" Ochreous, pubescent : antennae piceous, slightly annulated with ochre, the 

 basal joint long, stout, and very hairy ; wings very pale fuscous ; superior 

 (anterior) subochreous, with numerous indistinct whitish dots." — Curtis, I. c. 



I know not this species, nor its locality. 



Genus XXIII.— MORMONIA, Curtis. 



Antenna; approximating at the base, rather longer than the wings, the basal 

 joint robust, considerably elongated, very pilose, and the two parallel and 

 porrected, the apical joints very slender : palpi moderate, maxillary in the 

 males porrected, slightly clavate and thickly clothed with short hairs; 

 labial slender : head small, very pilose : ei/es globose, rather prominent : 

 thorax densely hairy : luings moderately ample, anterior somewhat ovate- 

 Janceolate, and rather diaphanous, with few or no transverse nervures, 

 especially on the inner margin, towards the base of which is a patch densely 

 clothed with longish erect hairs ; posterior rather small : abdomen shortish 

 and robust : legs slenderish : tibice all furnished with a pair of spurs at the 

 apex, the two 'hinder ones each with a second pair below the middle. 



These insects may be known by having the antennae placed some- 

 what closely at their origin, and by their slenderness, the great 

 length and hairiness of the basal joint, pilosity of the head, and 

 brevity of the palpi in the males, and their slenderness in the
