40 PKOCBEDINGS OF THE NATIONAL MUSEUM vol. 76 



primary punctures moderately large; lower portion with a medial 

 extension of punctures of first-degree density; a broad preocellar 

 region having numerous interspaces broader than an ocellus; sec- 

 ondary punctures more numerous than primaries on lower two-fifths, 

 extending upward as far laterally as medially. Antennocular dis- 

 tance greater than width of antennal fossa. Clypeal extension with 

 its apical width about equal to the clypeoantennal distance; apex 

 shallowly emarginate and very narrowly impunctate, with a thick 

 edge. Pronotum with primary punctures of moderate size, largely 

 of third-degree density, a few secondary punctures in the median 

 anterior region; sides with coarse, anastomosing striations on the 

 anterior half, with a series of diagonal rugae tapering toward the 

 alar angle. Mesepisternum with primary punctures large, round, 

 deep, clearly outlined, and separated by distances greater than their 

 diameters, the interspaces with well differentiated secondaiies 

 which, at the center, are not much more numerous than the primary 

 punctures. Scutellum with impunctate apex medially wider than 

 diameter of lowest primary punctures. Metanotum with punctures 

 much smaller than the largest primary punctures of the scutellum, 

 and of sparse third-degree density ; sometimes nearly impunctate or 

 with median patch of dense secondary punctures. Tegula with a 

 well-defined impressed line, continuous about the lateral and poste- 

 rior margins, sometimes interrupted at outer hind corner. Wings 

 with the radial cell not extending apically quite as far as second 

 cubital cell. Propodeum with the areola rather variable, about one 

 and one-half times as long as wide, lateral carinae on outside bor- 

 dered with vague grooves, median carina extending nearly to trans- 

 verse carina, enclosed area with definite transverse ridges ; side with 

 its lower region finely striate, without hairs; posterior aspect not 

 finely punctate but reticulo-rugose, particularly about the median 

 carina which is evident on the lowest three- fourths. First tergite 

 with preapical band not in a definite depression, composed of a single 

 roAv of punctures which is often curved toward the apex medially. 

 First sternite irregularly punctate on disk, with an apical crenulate 

 fossa ; lateral grooves on posterior half, frequently extending inward 

 anteriorly from the border of sternite. Tergites 3 to 5 not slia- 

 greened; with posterior punctures separated from margins at most 

 by four times the diameter of the largest adjacent primary punc- 

 tures; marginal linear groove complete, or outlined by interrupted 

 gouges over dorsum of last four segments; lateral denticle of fifth 

 sternite present as a longitudinal ridge arched over an orifice. 

 Length, 6 to 8 mm.
