especially the bright silvery clothing, and even a faint 

 central wing-cloud, in common with Becker's species ; but 

 they differ greatly in that the eyes are long-oval and the 

 antennae are smaller. The thorax in the species represented 

 is black and not striped, and scutellar bristles are present. 

 They must form the African equivalent of the Asiatic genus. 



Head (see figs. 16 & 17) : — The facial and frontal tangent- 

 planes meet at about 120° ; eyes long-oval, with axis nearly 

 upright; jowls very deep, about half the depth of the long 

 eyes; antennae nearly as long as face, with a practically 

 rectangular 3rd joint about twice as long as broad, and a 

 very fine, slender, bare arista, thickened basally. Frons 

 parallel-sided, with a long rather narrow triangle from 

 vertex to front only just differentiated by its extra shininess 

 from the rest of frons. Wing-venation as fig. 18, the 3rd 

 and 4th veins just not reaching the edge. 



The whole insect is covered with brilliant shining white 

 hairs even on the frons ; these are very stout and bright on 

 the thorax and head, but less so on the abdomen. Unlike 

 Euryparia, there is a pair of scutellar bristles inserted in 

 the same manner as in Ops. 



The palpi are quite peculiar, being rather stout, long, and 

 spoon-shaped. 



Bathyparia ■pi'aeclara, sp. n. 



Head (top view) : — Chestnut-brown, the triangle more 

 shining ; the silvery hairs along the triangle^s border bend 

 across it ; eye-margins broad and very silvery ; the verticals 

 and ocellars white ; hind head all black except just on vertex 

 behind ocelli, where is a long yellowish stripe along the 

 vertical ridge. Side-view : — Similar in colour, the broad 

 hind eye-margin very silvery, as is the hind jowl. Antenna 

 slightly darkened brown ; arista pale at base. The palpi 

 are long, spoon-shaped, and silvery grey ; tongue dark. 

 Face the same brown colour, side-ridges well developed ; no 

 median keel, so that the antennae nearly touch basally. 



Thorax : dorsum, meso- and sternopleura all shining black 

 and punctate, covered with bright silvery-white hairs arising 

 from the punctures ; the rest of pleura bare. Scutellum 

 bright yellow, with approximated pale terminal bristles and 

 silvery hairs like thorax. Notopleura black and dull from 

 very faint shagreen. 



Wings (see fig. 18) clear, with brown veins; in several 

 specimens the central part is very faintly tinged with browu. 

 Halteres pale yellow.
