 minute black spots below the internal nervure. Transverse band

 hind margin as on the upperside. The nervules and iuternervular 

 markings are somewhat darker.

Fam. Lyc^nid^. 



Genus Castalius. 

 Castalius margaritaceus, sp. n. (Plate XLVIII. fig. 3.) 



Intermediate between C. carana, Hew., and O, lactinatus, Butler. 



Fo7'e wing. Creamy white ; the base, costa, apex, and hind margin 

 broadly marked with black, with no indication of white near the 

 apex as in C. carana. A small streak of black extends from the 

 costal margin along the end of the discoidal cell. 



Hind wing. Closely resembling that of G. lactinatus. The sub- 

 marginal black border consisting of six white spots with black 

 ocelli, each separated by the black nervules ; these spots are rather 

 pointed towards the base. There are a few black spots beyond 

 this border, and a slight shading of black at the base. 



Underside. Differs very much from that of either species. 



Fore wing. With a black streak close to the base, followed by two 

 small black spots, one above and the second below the median 

 nervure ; a minute spot and streak at the end of the discoidal cell ; 

 two submarginal rows of black spots, commencing from the costal 

 margin and gradually uniting above the submedian nervure. The 

 i-ow of white subovate spots is very distinct, each having a small 

 black centre. 



Hind wing. Similar to the fore wing, but having a few more 

 spots near the base ; the black streak at the end of the cell is visible 

 as in the fore wing, also the two submarginal rows of black spots, 

 though more broken, and the subovate spots of white have larger 

 centres with silvery-green ocelli. 



Expanse 1 inch.

Genus Hyreus. 

 Hyreos cordatus, sp. n. (Plate XLVIII. fig. 4.) 



Nearest to H. juba, Fabr., but at once distinguished by the 

 heart-shaped patch of black velvet near the apex.
