Habitat : Côte de l'Or, Abusi, i $ au British Muséum. 



Diagnose originale. — « Face yellowish, clypeus brownish, vertex 

 with tufts of long white hairs, also on the pronotum; antennae as long 

 as width of fore wings, curled, tapering to tip, rich brown in color. 

 Abdomen brown, with médian lobes above, with sparse white hair 

 above and denser yellowish hair on sides; the ovipositor yellowish, 

 about one third the length of the abdomen; legs pale, tarsi yellowish, 

 basai half of hind tibia and apical part of middle tibia dark, legs with 

 mostly long hairs, but some dark ones. 



Fore wings with two faint broad oblique gray bands, one before 

 middle, one at the middle, and several large patches beyond, the 

 space between thèse marks snow-white; the cross-veins black, and 

 black haired, and a black spot at anal angle, other veins mostly 

 yellowish, with long hairs, mostly white, but some in costal area are 

 black. Venation very similar to N. nobilis Nav„ but a cross-vein Con- 

 necting the second and third branches of the radial sector toward 

 tip, thus four veinlets in the outer séries of gradates ; hind wings 

 similar to N. nobilis, but no cloud black of the sigma, the latter very 

 distinct. Veins similar to N. nobilis, but the extra apical cross-vein, 

 the lack of cloud in hind wings, several détails in color of the legs, as 

 well as différent locality lead me to consider it a distinct species. 



Expanse : 15 mm.

Je n'ai pas vu l'insecte en question. Mais M r Herbert Campion, 

 du British Muséum, a eu la grande amabilité d'examiner pour moi 

 le type et unique exemplaire connu et de m'envoyer une magnifique 

 photographie des 4 ailes. Je l'en remercie de tout cœur. 



Au point de vue de la coloration, j'apprends ainsi que « in a 

 suitable light I can certainly perceive a slight cloud behind the 

 stigma in each hind wing ». Par conséquent, cette différence émise par 

 Banks (en opposition avec N. nobilis) n'existe pratiquement pas, 

 puisque les exemplaires peu colorés sont dépourvus de ce « cloud 

 black of the stigma » si apparent chez les individus matures. 



Au point de vue de la nervation, nous avons vu que, chez N. nobilis, 

 la série externe des nervules en gradin des ailes antérieures se com-
