Head, thorax, and abdomen concolorous. 



(?. Witii/s : bone-colonv, spocklwl and striatod witli blackish; lines hardly 

 visible ; nnderside ochreons, yellow towards hindmargins, with distinct short black

Expanse of wings : 30 ram. 



1 J. 1 ? from Palino cue, Paragnay, Miirch (Montforts). 



The difference in coloration, bnth above and below, in the two sexes is 

 remarkable ; the S is considerably worn, which may partly acconnt for the 

 obscurity of the markings. 



In nenration the S agrees with Coehira omnna Drncp, and not with the tyjie 

 species fraiisi-rrstifa Warr., veins 2, 3, 4 of forewing rising all separate but near 

 together, and veins 3, 4 of hindwiug being stalked ; in the ? the discocellnlar of 

 hindwing is vertical, not oblique, and the cell longer. 



3. Erosia veninotata spec. nov. 



Foretving : brown, with black speckling and striation ; the lines black, the 

 central area between them slightly darker than the basal and marginal ; first 

 line from one-third of costa to one-third of inner margin, strongly outcurved 

 and projecting on vein 4 ; outer line from before two-thirds of costa to three-fourths 

 of inner margin, curved inwards at first, then fiom subcostal to vein 4 straight and 

 vertical, obliquely curved inwards to vein 'Z, then again oblique outwards ; this line 

 is edged outwardly by a pale ochreons line, and veins 1, 2, 3, are pale ochreons 

 across the darker fascia ; a curve of dark scales before the excision ; an undefined 

 submarginal shade of blackish striae and traces of some dark shading in the 

 basal space ; fringe worn. 



Ilindiring : similar, but the inner line is edged inwardly with ochreons, as 

 well as the second outwardly ; the angle of the onter line at vein 4 acute ; costal 

 half of wing above median vein and vein 4 washed with pale chestnnt; the lower 

 lialf of fascia dark brown, followed by a jialer, oclireons, band ; a brown line 

 from upper to lower tooth ; a broad olive-brown line fiom base above median 

 vein to angle of onter line. 



Underside ochraceons, somewhat darker and striated with black towards 

 hindmargins. 



Face and paljii black-browu ; vertex and thcirax i)ale fawn ; the abdomen 

 darker ; nnderside of abdomen and pectus whitish ; legs ocbraceous and grey.

1 ? froiu Tuis, Costa Hica. 



The markings are differently disposed from those of any of the forms that 

 can be referred to incendiata Guen. 



Gymnoplocia gen. nov. 



Closely resembling T>iradcs, but differing in the following points ; the furrow 

 within the fold of inner luargin of hindwing is qnite bare, showing no trace of 

 a pencil of hair, but instead a short tuft of s])reading hairs rises from the base 

 of the inner margin ; at the base of cell of hindwing is a large hyaline oval 

 space ; costa of hindwing slightly sinnous, without hairs. In the forewing vein 11 

 is free but upcurved towards 12, witliout, however, anastomosing. 



Type : Gymnoplocia paicidens Dogn. (Epiplema).
