variuble iiitun.sity, from beyond tJie angle of outer line to inner ina.rgin before anal 

 angle ; a row of small dark marginal dots ; fringe ochreous : cell-spot black. 



Uindwinys : with cell-spot, antemedian and postinedian lines, and distinct 

 submarginal shade. 



Underside with the markings thicker, brown ; forewings washed with yellow, 

 e.xcept a square apical blotch and smaller blotches along hindmargin, which are 

 white ; hindwings with the basal area, the space between last two lines, and the 

 veins yellowish, the rest white. Thorax and abdomen concolorons with wings : head 

 and collar rather deeper. 



Expanse of wings : 2fl mm. 



Three <S i — one marked simply Amazons (ttipe), one from between Manaos 

 and R. Jntahi, and a third frotn La Plata. The last is rather larger and more darkly 

 marked than the two from the Amazons. One ? from R. Dagna, Colombia fW. 

 Rosenberg). 



Distinguished from A', subdiverm Warr., to which it is evidently closely allied, 

 by the smaller size and jKiler ground-colour. It is also like »S. aequiferaria Wlk. 

 from Florida, and might easily be mistaken for that species ; but the $ antennae 

 are quite distinct, and the hindmargin of forewings shows no trace of excavation. 



The single ? from Colombia has the markings more obscured by the denser 

 dusting ; the black vein-dots on veins 3 and 4 are intensified and united into a black 

 line, followed by a second blotch lying on the snbmarginal line, which is otherwise 

 not represented above, though clearly marked on the under surface ; in the hind- 

 wings the postmedian line is immediately followed by a dark shade, forming with 

 the submarginal shade a donble baud. The species is evidently widespread, and a 

 longer series will probably show fnrther variations. 



194. Xenoecista subdiversa sp. nov. 



Forewinyx: whitish, the ground-colonr almost hidden by dull greyish fuscous 

 strigae and irroration ; the three lines parallel to the hindmargin and nearly equi- 

 distant, all bent below the costa, and the median obscurely forked, the small black 

 cell-spot lying within the fork ; all three rather thick and diifuse, the exterior slightly 

 waved and marked on each side with black scales at veins 3 and 4 ; submarginal 

 line waved, indistinct, the space between it and the exterior line forming a darker 

 fascia ; fringe grey, with a fine dark basal line. 



Hindwings : with the median line thickened, preceding the black cell-spot, the 

 submarginal foscia broader and more marked. 



Underside with the markings dull red-brown : the forewings wholly suffused 

 with dull yellowish ; marginal area wholly red-brown, except a fuscous-dotted square 

 white apical blotch ; hindwings suffused with yellowish only as far as first line, the 

 rest white, with the markings red-brown. Head, thorax, and abdomen like wings. 



Expanse of wings : 30 mm. 



One <J from Bogota. 



I'J.J. Xenoecista triconjimcta sp. nov. 

 Forewings : greyish ochreous, grizzled with dark grey and brown atoms ; first 

 line at one-fourth, thick, dark brown, angled below subcostal and partially double; 

 second in middle, similarly angled, then oblique and fine ; outer line brown-black, at 

 three-fourths, nearly straight, closely followed by two similar lines, the outer one 

 somewhat dentate, all the three forming a diffuse brownish fascia ; fringe grey.
