duced backward. Foredisc flat medially, with a small, relatively high, 

 median ridge on posterior half of disc; strongly inflated laterally in a 

 shape of an S with eight (4+4) dots on inner sides, deeply excavated 

 laterad of these inflations. Collar, and two (1 + 1) round dots laterad 

 of the median ridge, without incrustation; other parts of forelobe 

 heavily incrusted. Hind-disc with two (1 + 1), L-shaped, high, trans- 

 verse carinae medially, turned with their bases to each other, and 

 with four (2+2) short, obhque ridges laterally. Latter produced over 

 actual lateral border forming lateral teeth of the hindlobe. Hind-disc 

 without incrustation, except along carinae. 



Scutellum subtriangular, shorter than width at base (11:19), 

 rounded posteriorly. Disc flat, without incrustation except on the 

 two (1 + 1) lateral, high, hatchet-shaped ridges with their blades 

 sideways. 



Hemelytra reaching apical third of tergum VII. Corium very 

 short, outer border carinate, incrusted ; membrane transparent, finely 

 corrugate. 



Abdomen ovate, longer than width across segment IV (59:45). 

 Lateral borders slightly, evenly convex. Connexival segments II and 

 III fused, provided with two longitudinal ridges converging anteriorly. 

 Other connexival segments rather flat, heavily incrusted; their outer 

 borders slightly convex from II to IV, angularly produced on hind- 

 halves from V to VII. Tergum incrusted laterally, posteriorly on 

 tergum VII; outer margin of incrustation obHquely raised. Parater- 

 gites small, triangular, incrusted, reaching tip of segment IX. Latter 

 subtruncate posteriorly. Spiracles very small, from II to IV ventral 

 but progressively nearing margin; lateral and visible from above 

 from V to VIII. Venter incrusted only laterally. Sternum incrusted 

 along borders. Propleura incrusted. 



Legs relatively long, slender; femora fusiform; tibiae cyHndrical, 

 slender. Tarsi with aroha. 



Color. — ^Under incrustation and on free parts, yellow brown to 

 brown; incrustation ivory. 



Measurements. — Total length 4.44 mm.; width of pronotum 1.4 

 mm.; width of abdomen 2.36 mm. 



HoLOTYPE. — Female, Satipo, Peru, P. Paprzycki collector, Apr. 26, 

 1941 (USNM type 67585). 



Proxius peruvianus, new species, is related to P. palliatus Champion 

 and may be separated from the latter by the following: genae produced 

 beyond the tip of antennal segment I; absence of excavation on postoc- 

 ular lobes; median ridge of the pronotum reduced to a very short, thin 

 carina on the hindhalf of forelobe; different shape of carinae on the 

 hindlobe of pronotum and scutellum.
