PARAGUS.—CHRYSOGASTER. 15 
joint only dark brownish at the base beneath, very elongate, longer 
than the arista, which is black. Thorax, seutellum, and halteres 
as in the preceding species; the abdomen also, but with longer 
hair, which forms distinct bands at the base of each segment. 
Legs reddish, with the tips of the femora and the bases of the tibi 
yellow ; hind femora darkened at the base, but not black. Wings 
hyaline, with black veins and black stigma; pubescence as in 
P. marshalli. 
Type 9, a single specimen, from Marsabit, Brit. East Africa, 
2¥. 1x 1ST AS. Stordy). 
6. Paragus tibialis, Fal/én, var. substitutus, Loew (1858). 
A single male specimen from Durban (Ff. 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, Aeigen (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 Chrysogaster (Orthoneura) pecilophthalma, 
deseribed by me in 1908 from Erythrea, 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 Hinlonion dull black in the middle .. pecilops, sp. n. 
2 (1) Wings with definite dark pattern ; eyes uni- 
colorous 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 ihlacis 
spots towards the apex; eyes unicolorous. sptloptera, sp. n. 
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 brow n band before the 
tip; eyes with two perpendicular brown
