many of them mite-eaten, yet being from good localities I de- 

 termined to go through them all, and the result has well paid 

 me for the trouble. Amongst the duplicates from Buxar I 

 found a number of butterflies of the genus Euthalia, which 

 looked when in the envelopes like males and females of E. 

 ajypiades, a common insect in Buxar, but as they did not 

 correspond with the Buxar specimens in my collection I had 

 them all set up, and find I have a nice series of E. halarama 

 male and E. sedeva female. I have brought for exhibition to 

 this meeting six of the males and three females (the others I 

 have given to Mr. Moore) ; also seven males and six females 

 of E. appiades (two males and one female from Buxar, and 

 the rest from Sikkim). I have also made rough enlarged 

 drawings of both species. I think, after examining these- 

 specimens, no one can for a moment doubt that E. sedeva and 

 E. halarava are sexes of one and the same species, and that 

 though closely allied to, it is quite distinct from E. appiades. 



Above the specimens of E. halarama from Buxar I have 

 placed a broken specimen of that species, received from Mr. 

 Moore, labelled ' Silhet.' This is a co-type, and it will be 

 seen that all the Buxar specimens are identical with it. The 

 type of E, sedeva is a unique specimen in Mr. Moore's 

 collection : it is very well represented in his plate, and my 

 specimens are identical with it. The chief character in 

 E. sedeva is the large white subapical patch on the fore wings, 

 on the borders of which the double discal band expands, after 

 being very much contracted around a small white spot in the 

 lower radial interspace ; this character is constant in all the 

 male examples of E. halarama, and although the patch is not 

 white it is there, and can be distinctly seen both on the upper 

 and under sides, whereas in E. appiades the outer band is 

 straight and the inner one only slightly bent in the lower 

 radial interspaces ; there are also diflferences in coloration 

 below, but they are not of so much consequence."
