Mr. Moore has discovered that the insect figured by Felder* as his /•;. (jrotei is really the 

 female of another species he had previously described as E. harrisi. The name of the ]\hilay 

 butterfly must therefore be altered as above. 



18. Euploea marsdeni. (Tab. XXXIX., tig. 1 <? .) 



TniiKja niarsdcin, Moore, Proc. Zool. Sec. 1883, p. 2CG, n. 3. 



The following is Mr. Moore's description of this species : — 



"Intermediate between T. brcmcri and T. cramcri.^ Colour paler. Fore wing more the shape of 

 that in T. cramcn, being comparatively longer and narrower than in T. bremcri ,- the markings also are 

 more like those in T. craineri, there being only two small upper submarginal spots, which, however, are more 

 elongated and narrower, the next (or largest) spot is also much longer and narrower, the fourth smaller, 

 and the lower three very small ; the marginal row is distinct but very small ; hind wings with two rows of 

 small distinct white spots." 



Exp. wings, ^ , 98 millim. 



Hab.— Malay Peninsula; Singapore (coll. Moore; Kerr — coll. Dist.). 



I have given Mr. Moore's original description, because the species is evidently a variable 

 one, as in two male specimens sent me, by Capt. Kerr, from Singapore, one (the si)eciniou 

 tigured) possesses three small pale spots beyond the cell, and a very small spot in the cell, 

 which are altogether absent in the second example. 



I systematically place E. viargdeiti as following E. hrmicri.

Mr. Butler states that " the true M. leda is a totally dissimilar Amboinese species," and 

 proposes the name M determinata for the common Indian and Malay form of the species. 



I do not agree with this course, firstly, because Mr. Butler himself does not seem clear as 

 to what is the typical form, as, though he would now restrict that form to Amboinese examples, 

 he has previously stated that he " found the small dark form (the true I'. Leda of Linnaius) to be 

 almost exclusively confined to India"; ^ and, secondly, because I possess Amboinese specimens 

 of the species collected by Mr. Forbes, and find nothing but the gradual variation previously 

 described by Mr. Butler himself in the paper referred to, thus provhig his also previously 

 expressed words, "I am fully convinced that this species is capable of almost any amount of 

 variation in form as well as in colour." § 



It has been already stated {antra, p. 40) that M. Irda and M. immc have often Ijceu 

 considered as varietal forms of one species. Mr. L. de Niceville has subsequently informed us 

 that M. ismenc is but the dry-season form of M. Irda, \\ the species thus exhibiting seasonal
