Underside of forewiugs with basal lialf smoky grey, apical region and costa 

 tliroughont deep fulvous, towards apex striated with black ; the costa with a pale spot 

 at two-thirds and at apex ; cell-spot large, velvety black ; fringe as above ; hind- 

 wings with basal two-thirds grey speckled with darker ; outer third fulvous speckled 

 with grey, with traces of two curved dark lines ; cell-spot black. Face and palpi 

 dull olive-green ; thorax deep green and black ; abdomen cinereous olive, with 

 whitish scales intermixed ; forelegs and base of costa of forewings reddish ; anal 

 tufts largely developed, blackish, fidvous beneath. 



Expanse of wings : 44 mm. 



One (J from Chaco, Bolivia (Garlepp). 



In certain lights the black tints of the forewings assume a purplish tint. 



Euperizoma gen. nov. 



Distinguished from Perizoma Hub. by the antennae of the S being pectinated. 



The areole of fore wing is double, but vein 11 rises far back and does not diverge 

 so much as usual from the subcostal nervure, the areole being therefore long and 

 narrow, vein lO only shortly anastomosing with 11 ; the cell is more than half as 

 long as wing ; in the hindwings the discocellular is angled and the radial from below 

 the centre. Scaling rather thin. 



Type : Euperizoma mibicincta sp. nov. 



143. Euperizoma nubicincta sp. nov. 



Forewings : pale grey, with darker grey lines and with a slight rufous or 

 ochreous tinge ; basal patch obscurely darker ; central fascia formed of three diffuse 

 grey lines, all jjarallel and slightly bent in cell ; marginal area dark grey, of about 

 the same width as the central fascia, containing an indistinct waved subraarginal 

 line ; fringe grey with paler base ; marginal line formed of blackish dots in pairs on 

 each side of the ends of the veins ; the spaces on each side of central fascia form two 

 pale bands of uniform width ; cell-sjjot hardly visible. 



Hindwings : similar ; the central fascia not so well marked. 



Underside darker. Head, thorax, and abdomen all grey. 



Expanse of wings : 26 mm. 



One <? from Costa Rica. 



144. Hammaptera (?) caliginosa sp. nov. 



Forewings : blackish grey, faintly green-tinged ; basal patch separated from 

 central fascia by an oblique ochreous whitish band, broader on inner margin, with a 

 dark line down the middle, which also is broader on inner margin ; central fascia 

 broad, blackish, the wavy lines across it obscure ; its outer edge from two-thirds of 

 costa to three-fourths of inner margin, with a rounded prominence at vein 6 and two 

 more prominently projecting teeth between 2 and 4 ; followed by a pale ochreous 

 band with a fine ochreous central line ; marginal area dark grey, containing two 

 darker grey crenulated lines immediately following the i)ale band ; the submarginal 

 line pale, lunulate, interrupted beyond cell by a cloudy blackish patch reaching 

 hindmargin ; the lunule above vein 6 is filled with hoary grey scales, that between 

 veins 3 and 4 is prominently whiter ; fringe blackish grey ; marginal line obscure. 



Hindwings : pale sordid grey, jialer towards costa ; marginal area darker 

 beyond a paler lunulate submarginal line ; inner margin darker grey.
