Diagnosis. This subspecies can be recognized by the following unique combination of characters: the integument is black; the hind femora and tibiae are red; the propodeum and first metasomal tergum bears scale-like pubescence ( Figs 7F–G ), which are sometimes difficult to see or have partially be wore away; the postnotum is arcuately broadened on each side of the median line, then constricted again ( Fig. 8D ); and the Cu vein is distinctly deflected downward at the base forming a posterior pocket in the second medial cell.

Distribution. Costa Rica to California, Mississipi valley to Illinois and north to Long Island, New York ( Evans 1966), Cuba ( Genaro & Sánchez 1989), Bahamas (Elliot et al. 1979), and Dominican Republic.

Host. Several species of orb-weaving spiders of the family Araneidae ( Wasbauer & Powell 1962; Kurczewski & Kurczewski 1968; Kurczewski 1981).

Remarks. Females build nests in the soil. The egg is not attached to the spider but to the wall of the cell ( Evans 1950). There are numerous records of adults feeding on honeydew, galls, flowers, and extra floral nectaries of several plant species ( Wasbauer & Kimsey 1985). Genaro (1995) recorded E. conterminus posterus (Fox) for the Dominican Republic. This subspecies, however, is a synonym of E. conterminus cressoni .
