 butterfly. I am certain, however, it was tlu' Tlniuiiiauli^ iioitiy,l,liii, of wliidi I had caught

Male. Whigs above dark chocolate-brown, fringe greyishdcliracious ; anterior wings with an oblique 

 blue fascia crossing wing a little beyond end of cell, and with three contiguous greyish-white subapical spots. 

 Wings beneath much paler than above ; anterior wings with three fasciix' crossing cell, a patch beyond 

 cell, and a large subaiucal triangular patch dark castaneous, the triangular j)atch is inwardly margined 

 with a greyish-white oblique fascia ; posterior wings crossed by two waved and narrow castaneous fascise 

 near base, the colour between which to about the median uervure is also castaneous, beyond the outer 

 fasciffi is a large subtriangular castaneous patch margined inwardly and outwardly with violaceous, and 

 coutaining two ocellated spots, the smallest situate between the subcostal nervules and the largest placed 

 between the two low'er median nervules, a small black marginal spot at anal angle and the base violaceous- 

 grey containing a dark castaneous irregularly formed spot. Body and legs more or less concolorous with 

 wings.

Hab. — Malay Peninsula; Perak (Kiinst. — Calc. Mus.) ; Singapore (Wall. — Westw. ). — Sumatra (coll. 

 Hewitson). — Java (coll. Dist.). — Borneo (Druce). 



The only specimen of this species which I have seen from the Malay Peninsula is in a tine 

 collection made by Kiinstler for Dr. J. Anderson, and which is here figured. 

 It will, in this enumeration, follow T. uouinldin.

This genus may at once be separated from Tlununnnth in a synoptical manner by tiie character of 

 the inner margin of the anterior wings, which is convex at base and then concavely sinuate to outer angle ; 

 the anal angle of the posterior wings is always rounded and never produced in caudate prolongation. The 

 first subcostal nervule of the anterior wings is emitted at about one-fourth before the end of the cell, and 

 does not anastomose with the costal nervure ; the second, third, fourth and fifth subcostal nervules are
