This is anotlier of the inauy species captured in Malacca by Capt. PiuwiU that have 

 apparently been met with by uo other collector. The ligure represents two such specimens 

 now contained in the British Museum. Fig. 19 is typical ; fig. 18 represents a specimen 

 catalogued as Hewitsou's species by Mr. Butler, and which may probal»ly lie hut a variety, and 

 is figured as such ? The original description is as follows : — 



"Underside. Male. — Anterior wing violet-blue: posterior wing brilliant morpho-hlue ; the tiKini'ms 

 hroad, dark brown." 



"Underside. Anterior wing with the,/7'rs/ tlirrr spots of tlie transverse baud iilrnvd ohl'uinchj (mlwurds, 

 till- two oiitcy spots a little within them und jilncal tr((nsrcrsdy." 



"Exp. li inch." 



HAB.^Malay Peninsula; Malacca (Pinwill — Brit. Mus.). — Sumatra (coll. Wallace — Hewits.). 



The different colour of the anterior and posterior wings readily indicates the identity of 

 this species, and, as remarked before, the so-called variety here figured, is only admitted 

 as such with hesitation, until a series of specimens can be examined.

Male. Wings above violaceous-blue, margins narrowly dark fuscous ; wings beneath brownish with 

 the following spots and fasciie margined with greyish ; anterior wings with two spots in, and one at end of 

 cell, two beneath cell divided by the lower median nervule, a slightly curved fascia between end of cell and 

 outer margin, which is strongly dislocated between the lower discoidal and upper median nervules (where 

 it has the appearance of a projecting spot),t a subcostal spot between the first and second subcostal 

 nervules and a narrow submarginal fascia ; posterior wings with six basal spots, two irregular central 

 curved macular fascise, dislocated and united into one from lower subcostal nervule to costal uervure, 

 a submarginal fascia and three marginal metallic greenish spots more or less marked witli black near 

 anal angle : apices of tail-like appendages greyisb-wbite. Body above and beneath with legs more or less 

 concolorous with wings. 



Female. Paler bluish above, the dark marginal shadings very broad on anterior wings at apex and 

 outer margin, and at apex of posterior wings ; wings beneath as in male. 



Exp. wings, S and 2 , 32 to 45 miUim. 



■■■■ In the specific nomenclature ot this genus several authors appear to have not only recof;uised the difliculty of 

 properly separating the species, hut to have also endeavoured to make it almost impossihle to rcmemher the names of 

 such species, by inventing a farrago of euphonious words, as though rhyme was the one thing needful. To this rhythmical 

 and labjTinthiau effect the following contributions may be acknowledged: — ' tiiuta,' ' einmiiia,'' ' am^'hiiiiuta,' * antimiUa,' 

 ' hijpomuta,' ' metamuta,' and "■ ycrimuta.' As these are all names of closely allied species, such " contributions to science" 

 require application and study. 



\ This has not been sufficiently shown in the figure ot the female here given, though it is distinctly indicated in 

 that of the male.
