covered with large shallow, more or lees separated punctures; pro- and meso- 

 pleura shining, smooth, rather closely punctured, the upper fourth of the meso- 

 pleura rugose; metathorax very coarsely reticulate, the pits more or less, nearly 

 a millimeter in width; three nearly semicircular ridges on the apical third of the 

 metanotum; wings strongly brown, nervures and stigma dark brown; recurrent 

 nervure received a little beyond the transverse cubitus, almost interstitial; 

 the apical side of the third discoidal cell a little more than twice the width 

 of the basal side of the cell ; transverse median nervure in posterior wings broken 

 in the middle. Abdomen smooth, petiole polished, succeeding segments dullish, 

 minutely, sparsely punctured. Brownish ferruginous; face and lower half of 

 cheeks largely yellow ; a spot between the ocelli, sternum, basal margin of meta- 

 thorax, posterior coxa? and basal trochanter of posterior legs and apical third of 

 posterior tibia; black or very nearly black; dorsum of second, ultimate and pe- 

 nultimate abdominal segments more or less black; dorsal edge of prothorax and 

 a small spot on anterior edge of dorsulum blackish ; exserted portion of oviposi- 

 tor brown, translucent, as long as the dorsal aspect of the third segment of the 

 abdomen.

Atrometus angitioides, n. sp. 



Female. — Length, 9 mm. Head dullish; cheeks apparently impunctate; 

 face with small separated punctures; antenna' about forty-two jointed, scape and 

 pedicellum together shorter than the first joint of the flagellum. Thorax largely 

 dullish; the parapsidal grooves represented only by very shallow channels on the 

 anterior half of the dorsulum; the dorsulum punctured nearly like the face; 

 mesopleura more shining than any other portion of the insect, with a rather 

 broad oblique groove that is transversely striate, separating a triangular polished, 

 almost impunctate area from the lower anterior portion of the sclerite; scutellum 

 more sparsely punctured than the dorsulum; metanotum divided into areas by 

 strong, raised lines or ridges, basal area nearly quadrate, areola confluent with 

 the petiolarea, forming a long, nearly parallel-sided enclosure, the areola, if com- 

 pleted, would be pentagonal and about one and a half times as long as broad, 

 the lateral angles far above the middle, areola smooth and shining, minutely 

 sculptured, the petiolarea transversely striate, the striie not very distinct; 

 metapleura rather closely, distinctly punctured, the tegument between minutely 

 sculptured; wings with a brownish tinge, nearly clear, stigma pale yellowish, 

 nervures dark brown; nearly all of the apical abcissa of the radius and the 

 apical abcissa of the cubitus very pale testaceous: first abcissa of the radius 

 about two-thirds the length of the second abcissa; transverse cubital nervure a 

 little less than one-half of the basal abcissa of the radius; recurrent nervure 

 nearly twice the length of the transverse cubitus, the abcissa between the two 

 very short, the recurrent nervure almost interstitial; the stump of a distinct 

 nervure beyond the recurrent nervure is about one-half the length of the trans- 

 verse cubitus; transverse median nervure interstitial; the second abcissa of the 

 discoidal nervure a little shorter than the transverse cubitus, the disco-cubital 

 nervure nearly straight, not broken or bent. Abdomen smooth ; petiole polished, 

 succeeding segments subtle, rather sparsely, minutely punctured, the second 

 abdominal segment finely, longitudinally striate. Covered with short, fine, 

 whitish pubescence, nowhere conspicuous. Ferruginous; an orbital line, scape, 

 clypeus, mandibles, coxa? of four anterior legs and second ventral abdominal seg- 

 ment more or less yellowish; large part of occiput, vertex, front, flagellum, base 

 of metanotum, base of petiole, basal half of second abdominal segment, base of
