species from Mexico. In the entirely red legs of the female 

 and oval propodeal spiracles it is close to Ephialtes punicipes 

 (Cresson) recorded from Mexico and Central America, but 

 differs according to the characters given punicipes by Morley 

 (Rev. Ichn. '3, 1914, j)p. 59, 63) in having no carinae on the 

 propodenm and no trace of areas, and in the male in having the 

 hind tibiae and tarsi black with a white annuliis on the basal 

 half of the tibiae. 



5 . — Shining black; the legs nearly morocco red (R-clgvvay), the front 

 coxae blackish at base, the front legs often with a somewhat yellowish 

 cast especially on the tibiae and tarsi, the hind tibiae slightly more 

 brownish although rarely distinctly so, the hind tarsi still more brownish 

 on the upper side, the last joint becoming fuscous at apex, all the claws 

 blackish at apex, the femoro-trochanter . articulation sometimes blackish; 

 palpi yellowish brown, becoming fuscous on the basal joints; antennae 

 brown, the flagellum shading into fuscous on the apical half, the scape 

 black; the line marking the upper limits of the clypeal impression often 

 more or less reddish brown especially at the sides ; tegulae fuscous, 

 becoming yellowish at base ; spicula of ovipositor dark castaneous, the 

 sheaths black ; wings somewhat fuliginous, the, veins and stigma mostly 

 fuscous or blackish, the latter yellowish at base and the costal vein more 

 or less yellowish on its basal half. 



Head transverse, no wider than the thorax ; the temples short, oblique ; 

 the eyes slightly emarginate internally ; the frons deeply excavated to 

 form the scrobes, with a slight median carina forking in front of the 

 ocelli ; face a little wider than long, convex, slightly protuberant median- 

 ly, with a slight indication of a median carina above ; cheeks long ; cly- 

 peus at apex truncate with a slight median emargination ; antennae slen- 

 der, perfectly filiform, the flagellum with 27 to 30 joints. Face and base 

 of clypeus finely, rather closely punctate; the cheeks, temples, vertex 

 and occiput comparatively impunctate, smooth and shining; the frons 

 very finely punctate, the scrobes sometimes transversely aciculate in large 

 specimens, but usually smooth in small specimens. Face with a moder- 

 ately long, rather abundant yellowish pubescence, which becomes longer 

 on the base of the clypeus and on the mandibles. 



Notauli absent ; the epicnemia bent forward on the pleura in a broad 

 curve but rather widely separated from the propleura at either end ; the 

 propodeum without areas, only the pleural carinae being present, the 

 spiracles rather small and oval. Propleura transversely aciculate except 

 above ; the mesoscutum and scutellum appearing impunctate under low 

 magnification, but actually with very minute, rather close punctures, 

 which become somewhat larger and very crowded on the anterior part 

 •of the scutum; mesopleura with a similar but somewhat more distinct 

 puncturation above, becoming coarser and much closer below and on
