1893.] genus of satyrid butterflies. 5 



the apex of the forewing is more rounded, and the forewing has similar 

 fine marginal lines as are found in the hindwing of the male. This 

 species differs structurally from E. angularis in that the tooth or angu- 

 lation at the termination of the second median nervule of the hindwing 

 is as great or greater than that at the third ; in E. angularis this tooth 

 is quite small. 



In one specimen in my collection from the Pegu Toma, taken in 

 December, the markings are almost as prominent on the underside 

 as in E. angularis, there are two apical well-formed ocelli to the 

 forewing, and five ocelli to the hindwing, the discal bands well-marked, 

 but as the inner band of the hindwing is straight (not outwardly strongly 

 angled in the middle), and the outer band is once outwardly angled only 

 (instead of twice), I have no hesitation in placing this specimen under 

 E. rotundata rather than under E. angularis. Another specimen in my 

 collection taken at the same place and time is quite typical E. rotundata. 



In the Proceedings of the Zoological Society of London for 1891, 

 page 268, Mr. H. J. Elwes records E. medura, Horsfield, from East Pegu, 

 Upper Burma, and places E. angularis, Moore, with a query as a synonym 

 of that species, and makes the following remarks : — 



" Numerous specimens were sent by Doherty from East Pegu, 

 taken at about 1,500 feet [during March and April], of which several 

 females and one male were by him supposed to be, and marked as, a 

 distinct species. These correspond to the female taken in the Thoun- 

 gyeen forests by Major Bingham, and described by Marshall and de 

 Kiceville, ' Butt, of India,' vol. i, p. 237,* as nearer to E. medura of 

 Java than to E. angularis." 



" After examining the series closely and comparing them with one 

 Javan specimen, I do not see how to separate the two species \_E. medura, 

 Horsfield, and E. angularis, Moore], for, though in the supposed new 



* " A female taken in the Thoungyeen forests in March differs from our other 

 female specimens in the ocellus on the upperside of the foreuHng being very nearly 

 round, not oval, with a distinct yellow iris of equal width throughout ; the outer 

 fascia of the hindwing much broader and very distinct ; four large black spots 

 beyond twice the size of those in the other specimens, the yellow trades prominent 

 and touching. On the underside of the hindwing the two discal fascise have 

 almost disappeared, and the five submarginal ocelli are very minute. This speci- 

 men differs only in the following particulars from Horsfield's figure of E. medura : 

 The outer margin of the forewing is not quite so evenly rounded, being in fact 

 slightly concave ; the large ocellus is not quite so large as in E. medura, and the 

 iris is less wide. On the underside the apical ocelli on the forewing are smaller, 

 and on the hindwing the ocelli are minute, and the fascise are obsolete. This 

 specimen, however, is much nearer E. medura than E. angularis." (Marshall and 

 de Nice'ville, 1. c.)
