310 PERCY SLADEN TRUST EXPEDITION 



8. Sapromyza funebricornis, ii. sp. 



Head (PI. 15, fig. 8). Frons dull brownish yellow, eye-margins and ocellar spot 

 somewhat shining. Face whitish yellow, jowls with scattered bristles, vertex bristly along 

 edge from centre round the eye-margins. Antennse with first two joints brownish, third 

 joint black; arista sub-plumose, black, the basal joint pale. 



Palpi pale, filiform, with a few long bristles on the lower side. 



Chsetotaxy normal, post-verticals crossed about half-way ; all the bristles stout. 



Thorax. Greyish yellow, uniformly covered with tiny bristles ; between the dorso- 

 central rows these form the achrostical bristles which are somewhat irregularly arranged in 

 six rows, the four middle rows being fairly regular and equidistant, the bordering rows 

 more irregular. 



Chsetotaxy normal with (l-f2) dorso-centrals, humeral, two post-humeral, one 

 presutural, two supra-alar, one intra-alar, two prescutellar. 



Scutellum the same colour as the thorax, broadly rounded at the tip. 



Wings (Fig. 4) slightly tinged with yellow ; veins yellow. 



Fig. 4. Sapromyza funebricornis, n. sp., wing. Fig. 5. Sapromyza mahensis, n. sp., wing. 



Halters yellow. 



Legs all yellow. Front femora with the usual two rows of bristles towards the end 

 on the posterior side, both upper and lower rows have about three bristles ; the interior 

 lower side (where it would be clasped by the tibia if the leg were closed) has a distinct 

 row of tiny bristles on the tip third. Middle femora with a stout row of some five bristles 

 on the distal end of the anterior side, tibiae with a crown of spines. Hind femora evidently 

 ciliated beneath, the ciliation beginning at the middle and getting longer towards the tip. 

 The bristly hairs so commonly present on the ventral parts of the middle and front sterno- 

 pleuree and on the coxae are very well developed. 



Abdomen. The same colour as the thorax ; margins with stout bristles which 

 extend over to the margin of the succeeding segment. The surface has scattered hairs. 

 The segments diminish slightly in size from the second to the last. 



In the male there is a slightly swollen hypopygium, but none of the specimens 

 possessed the appendages referred to in the next species. 



Size, excluding antennae, 3|- mm. 



Localities. Seychelles. Silhouette : low coconut-planted country near the coast, 

 Pointe Etienne, 17. IX. 1908; Mare aux Cochons plateau, one specimen, IX. 1908.
