1. EUCOMYS HIBISCI new species. 
Female :—Length, 1.33 mm. 
Deep orange yellow, the abdomen dark metallic purple; legs and scape paler yellow; 
rest of antenna concolorous or nearly. Pronotum and vertex washed with purple. Fore wing 
embrowned to apex from a little out from base but clear disto-caudad, in a transverse, slit-like 
spot just distad of postmarginal vein, in a distinct not very narrow transverse band from the 
distal fourth or less of submarginal vein and along the caudal margin proximad of this 
cross-band. A clump of coarse black sete at the proximal margin of the cross-band of fore 
wing, cephalic half, followed proximad by over a half dozen lines of normal discal cilia. Post- 
marginal and stigmal veins rather long, subequal, the stigmal curved, the marginal distinctly 
shorter, about twice longer than wide, not half the length of the stigmal vein. Oblique hairless 
line obscure, of necessity short because of the hyaline, naked cross-band. Head lenticular, the 
scrobes short, the surface finely transversely sheened, the frons and vertex with thimble 
punctures; lateral ocellus over their own diameter from the eyes. Scutum very finely longi- 
tudinally lined, hispid. Axille meeting. Apical tuft of hairs on scutellum black. Hind legs 
more or less black. Flagellum clavate, compressed distad, the club short, truncate; scape 
slender, purple at tip above; pedicel rather long, a little longer than funicle 1, which is subequal
