Genus Proxius Stal 



Proxius Stal, 1873, Kongl. Svenska Vet.-Akad. Handl., vol. 11, p. 141. 



Proxius has had six species which Usinger and Matsuda (1959, 

 pp. 113-114) placed into three subgenera: two of these, Proxius 

 Stal sensu stricto, with a single species and Neoproxius Usinger and 

 Matsuda, with four species, are American; the third one, Nesoproxius 

 Usinger and Matsuda, with a single species, is Sumatran. One new 

 species, belonging to the subgenus Neoproxius , is described herewith.

Figures 10, 11 



Female. — Elongate ovate; partially incrustated with an ivory- 

 liked incrustation. 



Head longer than Avidth across eyes (20:16), as long as width across 

 postocular projections (20:20). Anterior process long, parallel- 

 sided, deeply cleft anteriorly; genae much longer than clypeus, 

 cylindrical and truncate anteriorly, surpassing the tip of antennal 

 segment I by one-fifth of their length. Antenniferous tubercles 

 dentiform, slender, parallel-sided, reaching a little beyond middle 

 of antennal segment I. Eyes small, semiglobose, moderately pro- 

 truding. Postocular parts of head produced mto large, partially 

 punctured, triangular processes reaching far beyond outer border 

 of eyes. Vertex with a punctured elliptical, flattened elevation 

 running from clypeus to hindborder of head; head produced back- 

 ward, forming a long "neck." Antennae, clypeus, and two (1 + 1) 

 ovate, glabrous spots laterad of the elevated portion of vertex, rostral 

 atrium, and rostrum, not mcrustated; all other parts of head covered 

 with thick, ivory-like, incrustations. Antennae long and slender, 

 one and a half times as long as length of the head (32:20). Pro- 

 portions of antennal segments 6:5:13.5:7.5. Rostrum short, reach- 

 ing hindborder of narrow, deep, and short rostral groove; latter 

 closed posteriorly. Rostral atrium closed. 



Pronotum subrectangular, shorter than width across humeri (20:35). 

 Forelobe almost as wide as hindlobe (32:35). CoUar small, convex, 

 foreborder straight. Anterior angles produced forward far beyond 

 collar as two (1 + 1) lobes, these rounded interiorly and sinuate 

 exteriorly. Anterolateral angles subrectangular; lateral borders of 

 forelobe slightly sinuate, provided with a row of short, erect bristles 

 projecting through incrustation. Interlobal notch deep and narrow. 

 Lateral borders of hindlobe short, convex, deeply notched medially. 

 Hindborder sUghtly convex medially, posterior angles angularly pro-
