augles outwards, and the two reddisli-browii longitudinal lines proceed 

 from it to the outer margin of the wing.

DASYLOPHIA* nov. gen. 



Vertex of the head with two erect high acute tufts, the tips of which 

 meet over the vertex reaching to the level of the thorax in 9 , a little 

 shorter in S • Antennae with long slender pectinations on the basal 

 two-thirds, while the remaining third is provided with lateral set:« ; in 

 9 simple. Palpi slightly ascending; 3rd joint passing beyond the 

 front, 2nd joint slightly curved upwards, scales beneath the joint being 

 short; 3rd joint is half as long as the second, porrect, being directed 

 forwards at a slight angle with the 2nd joint. 



Thorax short, scales of the prothorax distinctly marked. 



Fore-wings hardly one-half as long as broad ; costa very slightly con- 

 cave in the middle, towards the tip a little convex ; outer margin 

 oblique; internal angle obtuse, the inner edge near the base of the 

 wing is full in ■£ , in 9 straight. 



The costa of the hind wings is long and straight; apex subrectan- 

 gular, from thence the outer margin is longer than usual and slowly 

 rounded to the not very distinct internal angle. The wings reach to 

 the basal two-thirds of the abdomen. 



Legs pilose, the anterior femora densely pilose, in 9 longer, and 

 more irregularly and thinly pilose. Abdomen long cylindrical, with 

 lateral tufts, and tip of I slightly tufted. 



In coloration the species are generally gray, with dark streaks run- 

 ning parallel ti the nervules; there is a distinct basal longitudinal 

 mesial streak, and an outer very distinct geminate curved line. 



The long slender acute palpi, the high vertical conical tuft, the slight 

 concavity of the basal two-thirds of the costa of the fore-wings, and the 

 long slender cylindrical abdomen of the S will distinguish readily the 

 species of this genus.
