androconia." This hardly expresses the facts of the case, as will be at 

 once seen by a reference to Mr. Elwes' figure 4. The " male-mark" is 

 not li free from blue scales," but is composed of blue scales, but they 

 appear to be placed at a different angle to the other blue scales on the 

 wing, and they are not of the same shade of blue, being, indeed, quite 

 purple in some lights. Mr. Elwes quite correctly points out (probably 

 from a note of the capturer of the type specimens, Mr. W. Doherty), 

 that it has only two branches to the subcostal nervure in the fore- 

 wing. In the male the blue coloration of the forewing on the upper- 

 side is somewhat variable, in specimens from the same locality it is 

 more extensive in some than in others, sometimes almost reaching the 

 anal angle, sometimes far removed from it. 



On a closer examination of the pair of specimens of Tajuria mantra, 

 Felder, teste Moore, taken by Dr. John Anderson in the Mergui 

 Archipelago, Lower Burma, in the cold weather of 1881-82, and now 

 deposited in the Indian Museum, Calcutta, I find that one specimen 

 only (the female) is true T. mantra, the other (the male) being 

 B. cleoboides. T. mantra is a much larger species, has a much darker 

 ground-colour on the underside, and the discal linear fascia is placed 

 much nearer the outer margin than in B. cleoboides. 



Mr. G. F. Hampson writes to me as follows regarding the type 

 specimen of " Iolaus" isceus, Hewitson,* from Sarawak, Borneo : — 

 " The figure should be of a darker shade of blue, as in the male of 

 Tajuria longinus, Fabricius ; the discal line on the underside of both 

 wings should be more continuous, broader, and fulvous ; reduced to 

 obliquely-placed fulvous streaks above the anal yellow patch in the 

 hindwing. The * male-mark ' consists of a large patch of roughened 

 scales filling the whole outer part of the discoidal cell of the forewing 

 on the upperside, and extending rather beyond its limits. There are 

 no tufts of hairs between the wings. The forewing has only two 

 subcostal nervules." This note and a study of the figure leads me to 

 believe that this specimen is the same species as the B. cleoboides of 

 Elwes ; Hewitson's name isceus will however stand, as the female 

 specimen he first figured as that species is of a different genus to the 

 male specimen he subsequently figured as the opposite sex of his
