differ greatly from Euchaetes. The head is relatively smaller than in 

 Euchaetes and held freer from the thorax. The scaled male antennix; arc 

 bipectinate, dependant at the tips and are shorter, the pectinations lon- 

 ger than in Enchaetes. The antennus thus reminds us of the succed- 

 ing Dasychirid Group. We have counted thirty three (33) pairs of 

 these pectinations. In the female the pectinations are reduced so that 

 the antennus appears simple; it is provided with setal hairs. The 

 smooth and closely scaled legs are rather long and slender, the tarsal 

 joints hidden by the close s(|uaujation. The hind femora are provided 

 with two pair of short spines ; one, the shortest, at the apex of the joint ; 

 the second, beyond or without the middle. The femoral spurs are 

 shorter than in Euchaetes. The female abdomen is short and plump, 

 reminding us of certain Lithosiid genera. In the male it is slender, 

 but hardly exceeds the aual angle of the secondaries in length. 



The wings widen outwardly more than usual ; hence the outline is 

 not dissimilar to Ameria and other Lithosian genera. However the 

 neuration differs essentially. In Ameria and Euphanessa we have a 

 small triangular supplementary cell formed above the discal cell, and 

 a different plan of costal nervulation. From these, Vanessodes and 

 Euchaetes both differ. lu the present genus the subcostal uervure 

 emits two superior nervules which join the costa before th,e apex. 

 Beyond these, two inferior nervules are thrown off from the nervure 

 to the external margin below the apex. The extremity of the s. c. 

 nervure is shortly furcate at the apex of the wing. The course of the 

 median nervure and nervules differs from Euchaetes, in which the 1st 

 2d and 3d m. nervules arise together. Here the 1st, 2d and 3d are 

 thrown off at intervals, the discal cell is open. Here is no median fold 

 as in Ameria and Euphanessa. The open discal cell of the secondar- 

 ies is propiirtionaJly longer and narrower in Vanessodes than in the 

 two last mentioned genera ; so that the m. nervules are shorter and 

 the whole wing narrower. The four m. nervules are thrown off as on 

 the primary at unequal distances and again at variance with Euchaetes 

 in this respect. The submcdian fold is wanting or very slight in 

 Vanessodes, in which there are two inferior nervures. 



Vanessodes clarus has the four wings immaculate and concolorous 

 above and below, while the nervules are a little darker. The tint is a 

 deer or mouse color. The head behind, a few scales at the base of the 

 fore wings and tlie abdomen above are soft yellowish. Beneath, thcr 

 abdomen, legs, palpi ami fnmt are a little darker tlian the wings, as is 

 the thoracic disc above. It expands from 22 to 24 uiillemetres. Al-
