with dense rows of hairs. On the lower surface the 2nd vein 

 has a» dense row of very short black hairs, getting a little 

 longer towards the costa ; the 3rd vein is similarly, hairy, 

 but on the upper surface instead of the lower. 



The whole insect is orange, with black marks. 



Type, the following species. 



Cestoplectus intuens, sp. n. 



Head (top and front view, figs. 24 & 23) : — All dull orange, 

 with fine hairs ; ocellar spot black ; in front of it a tiny 

 shining area, which may represent the triangle ; a well- 

 marked ridge extends from eye to eye over tjie antennal 

 bases, and hence the front of frons is slightly hollowed ; 

 antennal pits with a narrow median keel between. Antenna 

 (fig. 25) with orange basal joints and deep black 3rd, the 

 pubescent arista also black. Face yellow, the broad inferior 

 eye-margins running up to the antenna?; mouth emarginate; 

 palpi rather club-shaped, black. Side-view (fig. 22) : jowls 

 and hind head yellow, the latter with two extremely fine 

 divergent dark lines from neck to vertex. 



Thorax : dorsum dullish orange, with pale hairs ; two 

 black bands run from the neck over the dorsum, but these 

 terminate some distance before the scutellum, diverging 

 slightly behind ; on each side is a largish black oval spot 

 just in front of the well-marked side portion of the cross 

 furrow; behind the furrow is a short black stripe in line with 

 the spot, and there is a similar stripe above the wing-base. 

 The calli are large, almost scale-like, smoother than the 

 dorsum, almost hairless, and brightish yellow. Scutellum 

 as in generic diagnosis, somewhat flattened discally, and there 

 blackened except for an orange median line; it is pale- 

 haired like the dorsum. Pleura shining orange, the margins 

 of the sclentes more or less black-bordered ; a large black 

 subrectangular spot over the mid coxa. 



Wings (fig. 26) clear, with brown veins, which bear hairs 

 as desciibed above. Halteres all orange. 



Legs long, especially the hind pair; all coxaa, trochanters, 

 and femora bright yellow ; front and hind tibiye more or. less 

 blackened except at extreme tips, middle tibia orange ; front 

 and hind tarsi infuscate on middle of all joints, mid tarsus 

 slightly so on 1st joint.
