 



Species. — penumbrata Hulst, n. sp. 



S. penumbrata n. sp. — Expands 14-16 mm. Palpi jet black, front dark 

 fuscous ; head tuft and thorax smooth, even mouse-gray. Abdomen dark fuscous 

 gray, slightly interlined with lighter color ; all wings blue-gray or light mouse 

 color with a violet tinge in certain lights with three or four indistinct dark spots 

 along costa ; in old specimens there is an indication of cross-lines in the more 

 mottled surface, this being more shown extradiscally on hind wings ; discal spots 

 fine, black, not very distinct ; marginal line dark gray, indistinct, as though the 

 wing edge were black, and this covered over with gray scales and showing 

 through ; beneath even light mouse-gray, discal spots and marginal lines faintly 

 showing.

18. LOPHOSIS n. gen. 

 Type Inbecnlata Hulst. 



Palpi very short, slender; front short scaled ; antennae of % sub- 

 dentate with fascicles of hairs; fore wings probably with 12 veins; 

 hind wings 8 veins, the inner margin in % with an edging of long 

 coarse hairs near base; hind tibiie of S without spurs and with 

 strong hair pencil. 



The unique specimen of the single species is in poor condition, and 

 I am unable to examine the venation fully. The tufting on the 

 inner margin of hind wings of the % warrants generic separation. 

 Species. — L. labeculata Hulst.

Type fiirciferata Pack. 



Palpi short, slender, front smooth ; antennae simple, evenly ciliate ; 

 hind tibise of % very weak, the whole leg partially aborted ; fore 

 wings 8 veined ; 8, 9 and 10 wanting, 5 near 6 ; or the interpreta- 

 tion may be : 5 wanting, 6 and 7 separate, 7 separate from 8, 9 and 

 10 wanting; on the inner margin of the wing within vein 2 is a 

 swelling out of the wing modified above into a sort of a fovea cov- 

 ered with enlarged scales ; it is probably an incomplete fold ; hind 

 wings very much distorted in venation ; 6, 7 and 8 present as usual, 

 6 and 7 stemmed, but the posterior part of the wing formed into a 

 broad fold extending the whole length of the inner margin, the 

 venation being greatly distorted ; the fold is edged within with long
