Batracharta cossoides Walker
Carissa cossoides Walker, [1863] 1864, J. Linn. Soc. (Zool.), 7: 168.
Batracharta chariessa Prout, 1928, Bull. Hill Mus. Witley, 2: 261, syn. n.

Batracharta cossoides

Diagnosis. This and the next species have similarly obscured indigo brown patterning to the forewing, with more distinctly indigo patches basally and discally, but cossoides is generally larger, with the patches more widely separated and the marginal zone wider, more evenly marked, irrorated with yellow, brown and pinkish red. See also the diagnosis of the next species.

Taxonomic note. In the original description of chariessa, it is clear that Prout had not examined the holotype of cossoides, referring entirely to female material in BMNH attributed to cossoides. In fact, the holotype of cossoides (UM, Oxford) proves to be chariessa, so the other species is described as new below.

Geographical range. Borneo, Sumatra, Sulawesi.

Habitat preference. The species is infrequent, known from the type material, taken in Sarawak by A.R. Wallace, probably in the lowlands. Recently collected cossoides material is also all from lowland localities, the first two in Brunei: two from dry heath forest on sand at Telisai (15m); three from disturbed lowland forest at Labi (30-60m); three from Samarinda on the coast of Kalimantan.
