48 PROCEEDINGS OF THE NATIONAL MUSEUM vol.76 



plainly shagreened ; a medial groove usually well developed ; primary 

 punctures rather regularly distributed, increasing in density toward 

 region just above antennae where they are of first-degree density; 

 hairs directed conspicuously outward. Clypeus with the lateral mar- 

 gin decidedly convex; impunctate apex frequently red, limited by 

 irregularly grouped punctures which approach the apex medially, 

 causing the impunctate area to be much broader at the sides than at 

 the center. Mandibles usually without median gi'oove. Antenna 

 with the first joint angulate apico-ventrally ; third joint slightly 

 longer than the greatest width; flagellum slightly fulvous beneath. 

 Pronotum with its transverse carina usually complete but weakly 

 developed; primary punctures densely distributed, with a tendency 

 to concentrate medially and in a discal band; secondary punctures 

 widely distributed and occurring densely just back of the carina on 

 the sides of dorsum; punctate area conspicuously shagreened, its 

 median longitudinal extension slightly narrov»^er than that of the 

 impunctate portion. Side of pronotum unusually free from sculp- 

 turing, with the usual rugulae at the ventral corner sometimes en- 

 larged to shallow grooves at their upper extension; several distinct 

 punctures along the posterior dorsal border; the upper disk highly 

 polished. Scutum with its notauli and its antero-medial groove 

 usually continuous; conspicuously shagreened. Metanotum densely 

 bipunctate with a polished callosity. Legs with tibiae and tarsi 

 of first two pair bright red; major calcarium of hind tibia uni- 

 formly tapering; hind basitarsus with two pricklelike spines on out- 

 side near middle, none of the same kind at the apex. Tegulae thin, 

 semitransparent, reddish, polished. Wings nearly hyaline; hyaline 

 lines not present. Propodeal areola almost rectangular in outline, 

 twice as long as wide, carinae uniform and narrow, without conspic- 

 uous bordering grooves; median carina not quite complete. Lower 

 portion of sides of propodeum wavy-rugose, not well differentiated 

 from the rugose upper half where the ridges are weak and disappear 

 posteriorly. Posterior aspect of propodeum with clearly defined 

 punctures, median carina not raised but defined by parallel grooves 

 extending beyond lower half. First tergite usually with a small 

 patch of minute punctures on the anterior slope; preapical band 

 vaguely defined by very fine, widely separated punctures in a broad, 

 shallow depression. First sternite polished and without sculpturing, 

 lateral grooves lacking. Intermediate abdominal tergites with large 

 apical setigerous punctures extending medially into subdiscal region. 

 Pygidium sparsely punctate on upper three-fifths, area of interspaces 

 greatly exceeding that of punctures, no marked impunctate emargi- 

 nation; apex faintly wrinlded below lowest punctures; all conspicu- 

 ously shagreened. Length, 8.5-9 mm.
