340 Records of the Indian Museum. [Vol. VIII, 



The thorax also is of a briUiant green, with a black median 

 stripe, a pair of humeral bands and a lateral stripe on either side 

 also black. 



The abdomen is blackish above, with large auricles on the 

 second segment. It is much constricted from the commencement 

 of the third segment, and has blue-green markings. 



A. race of this species, nigripes, de Selys, has been recorded from 

 * Thibet,' and figured by Martin. This race would appear to be 

 much less brightly coloured than is the typical form. 



30. Gynacantha sp. sp. 



3 9 9 . _ 



I 9 , lo-viii-io. Very immature and in bad condition, is in all 

 probability a female of G. khasiaca, MacLachlan. The wings are 

 tinged with saffron at the base and apex. The length of the hind- 

 wing is 46 mm., the upper pair of terminal abdominal appendages 

 are short, slender and po nted, scarcely so long as the ninth seg- 

 ment ; the thorax gives indications of having a similar colour 

 pattern to that of the male. 



The two other females referable to this genus are also in a 

 state which makes it impossible to describe them. They are 

 possibly referable to G. hyahna, de Selys, but rather small for that 

 species, the hind-wing having a length of about 41 mm. The 

 upper pair of terminal abdominal appendages, broken in one 

 specimen, are in the other long, about twice the length of the ninth 

 segment, and leaf-like. 



These specimens tire dated 5-vi-io and Dejoo, 19 10, respec- 

 tively.

The specimen belongs probably to an undescribed species, but 

 its condition does not admit of a satisfactory description.

The range of this species will probably serve to delimit the 

 Burmese region from the Malayan, the latter characterized by the 

 closely allied V. amoena, de Selys.
