1886.] Lepidoptera of Gachar. 347 



In the hindwing, tlie same inconstancy obtains in tlie two series of 

 spots on the margin : in some specimens both are as prominent and as 

 complete as in South China specimens of E, alopia, Godart, between which 

 condition of completeness and the defect of all but two or three apical 

 spots of the inner series there is every gradation in both sexes. One of 

 the female varieties has been described by Mr. Butler as E. grantii* from 

 Cachar, but, as the above remarks show, E. Iclugii is one of the most 

 variable of butterflies, so much so that some specimens of it are almost 

 if not quite indistinguishable from some specimens of E. kollari, while its 

 extremes are so very distinct that the one is brilliantly shot with blue, 

 and the other exhibits only a trace of this interference colour in certain 

 lights. The underside is quite as variable as the upper, and, in a single 

 Upper Burma female, there is a prominent violet-white spot in the 

 discoidal cell of the forewing, visible above and below. 



Following the principles of division adopted by Mr. Moore in his 

 " Monograph of Limnaina and Euploema,"^ we could make almost as 

 many species as there are specimens in it out of our large series captured 

 in Cachar under circumstances that leave no room for doubt that we have 

 to do with a number of individuals of a single variable species. We 

 have, therefore, abandoned the attempt to split up our specimens into the 

 several species discriminated by Mr. Moore in the Fademma group. 



11. EuPLCEA (Pademma) erichsonii. 



E. erichsonii, Felder, ReiseSNovara, Lep., vol. ii, p. 324, n. 444 (1865) ; E. crassa, 

 Butler, Proc. Zool. Soc. Lond., 1866, p. 278, n. 31. 



One female 6th April. This specimen has the submarginal spots on 

 the upperside of the forewing reduced to five large ones at the apex, and 

 the blue gloss confined to the dark base of the wings. 



12. EuPLOEA {Isamia) rogenhoferi. 



E. rogenhoferi, Felder, Reise Novara, Lep., vol. ii, p. 325, n. 446 (1865) j E. splen- 

 dens, Butler, Proc. Zool. Soc. Lond., 1866, p. 272, n. 9. 



Three males and a female, from April to June. 



13. EuPLCEA {Stictoploea) binotata. 



Stictoploea linotata, Butler, Journ. Linn. Soc, Zoology, vol. xiv, p. 302, n. 7 

 (1878). 



Two pairs taken in May and June. Mr. Moore (Proc. Zool. Soc. 

 Lond., 1883, pr). 319, 320) records two " new species " of this group 

 from Cachar. From the descriptions they must be very close to E. binO' 

 tata^ which itself is probably inseparable from E. hopei, Felder.
