On Odonaia &c.from Upper Burma. Ill 



XVIII. — Xotes on a Small Collection of Odonata d)C. from 

 Upper Burma, with the Description of a new Species. By 

 W. F. KiEBY, F.L.S., F.E.S., Assistant in Zoological 

 Department, British Museum. 



Mr. DE Niceville has just forwarded a box of Odonata from 

 the Katha District of Upper Burma to the British Museum ; 

 as it proves to contain several species of considerable interest, 

 I have given a list of the whole. The dragonflies sent all 

 belong to the subfamilies Libellulinaj and Agrionina^, and 

 the box also contained three specimens of one of the Sialidas 

 — Chauliodus maculipennis , Graj — in better condition than 

 those previously in the Museum collection.

Brauer's original specimens were from Amboina, and he 

 described both sexes. The specimen from Mjsol in the 

 British Museum, which I noticed in 1889, is a male, 

 measuring 100 millim. across the wings. There are two 

 specimens, male and female, in the Burmese collection, which 

 appear to belong to the same species. The male measures 

 111 millim. across the wings, and is very slightly larger than 

 the female. They exhibit no important differences either 

 between themselves or from Brauer's description of the sexes, 

 except that the number of cross-nervures in the basal cell of 

 the fore wings and the number of cells in the triangle vary 

 a little. In the male the hind wings have a greenish cupreous 

 lustre, not mentioned by Brauer, over the deep reddish brown of 

 the basal two-thirds. In the female the orange-brown staining 

 of the fore wings extends to the lower basal cell and the lower 

 sector of the arculus ; but a little beyond the nodus it ceases, 

 except along the costal and subcostal spaces, but extends 

 again at the apex, as described by Brauer. On the hind 

 wing it extends obliquely downwards over the whole basal 

 half of the wing ; but the middle of this part of the wing is 

 much lighter, while towards the anal angle there is a slight 

 submarginal band of dark brown, almost confluent spots. 



C. Hartertij Karsch, from Sumatra, is certainly a distinct 

 species, according to the description, owing to the much 

 smaller number of cross-nervures in the costal and subcostal
