57. (2) Castnia personata. " Eusca, aureo viridi micans, subtus flava ; antennse apice 



flavescentes ; abdomen subauratum vittis duabus ocbraceis : alas cervinse, sat angustse, 



lituris nigro-fuscis, fascia marginali flavescente maculata; anticse vitta discali, 



strigas quatuor ernittente, posticse vittis duabus parallelis extus abbreviatis. Nearly 



allied to C. linus. Length of wings 36 lines." — Walker. 



The above description is unintelligible, as may be seen by M. Boisduval's attempt to 



translate it into French, and by his inability to perceive its apparent identity with his 



Gazer a simulans. The general colour of the four wings is obscure luteous, with black 



markings ; these consist of an oblique patch, arising on tbe costa before the middle, 



dilated towards the middle of the wing into an elongated patch ; beyond the middle of 



the costa is a broad oblique band reaching to the middle, followed by four more distinct 



luteous longitudinal spots preceding the broadly black apex ; the inner margin is dusky : 



the hind wings are rather lighter luteous in the middle of the disk ; the costa, a central 



bar, and the apical margin black, the latter with four white dots on its inner edge near 



the outer angle. Expans. alar, antic, lin. 36.

This species is nearest allied to C. ecuadoria, with which the arrangement of the cell 

 and branches of the postcostal vein of the fore wings nearly agrees ; but the transverse 

 vein closing this cell is longer, in consequence of which the branches 3 and 4 arise 

 wider apart. 



59. (4) Castnia ckatina. (Plate XXXII. fig. 4) Alis anticis oblongo-ovatis apice 

 subrotundatis fulvis ; striga costali prope basin, altera subcostali tertiaque multo 

 majore prope marginem internum, striga undulata obliqua discoidali, macula rotunda 

 media cum margine antico connexa, plaga magna obliqua inter medium et apicem, 

 limboque apicali dentato nigris ; alis posticis aurantiaco-rufis, striga subcostali, fascia 

 lata media e margine anali fere ad angulum externum extensa limboque dentato 

 nigris ; capite albo maculato, collo lato fulvo fascia transversa tenui flavida ; abdomine
