Black ; the flagellum more or less on the under side, the femora, 

 tibiae, and anterior tarsi, red. Head and thorax opaque; abdomen 

 shining, very finely punctured ; head and thorax (except a shining space 

 on the mesopleurse) covered with a close pale pubescence, a sparse 

 hair fringe on the base of the second segment, the rest of the abdomen 

 glabrous. Antennee scarcely so long as the body, microscopically pilose, 

 the joints cylindrical, the last much longer than the preceding. Head 

 a little broader than the thorax, the pile on vertex very short, longish on 

 the face ; palpi testaceous. Thorax with the parapsidal furrows distinct 

 throughout ; the hair is longest on the scutellum and median segment. 

 Petiole shining, projecting a little above the neck of the median seg- 

 ment, which is rugose ; the second segment as long as the third ; the 

 apical united, and shorter than either ; they bear minute scattered punc- 

 tures, and are beneath more or less testaceous. Legs stout, pilose, the 

 coxae bearing long white hair ; the hind tarsi not much longer than the 

 tibiae, fuscous or blackish. Wings hyaline, sub-hyaline, or slightly 

 smoky ; the nervures testaceous at the base of the wing, fuscous on the 

 rest ; the spurious nervures distinct ; the areolet complete, obliquely 

 triangular ; the cubitus reaches to the end of the wing. 



The $ similar, but with the antennae a little longer, their third joint 

 deeply excavated and shorter a little in proportion to the fourth, the 

 last joint being also a little shorter. 



Length 3 4| m.m. 



The flagellum in both sexes may be only reddish at 

 the base, or more or less throughout on the under 

 side ; the femora are sometimes marked with black, 

 and in some specimens the legs have a yellower hue 

 than others, and the tarsi may be almost black.
