PERILAMPUS CAPITATUS, new species 



Female. — Length about 2-3 mm. Head: Frons without a carina, 

 meeting vertex in a sharp angle (very rarely not very sharp); emar- 

 gination of fronto vertex markedly obtuse; ocellocular area and frons 

 between eye and scrobal cavity smooth except for hair punctures; 

 malar furrow more than half the width of cheek at apex (in males 

 sometimes no more than half the width); ciypeus wider than long 

 and more or less longer than hyperclypeal area; cheeks convexly 

 rounded and smooth; head in front view, with very rare exceptions, 

 distinctly transverse; eyes about reaching level of base of ciypeus. 



Thorax: Area along inner margins of parapsides smooth; umbili- 

 cate punctures on mesoscutum and scutellum large and angulated, 

 the interspaces usually thin, sometimes slightly thickened along 

 median line of thorax; scutellum more or less distinctly broadened 

 apically; pronotum laterally as long as or not much shorter than 

 dorsal margin of prepectus, the carinate margins of prepectus not 

 converging ventrally to form a single carina; axilla with a triangu- 

 lar or roughly triangular extension on side of scutellum, this exten- 

 sion as wide as or wider than long with its base extending above 

 middle of axilla, the face of axilla sloping toward base of extension 

 and not depressed or excavated above base of extension; basal 

 shallow furrows on underside of apex of scutellum usually not turn- 

 ing caudad medially but meeting to form a single curved furrow, 

 occasionally meeting in a slight angle ; postmarginal vein about three- 

 fourths or more than three-fourths the length of the marginal vein. 



Abdomen: Posterior face broader than long to longer than broad 

 (sometimes very distinctly longer than broad in the males); first 

 tergite strongly transverse, smooth or weakly sculptured, its anterior 

 margin more or less distinctly elevated and truncate or sHghtly con- 

 vex, sometimes completely masldng posterior aspect of neck of pro- 

 podeum; third segment (second of the gaster) not at all or only slightly 

 exposed.
