LOKSA (all in TMB). Distribution : Ceylon (Sri Lanka), India, Sumatra. New to New Guinea. Euxestus papuanus sp. n. (Figs. 11-12) Body oval piceous-brown to reddish brown, shiny; dorsal surface sparsely pubescent. — Head: clypeus transverse with anterior margin rounded, surface slightly convex, coarsely punctured, punctures 1-1.5 diameters apart; frontoclypeal suture present; frons and vertex evenly convex, punctured as clypeus, vertical punctures a little larger than frontal; eyes large, coarsely facetted, prominent; antenna 10-segmented with short, oval antennái club, latter as long as segments VIII-IX together (Fig. 11). — Pronotum transverse with anterior margin practically straight, not bordered; lateral margins arcuate, finely and entirely bordered; pronotal disk coarsely punctured, punctures as large as on vertex, separated by 1-2 diameters; pronotal base with parallel rows of punctures; posterior angles acute, somewhat prominent. Scutellum transverse, triangular, surface smooth. — Elytra nearly 1.3 times longer than their maximum combined width, which is near one third from bases; each elytron with 8 fully developed rows of punctures; elytral striae not grooved, punctures absent apically; intervals between striae irregulary, finely punctured, sometimes impunctate. — Ventral side: fore coxal cavities closed behind ; prosternai process strongly widened apically, deeply grooved medially, surface flat, impunctate; mesosternum transverse, impunctate; metasternum and ventrites punctured; median line and femoral lines absent. — Legs : tibia long, slender; tarsi 4-segmented with segment I lobed below. — Length 2.1 mm, width 1.1 mm. Holotype: New Guinea (NE) Wau, Mt. Kaindi, 900 m, 27 VIII 1968 (No. NG-W. R. 8), DR. I. LOKSA (TMB). — 18 paratypes, all from New Guinea: 1, with same data as holotype; 1 with same data but collected by DR. J. BALOGH; 5, Wau, 8 IX 1968, (No. NG-W. R. 19), DR. I. LOKSA; 7, Wau, 22-30 IX 1969, (No. NGW-R. 10), DR. J. BALOGH; 4, Huon-Golf, Sambang, 1899, BIRÓ. Paratypes deposited in TMB and in the author's collection. Notes — This species is very similar to E. javanus ARROW described from Java, in having a broadly-oval body and by densely punctured dorsal surface. It can be distinguished from E. javanus by its impunctate mesosternum (punctured in javanus Jand by the prosternai process grooved medially (raised in javanus). Reference SEN GUPTA, T. & CROWSON, R.
