382 MR. H. W. BATES — CATALO&UE OE EETCINID^. 



Zelot^a PHASMA. 



cJ. 1" 4'". Fore-wing costa arched j apex subacute; outer margin 

 moderately rounded. Wings above pallid greyish white ; fore wing 

 with the nervures, a broadish costal border, a belt crossing the wing 

 beyond the cell from the costa to near the hind angle, a fine submar- 

 ginal line, and the outer edging pallid brown. Hind wing with the 

 nervures and a submarginal line parallel to the outer border pallid 

 brown. 



Beneath darker in colour, and nervures more distinctly bordered with 

 brown. 



Body and legs ashy white. Antennae pallid brown, spotted above with 

 ashy ; club pale ashy. 



Hab. Ega. 



Zelot^a dubia. 



cJ. 1" 4'". Very similar to Z. phasma. Wings greyish white, with 



the pallid-brown markings of fore wings much fainter. Hind wings 



without the submarginal brown line. 

 Beneath darker than above, with the fore-wing costal border and a 



broad apical and outer border light brown. Hind wing with a 



narrowish light-brown border. 

 Hab. Para. 

 This species might range as a geographical form of Z. pTiasma. 



Zelot^a achroa. 



J. 1" 6'". Fore-wing costa very slightly arched, apex subacute, outer 

 border nearly straight. Fore wing above light brown, with the outer 

 border and two or three rounded spots on the disk pallid whitish ; the 

 pale outer border has a subinterrupted brown line down its centre and 

 parallel to the margin ; the discal spots are between the branches of 

 the median nervure, the submedian, and lower radial. Hind wing 

 pallid ashy white, with the nervures irregularly bordered with brown. 



Beneath, the same, but darker, and the hind wing has a brown outer , 

 border. Antennae brown, scarcely spotted. 



Hab. Forests of the Tapajos. 



Grenus Dtsmathia, nov. gen. 



Closely allied to Zelotcea ; but the upper radial emitted at the end 

 of the cell. Antennae moderately short, pale brown, ringed 

 with paler brown, distinctly and rather strongly clubbed. 

 Palpi porrect, not visible from above. Pore legs in male 

 thinly clothed with scales ; tarsi more elongated than in Zelotcea, 

 pointed. Wings varied with dark streaks and submarginal 

 rows of spots. In one species (Z>. costalis) the fore-wing costa 

 is very strongly bowed, and the hind wing prominent at the 

 anal angle.
