Sp. 4. Bombycella? Alis rotundatis obscure hyalinis lividis, fusco irroratts. 



(Exp. alar. 6— 6^ lin.) 

 Ti. Bombycella.? Hillmer.—Fvi. Bombycella. Steph. Catal. No. 6038. 



Antennse with the shaft yellowish, the radii dusky-brown : front hairy, slightly 

 ochraceous: thorax and abdomen dusky: wings rounded, obscurely trans- 

 parent, of a Hvid brown, with darker fuscous spots, the margin rather dusky, 

 with a deep yellowish-gray fringe. 



Apparently very rare : I have two specimens, one of wliich I 

 obtained from Mr. Marsham's collection, the other from a dealer. 

 Mr. Haworth has .specimens of his own taking. 



Sp. 5. pectinella. Alis rotundatis cinpreo-fuscis, hyalinis, immacidatis, margine 



brunneo. (Exp. alar. 6 lin.) 

 Bo. pectinella. Fabricius. — Fu. pectinella. Steph. Catal. No. 6039. 



Antennae dusky-brown, with the radii palest : front hairy and dusky : thorax 

 and abdomen fuscous : wings rounded, immaculate, transparent ashy-brown, 

 with a narrow darker margin, the nervures dusky, fringe yellowish-gray. 

 Also rare. I possess one specimen, which I obtained from Mr. 



Francillon's collection. Mr. Haworth has one, which he purchased 



of a dealer. 



Genus LXXVII. — Nudaria, Haworth. 



Palpi minute, curved upwards, squamous, triarticulate, the two basal joints of 

 equal length, the terminal minute, cylindric : maxillce longer than the head. 

 Antennce simple in both sexes, ciliated beneath in the males ; the basal joint 

 robust, elongate, with a dense hairy tuft : head with a dense fascicle of hairs 

 between the antennae : thorax not crested : abdomen pilose, slender in the 

 males, with a tuft at the apex, more robust in the females, the tip rather 

 conical : wings slightly deflexed, more or less elongate, rounded posteriorly, 

 diaphanous, pilose : legs rather slender, naked, the two posterior joints with 

 spurs at the tip. Larva exposed, hairy ; pupa obtuse. 



Nudaria has the wings remarkably transparent, and may be 

 known from the rest of the Arctiidae (except Hypercompa) by the 

 length of its maxillse, which considerably exceeds that of the head : 

 the antennae are simple in both sexes, with the basal joint remark- 

 ably large and ovate, and the palpi are minute and squamous : their 

 flight is nocturnal. 



Sp. l.mundana. Alis subhyalinis, lutescente-alhidis strigis duabtis undatis punc to- 

 que medio fuscis. (Exp. alar. 9—1 1 lin.) 



Ph. At. mundana. Liime.—'Nu. mundana. Steph. Catal. No. 6040. 



Antennae ochraceous-brown ; head, thorax, and abdomen woolly grayish-white : 

 the anterior wings lutescent- white, with two undulated fuscous strigs, one
