( 187 ) 



Underside dark o-rey-brown ; the costal blotch pale ochreons in both sexes, witli 

 the costa itself above the blotch deep yellow ; a slight pale spot in middle of hind- 

 wings, which in the ? is visible also above. Head and shonlders pale ochreons, 

 paler in the ? ; thorax and abdomen pale grey-brown in ?, dark grey-brown in cJ ; 

 the basal segment of abdomen and the anal tnft of the c? ochreons. 



Expanse of wings : 26 mm. 



A pair from Paramba, Ecuador, Jan. to May 1897. 



Sdbfamily NEPHODIINAE. 

 164. Astyochia nigrita sp. nov. 



Forcioings : smoky black, the veins and costa deep black ; space between the 

 median and submedian veins and basal half of cell semi-transparent ; a white blotch 

 towards apex beyond cell, extending from vein 4 to 7 ; fringe black. 



Ilindwings : white, with a broad deep black border along costal and hind- 

 margins ; veins and inner margin narrowly deep black. 



Underside similar ; the semi-transparent spaces on forewings whiter. Head, 

 thorax, and abdomen deep black ; tongue bright yellow ; taft of hair on inner 

 margin of hindwiugs grey. 



Expanse of wings : 24 mm. 



Two c?c? from R. Tanampaya, Bolivia, 1894 (Garlepp). 



Hyalocampa gen. nov. 



Forewings : with costa nearly straight, curved just before apex ; apex rounded ; 

 hindmargin rouuded, not very oblique ; anal angle distinct. 



Ilindwings : with both angles and the hindmargin rounded. 



Antennae of c? bipectinated nearly to apex ; of ? simple; paljn porrect, slender, 

 short ; tongue and frenulum present ; hind-tibiae with four short spurs. 



JS^euration : forewings, cell three-fifths of wing, constricted at its extremity ; 

 discocellular short, inangnlated in middle ; first median nervule at three-fifths, 

 second at seven-eighths ; radials normal, the lower one fine ; 7, 8, stalked ; 10 

 and 11 free ; 11 connected by bar with 12, 10 anastomosing with 11; hindwings with 

 costal approximated to subcostal, and united by a bar just before middle of cell ; 

 vein 7 from before end of cell ; first median nearly at one-half, second just beyond 

 three-fourths. In the forewing in both sexes veins 3 and 7 are strongly bent down- 

 wards, approaching veins 2 and 6 on hindmargin ; in the cj the median and submedian 

 veins are strongly concave towards each other near base ; the foveal bar is thick 

 and strongly marked, lying on a very fine curved fold from submedian fold to 

 median vein ; above the curve of the submedian vein a straight chitinous bar 

 appears, covered with black scales, the wing membrane above it being finely fluted ; 

 the wing membrane perfectly transparent, without pigmented scales. 



Tj'pe : Hyalocampa specularis sp. nov. 



16.5. Hyalocampa specularis sp. uov. 



Forewings: perfectly hyaline; except along the margins and an oblique bar 

 across the end of cell to hindmargin at vein 3, where, as well as at apex, the 

 hindmarginal border is wider ; all the veins black. 



Hindwings : without the oblique bar, and with the inner margin very narrowly 

 black.
