PABAGrS. CHRYSOGASTER. 1 



joint only dark brownish at the base beneath, very elongate, longer 

 than the" arista, which is black. Thorax, scutellum, and halteres 

 as in the preceding species ; the abdomen also, but with longer 

 hair, which forms distinct bands at the base of each segment. 

 Leirs reddish, with the tips of the femora and the bases of the tibise 

 yellow ; hind femora darkened at the base, but not black. Wings 

 hyaline, with black veins and bkck stigma ; pubescence as in 

 P. mai'sliaUi. 



Type $ , a single specimen, from Marsabit, Brit. East Africa, 

 21. ix. 1911 (E. J. Stordy). 



6. Paragus tibialis, Fallen, var. substitutes, Loew (1858). 



A single male specimen from Durban (_F. Muir) belonging to 

 this variety of the little European species, which is, however, 

 hardly distinguishable from the other forms of this variable 

 insect. 



Genus 2. CHRYSOGASTER, Meigcn (1800). 



It seems very remarkable that of this genus there are no 

 described species from the Ethiopian Region, with the exception 

 of the very aberrant Chrysoyaster (Orikoneura) pcecilophthalma, 

 described by me in 1908 from Erythraea, which, on account of 

 its hairy eyes, seems to be in a very isolated position. The genus, 

 however, is probably fairly well represented in Tropical Africa ; 

 perhaps the species have been neglected on account of their small size. 



The collection before me contains examples of three very inter- 

 esting species, which belong to the subgenus Orthoneura and have 

 bare eyes ; they may be tabulated as follows : 



1 (2) Wings without any dark pattern ; eyes 



marked with confluent brown spots; third 

 antennal joint rather short ; body elon- 

 gate, metallic green, but not very shining, 

 the abdomen dull black in the middle . . pcsdlops, sp. n. 



2 (1) Wings with definite dark pattern : eyes uni- 



colcrous or banded ; body broadly ovate, 

 very strongly shining. 



3 (4) Third antennal joint rather short; abdomen 



adorned with a broad velvety black band 

 on the middle of each segment ; legs 

 entirely black : wings with many black 

 spots towards the apex ; eyes uuicolorous. spiloptcra, sp. 11. 



4 (3) Third antennal joint very long, linear; 



abdomen in the middle as strongly shining 

 as the rest of the body, with a black band 

 on the second segment alone ; legs in 

 great part yellow ; wings with only a 

 perpendicular brown band before the 

 tip ; eyes with two perpendicular brown 

 bands Iteviyata, sp. n.
