Pezomachus testaceicoxus, n. sp. 



Male. — Length, 6 mm. Head dullish, minutely, densely sculptured, appar- 

 ently microscopically rugulose; ocelli as in P. alogus; the clypeus not conspicu- 

 ously separated from the face; malar space distinctly higher than the mandibles 

 are broad at base; antennae broken, scape and pedicellum together about three- 

 fourths the length of the first joint of the flagellum. Thorax almost uniformly 

 dull, minutely sculptured; parapsidal grooves distinctly impressed on the an- 

 terior half of the dorsulum; propleura shining, rugulose; mesopleura with the 

 greater part of the upper posterior fourth polished, a short transverse groove 

 which attains the posterior margin of the sclerite separates the polished area 

 from the area beneath; the cryptine groove distinct from the anterior margin of 

 the lateral edge of the mesosternum to near the posterior edge of the sclerite, 

 extending up somewhat on the lower portion of the mesopleura ; scutellum rather 

 shining compared to the mesonotum; metanotum shining, rugose, distinctly 

 areolated, the raised lines very distinct, basal area nearly quadrate, areola hex- 

 agonal, a little longer than wide, the basal side a little shorter than the apical 

 side, the lateral middle angles a little below thfe middle of the areola, the four 

 sides not mentioned of nearly equal length; petiolariea broad, occupying practi- 

 cally the entire posterior face of the segment; the metapleura minutely sculp- 

 tured, dull; wings faintly brownish, almost clear, stigma and nervures dark 

 brown, the basal angle of the stigma whitish ; the open areolet with the sides 

 nearly equal; the transverse median nervure a little beyond interstitial with the 

 basal nervure; the transverse median nervure in the posterior wings broken dis- 

 tinctly below the middle, a little below the junction of the basal third of the 

 nervure with the middle third. Abdomen dullish; the petiole nearly twice as 

 broad at apex as at base, longitudinally striate on the apical half, rather rugose 

 on the basal half, the basal half with a distinct raised line on each side, the 

 raised lines parallel and forming the inner boundary of a shallow groove ; the 

 second segment is longitudinally rugulosoetriate; the succeedicg segments are 

 apparently minutely, microscopically sculptured. The pubescence is whitish 

 and nowhere conspicuous. Black; scape, pedicellum, basal spot on mandibles 

 and margin of second abdominal segment brownish testaceous; legs almost en- 

 tirely testaceous, posterior legs with apex of femora, tibiae and tarsi almost en- 

 tirely fuscous; second abdominal segment entirely pale brownish testaceous, the 

 succeeding segments at apex concolorous with the second segment, otherwise 

 more or less fuscous with some brownish testaceous in the middle.

 Platylabus (Colocnema?) omniferrugineus, n. sp. 



Superficially like Pbaeogenes Itevigatus. 



Female. — Head quadrate; face dull and closely, almost rugulosely, punc- 

 tured ; the clypeus not at all separated, the anterior margin of the clypeus 

 smooth, impunctate, and shining, anterior margin of the clypeus straight; la- 

 brum polished, roughened on the anterior margin, which also has a few punctures ; 

 front rather flat, slightly elevated, rather shining, and with well-separated 

 punctures; distance between the posterior ocelli about as great as the distance 

 between a lateral ocellus and the nearest eye margin, the ocelli forming a low
