378 NOVITATES ZOOLOGICAE XXIV. 1917. 



outward curve, angulated inward at R*, lobed outward at R'-M', then receding 

 to M', curving, falling almost verticallj' on hindmargin beyond two-thirds ; 

 terminal line black, interrupted by whitish dots at the veins ; fringe ochreoua 



whitish, with elongate blackish spots (dashes) opposite the veins. Hindiving 



with abdominal margin long, tail rather strong ; first line obsolete ; cell-mark 

 elongate ; the rest as on forewing. 



Underside whitish, shghtly opalescent, the forewing and a small terminal 

 area on hindwing towards apex with a rosy tinge ; no distinct markings ; ter- 

 minal line and fringe as above, but both intensified at tornus of forewing and 

 apical region of hindwing. 



San Esteban, N. Venezuela, June — July 1909 (S. M. Klages). A good 

 series in coll. Tring Museum. A single <? from Sapueay, Paraguay, October 

 1904 (W. Foster), was mixed by Warren with pallescens Warr. (see Nov. Zool. 

 xvi. 76). True ■pallescens (from Oconeque, Carabaya) has normal bipectinate 

 (J antenna, but is not, as was suggested, an aberration of subrufescens Warr., 

 the (J lacking the hindtibial hair-pencil which is developed in that species.

I cannot find any solid basis for generic separation of any of the above, 

 which have mostly been founded on minor sexual characters or sUght differences 

 in shape or pattern. Possibly even Trygodes Guen. {Spec. Gen. Lep. ix. 426) 

 will also have to be merged with them. The o antennae show the finest inter- 

 gradations from the heavily pectinated to almost simple, cihated. The stalking 

 of SC of the forewing, which would separate off Dysephyra, is usually (though 

 not invariably) constant for individual species, but would in any case j'ield 

 rather unnatural groupings, as it occurs not only in a sprinkling of siDecies with 

 the Dysephyra-Heterephyra facies (jiistata Walk., ruhida Warr., ella Hulst — the 

 type of Charommataea — etc.), but also in ^^ Parazeuxis" puntigera Dogn., in 

 Semaeopus incolorata Warr., oenopodiata Guen., and trygoduln Warr. (Nov. Zool. 

 xi. ."Se, as Craspedia). 



8. Semaeopus semicaeca spec. nov. 



(J, 34-36 mm. Head and body mostly concolorous with \\ings ; vertex 

 and base of antenna darkened ; palpus rather short, somewhat reddtned on 

 outer side, pale beneath. Antennal pectinations fine and rudimentarj-, sur- 

 mounted by moderate tufts of cilia. Hindleg with strong pencil of hair from 

 femoro-tibial joints and strong red and white tufts on tibia and tarsus.
