Otlyiierus simpliripes sp. nov. 



Black; a large squarish mark on the upper half of the clypeus, with the sides 

 and apex rounded, a small mark on the top of the vertex close to the eyes, a line 

 on the pronotum, dilated in front, a small round mark below the tegulae, dilated 

 downwards at the base, the hinder third of the tegulae, a large crescent-shaped 

 mark on the hinder half of the scutellum (the rounded end at the apex), the 

 apices of the abdominal segments, the lines dilated laterally, the 1st line dis- 

 tinctly so, yellow; the tibiae and tarsi yellow, the former black behind. Wings 

 hyaline, the nervures black. % . Length 7 mm. 



Form short and broad, the thorax oval, rounded before and behind, the sides 

 of the median segmeut rounded, not angled. Head wider than the thorax, the 

 temples roundly narrowed. Clypeus longer than wide, its apex ending in two 

 triangular teeth, which are longer than they are wide at the base. Antennae 

 with the apical half distinctly thickened, flattened below, without a hook, and 

 apparently not curled. Hind ocelli separated from each other by a slightly 

 greater distance than they are from the eyes. Median segment short, a narrow 

 furrow down the middle, the sides broadly rounded, not projecting much. Head 

 and thorax closely punctured, the metapleurse closely striated, coarsely above, 

 finely, more closely below; both are covered closely with short silvery pubes- 

 cence. Legs slender, the middle femora not denticulate. Basal segment of ab- 

 domen cup shaped, short, not separated by a constriction from the second. First 

 recurrent nervure received shortly beyond, the 2nd shortly in front of the mid- 

 dle of the cellule; the radial cellule wide, short, rounded at the apex. Palpi 

 small. 



Hab. — Mexico. 



This little species comes closest to the subgeuus Epiponiis and to 

 the Division Antepiponus, Section 2 (cf. Saussure, Syn. of Amer. 

 Wasps, 3G0), but is not quite typical, e. g. the antennae can 

 hardly be said to be "curled up into a spiral at the extremity;" 

 and the femora are simple, not dentate as in the males of the typical 

 Epiponus.

Iplihin l:i \ iii;iiiiha-usis sp. nov. 



Black; the basal five segments of the abdomen red, the legs pale testaceous; 

 the mandibles rufous, black at the apex; palpi pale testaceous, wings hyaline, 

 slightly tinged with yellow; the nervures and stigma yellow; a blackish cloud 

 commences shortly behind the transverse basal nervure, wider in front than 

 behind, extending to the apex of the basal abscissa of the radius and not ex- 

 tending much beyond the base of the 1st cubital cellule; there is a similar but 

 larger cloud at the apex, commencing at the end of the stigma and shortly be- 

 yond the 2nd transverse cubital nervure; there is a wider cloud on the apex of 

 the hind wings. 9- Length 7; terebra 2 mm. 



Smooth and shining; the 2nd abdominal segment in the middle and the 3rd 

 punctured more distinctly all over; the furrows on sides of the 1st segment with 

 some clearly separated, not very stout keels. Area on 2nd segment narrowed to
