as the eyes; scape dull, not stout, the margins not produced; pedicellum about 

 one-half as long as the first joint of the flagellum, the first joint of the flagellum 

 nearly as long as the second plus one-half of the third. AntenctB broken. Thorax 

 polished; parapsidal grooves of mesonotum not sharply impressed, metatho rax 

 rather granular, the pleura with a sinuate groove extending from a pit near the 

 anterior margin to the posterior margin ; wings fuscous, but not deeply ; neura- 

 tion typical as in the preceding species. Abdomen polished; first segment ele- 

 vated in the middle with two longitudinal grooves to each side, all rugose except 

 the exterior groove which is smooth; second abdominal segment with a small 

 equilateral triangular smooth space at the base extending posteriorly as a raised 

 line nearly to the posterior border, an oblique groove diverging to each side from 

 the lateral angles of the triangular space to a point near an oblique line that 

 represents the suture between the second and third abdominal segments; third 

 segment with the usual basal crenulated grooves which bifurcates laterally as in 

 perepicus; the third, fourth and fifth abdominal segments are smooth and 

 polished excepting the lateral portion which is rugulose ; ovipositor about as long 

 as the last three segments of the abdomen. Black; abdomen red; ovipositor 

 brown, the sheaths black. Sericeous as in perepicus.

Iphiaulax melanogaster, n. ep. 



Female. — Length, 7 mm. As in militis, differs as follows: Clypeus and 

 clypeal region with rugte, this may be an aberration; antenna3 fifty-two jointed 

 or nearly; first abdominal segment with longitudinal groove in the middle of the 

 median raised portion ; the second segment with a basal flat lunule from the 

 middle of which extends a raised line nearly to the posterior border of the seg- 

 ment, the segment is more coarsely sculptured, rather reticulate; the third and 

 fourth segments are smooth, rugulose laterally; the fifth segment entirely rugu- 

 lose; the ovipositor as long as the last four segments of the abdomen. Black; 

 abdomen brownish, ovipositor brown, the sheaths black.

Opius basiniger, n. sp. 



Second subdiscoidal (Sell open ; should, perhaps, form a new genus allied to 

 Nosopoea, from which it differs in having the stigma triangular. Related to O. 

 brunneiventris, of which it may prove to be the female. 



Female, — Length, 3.5 mm. Head shining; cheeks apparently impunctate, 

 polished; vertex and occiput smooth polished; face not distinctly polished, 

 rather closely punctured, broad supraclypeal cuneiform polished convex space 

 in the middle of the face, extending up to near the antennal line (an imaginary 

 line across the face and joining the lower edges of the antennal sockets) ; clypeus 

 shining, sparsely punctured ; mandibles shining, crossing at tips ; antennte thirty- 

 two jointed, the scape nearly as long as the first joint of the flagellum. Thorax 

 polished ; parapsidal grooves very abbreviated, represented only at the anterior 

 margin of the mesonotum by linear pits, a median dimple on the posterior fourth 

 of the mesonotum; scutellum elevated, polished, smooth ;. mesopleura with a 

 shallow, rather broad impression ; metathorax rather coarsely rugose, the meta- 

 pleura shining and somewhat roughened ; wings clear, tinted with brown, stigma 

 and costal nervure brown, the other nervures blackish testaceous, petiole of the 

 first discoidal cell as long as the first abcissa of the subdiscoidal nervure, petiole 

 of second submarginal cell nearly as long as the second transverse cubitus, second
