NOVITATES ZOOLOOICAB XXIII. 1916. 173 



the cross-vein, the smaller between M and SM 2 ; a fine curved white, proximally 

 purple-edged postrnedian line 2 - 5 mm. from termen ; fringe mixed with purplish, 

 especially at apex. 



Underside whitish green, with dark cell-marks, hindwing also with indications 

 of the purplish spot distally to the cell. 



E. Bolivia : Buenavista, 750 m., August 1906 to April 1907 (Steinbach). Type 

 in coll. Tring. Mus. 



Very distinct from all known species ; best referred for the present to Eueana. 



Chloractis Warr. 



To this genns may be provisionally added " Melochlora" obnubilata Warr., 

 Proc. U.S. Nat. Mus. xxx. 419, which was unknown to me when I published my 

 revision (see Gen. Ins. fasc. 129, p. 123, Phrudocentra, Sect. IV.). In spite of its 

 superficial resemblance to P. hydatodes, on which Warren comments, I find it has 

 lost the frenulum. It differs from Chloractis pulcherrima in having the second 

 joint of the palpus rougher-scaled beneath and in wanting the terminal process of 

 the S hindtibia, besides a few points which are still more obviously not generic, 

 such as the rather longer antennal pectinations and the slightly less extreme position 

 of R 2 ; SC 1 of the forewing, so far as I have yet observed, is free aud M 1 of the 

 hindwing is not stalked, but these slight modifications I find sometimes occur even, 

 in the type species {pulcherrima). 



51. Chloractis tanaoptera sp. no v. 



S , 30 mm. Closely related to obnubilata Warr. and agreeing well in structure,, 

 though the antenna bears appreciably longer pectinations and has a somewhat 

 longer non-pectinate apical part. Conspicuously different in shape. 



Forewing with termen straighter and more oblique ; pale translucent green, 

 with minute but conspicuous black cell-dot, a narrow, cloudy, smoke-coloured band 

 just proximal to this, strongest at hindmargin and fading out towards costa, a thick,, 

 straightish postmediau line 4 mm. from termen, distal area almost entirely smoky,, 

 with a reddish or purplish hue, only at the costa, apex, and very narrowly along a. 



part of the distal margin remaining green. Hindwing with abdominal margin 



considerably longer than in the other species, recalling the shape of a Hemithea or 

 Thalassodes ; coloured and marked nearly as forewing, but with the postmedian 

 line forming a moderate sinus outward between R 3 and M 2 . 



Forewing beneath with the base vaguely suffused ; both wings with antemedian 

 band present, distal shade darker smoke-colour than above but rather more restricted, 

 particularly on the hindwing, where it leaves free a green distal margin commencing 

 as a point close to apex and gradually though not quite regularly widening until it 

 restricts the smoky shade almost to vanishing-point at abdominal margin. 



French Guiana : St.-Jean-de-Maroni, January. Type in coll. L. B. Prout. 



Subfamily STERRHINAE 

 52. Atyria dichroides sp. nov. 



Very similar to Cyllopoda claudicula Dalm. {Anal. Ent. 102), differing as 

 follows : palpus short, antennal pectinations very short (in claudicula less so), 

 areole single (in claudicula usually double), hindwing with the black longitudinal 

 streak narrowed, concentrating on M 1 (in claudicula on M'-M 2 ), hindwing beneath
