while others are dark green insects like parthenos. Intermediate forms 

 are common. 



27. Cethosia pbnthesilea, Cram. 



Sumba and Sambawa, common, even on the coast. A single female 

 taken in the interior of Sumba was very large and richly coloured, re- 

 sembling the ievciale of the Javanese G. hypsea, Doub., but I am not 

 sure that it was distinct from G. penthesilea. 



Cethosia tamboea, n. sp. 



Black, the usual wavy submarginal lines absent on both wino-s, 

 Forewing with an irregular ochreous subapical band of six marks, the 

 first two slender, minute, the third elongate-quadrate, the fourth very 

 small, triangular, the fifth long and narrow, the sixth large, triangular, 

 paler ; a dull reddish area on the hind margin and basally in the interno- 

 median space, two or three reddish touches basally in the cell. Hind- 

 wing, basal half red, a small dark spot discally between the costal and 

 the subcostal veins, and one between the subcostal branches. Below, 

 all blue-black and ochreous-white, except a reddish area on the hind 

 margin of the forewing. 



The description, which is apparently that of a female, is a poor 

 one, but I believe several specimens of both sexes are in Mr. Neumoe- 

 gen's possession. It is very unlike any known species. 



Sambawa, mountains, scarce. I have named it after the great Sam- 

 bawan volcano, celebrated for its eruption in 1815. 



I have dubiously recorded a similar species in Sumba, not taken, 

 the underside more variegated. 



Two very beautiful species, G. lamo.rcJcii and leschenaultii, were 

 taken by Mr. Wallace in Timor, but neither seem to extend further 

 westwards. 



28. CuPHA ERTMANTHis, Drury. 



Sumba, Sambawa, normal. Ko Cirrhochroa was seen in either 

 island, nor has any been recorded from Timor, 



29. Atella phalanta, Drury. 



Sumba, Sambawa. Sumba specimens are richly marked with 

 purple below. 



30. Atella sinha, Kollar. 

 Sumba, Sambawa, normal,

Two tattered specimens from Pada Dalung in Sumba seem to be
