striated lougiturlinally with black. Hind femora with the 

 externo-median area very narrowly marginated with black 

 along the basal half of the upper carina, and a series of 

 minute black dots along the outer margin of the upper outer 

 area ; the knees black on the inner side, except the apex of 

 the lobes, and with a semilunar black spot on tlie outer side. 

 Hind tibiae with the base very narrowly black, the rest dirty 

 blue ; their spines white with black tips. Hind tarsi reddisli 

 brown below, blackened above. 



? (paratype). The postocular fascia of the head pro- 

 longed along the upper third of the lateral pronotal lobes 

 and the discoidal field of the elytra, where it gradually dis- 

 appears halfway to the apex^ not blackish castaneous, as in 

 the male type, but olivaceous green. The puncturation

Described from two males and six females from Entebbe, 

 Kivuvu, and Mabira Forest, Uganda (C. C. Gowdey). 



Easily recognised by the numerous colour-characters, 

 especially by the coloration of the hind femora and tibiae, as 

 well as by the lateral fascia, which is not known in any of 

 tl»e previously described species. The species occurs in two 

 colour-forms, and the type and paratype described represent 

 both of them ; the difference is not sexual, but individual. 



With regard to the synonymy of the genus Tristria^ Stal, 

 I should mention that both Metapula of Giglio-Tos (Boll. 

 Mus. Torino, xxii. 1907, p. 10) and my Tapinophyma (Ann. 

 & Mag. Nat. Hist. ser. 9, vol. vii. 1921, p. 496) are pure 

 synonyms of Tristria. 



3. Eucoptacra gowdeyi, sp. n. 



^ . Antennae reaching a little beyond the hind coxae, com- 

 pressed at the base, the rest distinctly incrassate. Face very 

 coarsely and densely punctured ; frontal ridge flat, coarsely 

 punctured, with the margins smooth, parallel-sided below 

 the ocellum, regularly elliptically dilated above the latter, 

 narrowing again at the fastigium ; widest between the an- 

 tennae and there about twice as broad as the subocellar part ; 

 its width at the fastigium slightly more than the subocellar
