 three yards of the insect, I had only my gun with me, and therefore was unable to catch the 

 butterfly, I am certain, however* it was the Tkaumanth naweddin, of which I had caught 

 several in the same neighbourhood within the previous three or four days." '

Male, Wings above dark chocolate -brown, fringe greyiBa-ocuraceous ; anterior wings with an oblique 

 bloc fascia crossing wing a little beyond end of cell, ami with three contiguous greyish-white subapical soots. 

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

 cell, and a lar^e subapieal triangular patch dmk rnstinniiiih, the triangular patch ia inwardly margined 

 with a greyish-white oblique fascia ; posterior wings crossed by two waved and narrow eastaneous fasci*e 

 near base, the colour between which to nluntt. \\u- median nervure is also eastaneous, beyond the outer 

 fascia is a large subtriangular eastaneous patch margined inwardly and outwardly with violaceous, ami 

 containing two oceliated spots, the smallest situate between the subcostal nervines and the largest placed 

 between the two lower median nervules, a small black marginal spot at anal angle and the baae violaceous- 

 grey containing a dark eastaneous irregularly formed spot. Body and legs more or lees con colo roue with 

 wings.

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

 collection made by Kuustler for Dr. LMJerson, and which is here figured.

Tliis genua may at once be separated from Tkmmmth in a synoptical manner by the character of 

 the inner margin of the anterior wings, which is convex at base and then concave ly 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 



* A similar observation wu made by both Lftcordalre And Mr. l>nrwin in South America in reference to Ageronia 

 fct ouia. Mr. Dnrwiu wrote :— " Several tiiuW when a pair, probably male nod female, were chasing each other in an ii re^dur 

 course, ilicy natural within a few yarda of ine; and I distinctly heard a clicking noi*e, similar to that produced by a toothed 

 wheel pausing under n spring catch. Tin- itoise wan continued at short intervals, ami could be distinguished nt about twenty 

 yards distance: t our certain there is no error iu the observation" (.louru. Research, Nat. Hist. & Geol. Voy, Beagle, pp. ti'A -4, 

 18G0). Mr. Wallace also observed the same fact, and a* ho never heard the noiso made by the nruall upeciea of the germ* he 

 wa« iuclined to believe "that it ie produced in some way by the contact of two insect*, and that only the larger and stronger 

 winged species can Produce ii r'On ihe IIubitH of the llntterilies of the Anio/on Valley Trains. Ent. Soc. 1858).
