wide as diameter of the apical primary punctures. Metanotum 

 densely punctate, with primary' punctures nearly as large as those 

 of the scutelhim. Tegula with only a vague, shallow impression on 

 the anterior lateral margin. Wings with radial cell equalling second 

 cubital cell in apical extension. Propodeum with its areola from 

 one and one-fourth to one and one-half times as long as wide, its 

 sides usually slightly convergent and concave, the median carina 

 wider than the lateral carinae, flattened on top, and usually ending 

 abruptly just before apex of areola, enclosed area irregularly and 

 transversely rugose and granulate; lower portion of sides densely 

 shagreened; posterior aspect granulate, the minute punctures poorly 

 outlined, the median carina developed on lower half or more. First 

 tergite with preapical band wide, its anterior margin somewhat 

 abruptly impressed, the punctures well differentiated only on the 

 posterior border. First sternite with apical fossa obsolete; disk 

 polished, impunctate; lateral grooves on posterior half, curved up- 

 ward anteriorly; a sharp median keel on anterior half. Tergites 3 

 to 5 usually shagreened; punctures deep, with clearly outlined mar- 

 gins; impunctate margins absent, or at most only as wide as the 

 diameters of the largest adjacent primary punctures; denticle on 

 fifth sternite appressed, its elevated margin moderately long, cres- 

 cent-shaped, and nearly parallel to apex of sternite, frequently with 

 smaller denticles similarly located on the fourth and third sternites. 

 Genitalia, in ventral aspect, with the outer clasper abruptly con- 

 stricted near the middle, the apical portion very broad and vaguely 

 quadrangular; second genital segment with its apical hook roundly 

 and bluntly pointed; the inner hind margin with a pronounced 

 rounded angle; distal portion of aedeagus Avith its apical lobes 

 larger than the lateral processes; the proximal portion of the 

 aedeagus broader apically them at its base.
