refered to g. Diasemopsis Rond. All the species of Diase- 

 mopsis that are known until the present were found in Africa. 



Prom the fauna of the Sunde islands only recently an 

 interesting species, Teleopsis rubicunda V. d. W u 1 p., was des- 

 cribed; it has short setae on the scutellar spines, but for its 

 mesothoracic spines and general aspect it must be referred to 

 g. Teleopsis Rond. 



It must be here mentioned that in the number of genera 

 related to Diasemojjsis the genus Hexechopsis Rond. (type 

 Diopsis beccarii from Eritrea) was also named on account of the 

 setae of scutellar spines - being present in it. This genus was 

 afterwards taken to be synonymous to Sphyracephala Gray by 

 s t e n-S a k k e n, this genus being altogether distinct and 

 characterized by the presence of alulae. 



It appears that Rondani himself consented to this trans- 

 position, as in his list of Diopsidae of 1907 we find D. bec- 

 carii under the name of Sphyracephala beccarii Rond. The 

 genus Hexechopsis may, therefore, be considered as super- 

 fluous. The genus Sphyracephala is represented in the African 

 fauna by one more species Sphyracephala africana Karsch 

 from East Africa. Other genera of Diopsidae, except those 

 mentioned, are not met with in the African fauna.

To this species I refer several specimens which, although 

 being somewhat unlike, are connected with each other by tran- 

 sitory forms, so that a strict demarkation cannot be drawji 

 between them. The sexes also differ from each other. But 

 several characters of this very variable species are repeated 

 which points to a specific relationship between the insects 

 described. 



Length oi d(^ 5V2 — 7 mm. ?? 4^/4— 6V4 mm. 



Width of head with eye-stalks in cT 5 — 8 mm., in $ 3'/2 nim. 



The species is related to D. aethiopica Rond. Head with- 

 out spines, dark brow^n. Frons-dark, black-brown. The eye- 

 stalks are of a dark colour as the front. The eyestalks vary 

 greatly in length and are especially long in males. 



Thorax black, with a slight gray tint. Neck and scutellum 

 black. The scutellum exceedingly narrow posteriorly. Its spines
