Doherty, from Margherita and Sadiya in Upper Assam, and P. fruhstor- 

 feri, Snellen, from Java. P. callineura appears to be a very variable 

 species not only in colouring but also in size, as our specimens 

 measure in expanse of wings from 1*15 to T75 inches. In Sumatra it 

 is common in the forests of the outer hills south of Namoe Oekor 

 throughout the year. It settles with folded wings. It requires a skilled 

 eye to distinguish it when at rest from common species of Padraona or 

 Telicota. 



685. Plastingia Helena, Butler. 



Hagen. Is much rarer than the last-named species, but occurs 

 throughout the year from Selesseh to Bekantschan. 



686. Plastingia vermicdlata, Hewitson. 



P. vermiculata, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 56, n. 47, pi. v, 

 fig. 15, male (1894). 



Hewitson. Grose Smith. Originally described from Sumatra ; 

 occurs in the Battak mountains near Bekantschan in July rarely, only 

 two or three specimens obtained. 



687. Plastingia tessellata, Hewitson. 



Originally described from Macassar in Celebes. The markings of 

 the underside are stated to be " yellow." The " Hesperia " eulepis of 

 Felder, described also from Celebes, is said to have the markings on 

 the underside " oehraceo-sulphureis," and is almost certainly a synonyni. 

 The next-named species is given by Captain Watson as a synonym also, 

 but it has the markings of the underside " pure silvery white." I be- 

 lieve it to be distinct. P. tessellata is very rare, two or three specimens 

 only have been taken near Bekantschan in July. 



688. Plastingia naga, de Niceville. 



Hesperia ? naga, de Niceville, Journ. A. S. B., vol. lii, pt. 2, p. 89, n. 37, pi. x, 

 fig. 2, female (1883). 



Occurs at Sibsagar in Upper Assam, Singapore, N.-E. Sumatra, and 

 Java. Not less rare than the two foregoing species, four or five speci- 

 mens only obtained in March, June and December. Dr. Martin caught 

 it himself commonly in Singapore in February, 1S95.
