388 Mr. C. G. Lamb on 



in Scatophila; meanwhile the generic name Synhoplos is 

 proposed for these two new semiapterous Ephydrids. 

 The description of the new species is as follows : — 



Oedoparea oblita, n. sp. 



As mentioned above, the three specimens of a Phyco- 

 dromi may be provisionally placed in this genus. To 

 facilitate description, the insect is compared with the 

 well-known Oedoparea buccata, which very exceptionally 

 reaches nearly the size of the present insect. To avoid 

 repetition of name the contrasting characters of the latter 

 species are placed in square brackets, thus [ ]. 



$. Head : top view : — frons quite flat with no ocellar tubercle, 

 widening slightly to the overhanging forehead, all dull orange, 

 darker in front, with a long pointed orange frontal triangle extend- 

 ing § the distance to the forehead, and including in it a small 

 ocellar triangle [only an ocellar triangle]; the front half of the 

 frons is covered with tiny bristles [bristles few and scattered]; 

 hind eye margins broad, two orbital bristles with tiny ones between 

 [three orbitals on grey borders], divergent ocellars inserted on 

 lines joining the ocelli, parallel inner verticals, divergent outer, and 

 post-verticals just behind the line formed by the bases of the 

 vertical pairs. 



Front view : — the frons runs on into the cheeks, both being 

 demarcated from the face by the lunule and by side furrows extend- 

 ing to the upper mouth margins ; the face is orange, covered with 

 silvery hairs and contracted below [broader in buccata]; the grey 

 upper lip projects ; palpi very stout, orange and covered with dark 

 hairs [less hairy], the ridged yellow tongue is well visible. The 

 arched side furrows of the face form two well-marked shallow 

 antennal foveae ; the antennae are separated at the base by a nose 

 projecting below the lunula : they are all orange, 1st joint some- 

 what orbicular, with tiny black bristles; 2nd joint calyciform, 

 bristled, especially below inside, 3rd joint flattened orbicular, 

 darker, but covered with silvery pollen; arista practically bare, 

 a little longer than whole antennal length, awn-like, the basal 

 joints stout, the second coneing into the flagellum. 



Side view : — profile rather like buccata, but while the latter has 

 a median nose, broad and slightly convex in profile, the present 

 species has a distinctly concave profile, and hence the forehead 

 appears more prominent. Eyes bare, rather oval, the long axis 

 sloping from vertex to cheek, with the sharpest curvature at the 

 upper end of this axis [eyes much more nearly round] ; jowl as deep
