second and third abdominal tergites, a smoother fourth tergite, and

ROGAS POLITICEPS, new species. 



Female. — Length S mm. Vertex, frons, and posterior orbits pol- 

 ished; impunctate: face transversely wrinkled; opening between 

 clypeus and mandibles large; malar space about equal to the width 

 of a mandible at base, possibly a little longer; ocellocular line not 

 quite twice the greatest diameter of an ocellus; eyes long oval, dis- 

 tinctly eraarginate; posterior orbits as broad as the transverse diam- 

 eter of the eyes and only slightly receding; antennae 62- jointed in 

 the type, the first flagellar joint about one and one-half times as 

 long as broad, the following joints subquadrate; mesoscutum smooth; 

 the parapsidal grooves distinctly impressed, foveolate, and terminat- 

 ing posteriorly in a striate area; scutellum smooth; mesopleura 

 mostly smooth, with a slightly rugulose area just beneath the ante- 

 rior wing; propodeum entirely rugose with a rather weak median 

 carina; radius of the forewing with its second abscissa not quite 

 twice as long as the first, but only slightly longer than the first inter- 

 cubitus, the second cubital cell subquadrate; nervulus nearly twice its 

 own length beyond the basal nervure; hind femora about two-thirds 

 the length of their tibiae, tarsal claws pectinate; abdomen about as 

 long as the head and thorax; first, second, and third tergites with 

 strong parallel striae, those of the second and third tergite continuous 

 across the suturiform articulation and terminating a little before 

 the apex of the third tergite ; first and second tergites with a distinct 

 median carina which does not extend on the third tergite; apex of 

 third tergite and all of the following tergites smooth; ovipositor 

 about equal to the fifth tergite in length, not extending beyond the 

 apex of abdomen. Eyes, ocelli, antennae, and ovipositor sheaths 

 black, posterior tibiae shading from testaceous at base to black or 

 blackish at apex, their tarsi black, median and anterior tibiae and 

 tarsi similar to the posterior but not quite so dark; body otherwise 

 dark reddish testaceous; wings blackish, becoming somewhat paler 

 toward the apex.
