a good number of the species based on slight differences in the shape of the markings, 

 and on the red, yellow, or white colour of the hindwings, are mere aberrations.

7. Massaga angustifascia IJothsch. sp. nov. 



Female. — Upperside : all four wings black with an oily green gloss, the veins 

 being strong metallic green. Wings crossed by a single convex cream-coloured band, 

 situated about 1 millimetre beyond the cell of forewing, measured at the upper 

 median vein. The band on forewings stops at the costal nervure, where it is nar- 

 rowest, while it is widest at the discoidal nervules, being here a little more than 

 2 millimetres. At the apex of forewings the fringe is white, otherwise dark. 



Palpi, except third joint, head, anterior coxae, anterior femora, and prothorax 

 crimson ; tip of abdomen yellow ; rest of body oily green. 



Undem'tde of wings similar to above, but veins on hindwings from base to edge 

 of band of same colour as band. 



Expanse : forewing AM 29 mm. ; EM 15 mm. ; PM 21 mm.

Differs from virescens Butl. in the narrower band, it being uniformly wide on 

 lioth wings and well outside the cell, and in the cream veins on underside of 

 hindwings. \V. R. 



e. Indian forms vjith vein 10 of forewinrjs being stalked with 8 and 9. 



Here belong Chelonoinorjjha Motsch., Biirgeiia Wlk., and a number of new 



genera. 



Immetalia Jord. gen. nov. 



cJ ? . Front of the head scarcely with an indication of the usual conical processus, 

 without a circular ridge or with only a trace of it. Palpi almost naked, i.e. clothed 

 with short hairs, terminal joint at least three times as long as broad. Antennae a 

 third shorter than the co.stal margin of the forewings, distinctly clubbed in either 

 sex. Tibiae naked, or almost so. 



Neuration : forewing with vein 10 stalked with 8 and 9; vein 3 close to 4 from 

 hinder angle of cell ; 2 from near hinder angle of cell ; second partition of median 

 vein* shorter than the respective portion of the outer margin. Hindwings with 

 veins 3 and 4 together from lower angle of cell ; 2 from near hinder angle of cell, as 

 on forewing. 



Male with the anal segment large, and the upperside of the abdominal margin 

 of the hindwings clothed with long, often partly erect, hairs.

Comes nearest to Xanthospiiloptertj.r Wllgr., from which it differs in the longer 

 and naked terminal joint of the palpi, the less gilibose forehead, and in the 



? "Second partition" of the median nervure is ihe portion between veins 2 and 3,
