AMERICAN HYMENOPTERA. 437 



21. Callicryptus pulehrifasciatus sp. n. 



Ferruginous-rufous, the flagellum of antennae black with joints five 

 to ten and the apex of the fourth yellowish-white, the four hinder tibiae, 

 tarsi and the apex of the four hinder femora narrowly black ; wings 

 dark fuscous, a yellowish-fulvous cloud extending from the base of the 

 transverse basal and near the base of the transverse median nervures 

 to the commencement of the radial nervure and a smaller one, pyri- 

 form in shape, with the apex distinctly narrowed to a bluntly rounded 

 point, extending from the costa, across almost the middle of the radial 

 cellule, but nearer its apex than its base, to the cubitus, touching the 

 outside of the areolet, the contracted part beginning at the middle of 

 the latter ; there is a broad, similarly colored band across the middle 

 of the hind wings. Palpi and apex of mandibles black. 9 . Length 

 13 mm., terebra 8 mm. 



Malar space one-third of the length of the eyes. Face, front and 

 vertex shagreened. Mesonotum finely and weakly punctured, the 

 pleurae more strongly punctured, the centre of the propleuras irregularly 

 striated, more strongly at the base than at the apex. Parapsidal fur- 

 rows weakly indicated at the base only. Metanotum weakly shagreened, 

 the basal transverse keel narrow but distinct ; the second is interrupted 

 in the middle and is stronger on the outerside. The abdominal petiole 

 has the basal half on the sides somewhat strongly, vertically striated. 

 The parastigma and stigma are colored like the cloud ; the areolet is 

 large, 5-angled, slightly narrowed in front, and receives the recurrent 

 nervure shortly beyond the middle ; the discocubital nervure is un- 

 broken and the transverse median nervure interstitial. 



The cf is similarly colored. The amount of black on the 

 legs seems to vary.

Mesostenini. 

 ATELEONOTUS gen. nov. 

 Parapsidal furrows absent. Metanotum broadly rounded 

 behind, closely reticulated, with neither transverse keels nor 

 spines, the spiracles linear. Areolet distinct, longer along 

 the transverse cubital nervures than along the radus, the 

 second transverse cubital nervure more distinct than usual ; 

 the recurrent nervure received in its apex. Transverse median 

 nervure received very shortly beyond the transverse basal ; 

 the discocubital nervure is unbroken. Transverse median 

 nervure in hind wings broken near the bottom. Wings vio- 

 laceous, with a hyaline cloud near the apex. Clypeus sepa-
