Thorax black except for a divided band on the pronotum, a small patch on the posterior lobe, a trace on the mesoscutum, an emarginate band on the scutellum, the entire enclosure, a reversed J-shaped patch on the propodeum, two large angular patches on the meso- pleiu-on and two small spots on the metapleuron, three pairs of patches on the sternum and a small patch on the tegula, all of which. Figure 33. Mexico. E. pundifrons puncti- frons (Cameron), E. pundifrons cavagna- roi, new subspecies are yellow; tegulae normal in form; the enclosure closely pitted except along the basal margin, and with a light medial groove; meso- sternal tubercles absent; legs largely yellow but with dark fuscous areas on all coxae, trochanters, femora and on the mid and hind tibiae; wings light fulvous; 2nd submarginal cell not petiolate. Abdomen with yellow bands on terga 1 to 5 deeply emarginate and the lateral expansion of the bands of terga 3, 4, and 5 with dark patches; a yellow patch on terga 6 laterad of the pygidium; first four sterna largely yellow; fifth sternum with lateral yellow areas; pygidium with sides convex, apex rounded, and base converging. This unique female is structurally like the female of E. pundifrons Cameron except for the more extended yellow parts. In the nominate subspecies the yellow of the scutellum is separated into two lateral large spots, the enclosure is black except for two elongate
