in part. Area almost quadrate, sharply defined in part. Meshes of reticulation 

 on inetathorax large, sharply defined. Wings— first submargiual cell little more 

 than twice as long as high, otherwise like sercus. Transverse median nervure 

 interstitial with basal nervure. 



Abdomen. — Punctures coarse and close together. Second segment dull, punc- 

 tures small, not far apart, in felt lines like sercu.i, subtle area broad at base, 

 pointed at apex. 



Color. — Pale castaneous, antennse and greater part of legs pale testaceous. 

 Spot between ocelli, a lateral streak on second abdominal dorsal and ventral seg- 

 ments and part of four posterior femora black or blackish. Stigma almost black, 

 nervures very pale testaceous. Pubescence nearly entirely white.

Length, %, 13 mm. — Head. — Punctures very distinct, contiguous and almost 

 contiguous on front, well separated beyond, median impression rather shallow. 

 Posterior ocelli with a distance between them which is twice as great as that be- 

 tween them and anterior ocellus, and a little greater than that between them 

 and nearest eye mai'gin. No malar spa(!e. Mandibles elbowed almost to a L, the 

 terminal portion very slender and narrow, emargination distinct, but not deep, 

 tooth au acute angle. 



Thorax. — Sculpture of prothorax closely rugose. Dorsulum with strong punc- 

 tures, nearly contiguous, grooves strong, starting on anterior third. Scutellum 

 punctured, punctures contiguous. Postscutellum indistinctly sculptured, rugu- 

 lose. Propleura closely rugose, almost punctured, apparently no smooth area. 

 Bulged portion of mesopleura distinct, covered with shallow punctures close 

 together, depression punctured. Only a remnant of an area at base of metano- 

 tum. Meshes of the reticulation on metathorax large, very sharply defined. 

 Wings — a very faint third transverse cubitus, otherwise like sercus. Transverse 

 median nervure interstitial with basal nervure. 



Abdomen.— Petiole much like in alamotiis. Punctures of second segment small 

 and separated, numerous; felt lines as usual, on ventral segment reduced almost 

 to a spot. Subtle area large, semicircular in outline. 



Color. — Dull castaneous. Antennae darkened, brownish, legs pale testaceous. 

 Stigma testaceous, nervures pale testaceous. Pubescence nearly white, felt line 

 dark.
