184 BULLETIN OF WISCONSIN NATURAL HISTORY SOCIETY. VOL. 3, NO. 4. 
Scutellum and post-scutellum convex, shining, the latter with an 
oval fovea on each side, the foveae vertically striated. M eta- 
thorax short, abruptly declivous behind, finely reticulated. 
Abdomen short, oval, stout, polished and impunctured. Legs 
ferruginous, the anterior femora thickened as usual ; first tarsal 
joint not longer than the following three united ; chelae small. 
Wings hyaline, with two fuscous bands ; the first indistinct, cross- 
ing at the tips of the basal cells ; second broad, beginning at the 
stigma and fading out apically and posteriorly. Both basal cells 
distinct. Stigma pale, oval, marginal cell incomplete. 
One specimen labelled Texas. Type in the collection of the 
American Entomological Society. 
This species is readily recognizable by its reddish color. The 
broad abdomen gives it a very wasp-like appearance, its general 
habitus simulating that of a small pompilid. 
CHELOGYXUS ATRICEPS Brues. 
Bocchus atriceps, Brues, Can. Ent. XXXVI, 118. 
On re-examination of the type of this species together with a 
second specimen recently acquired from Wisconsin, I find that 
the maxillary palpi are five jointed so that the species falls more 
properly in this genus.
