FEMALE—Length 7 mm.; head and thorax green, abdomen piceous, maculae bright yellow; face considerably longer than distance between eyes; eyes subparallel; cheeks sub- equal to eyes in width; vertex very narrow, lateral ocelli located practically on its hind margin; foveae narrow and elongate, somewhat broader at lower end; mandibles bright yellow, becoming ferruginous at tip; labrum piceous; clypeus protruding fully two-thirds below suborbital line, largely piceous, but with a fine, median, interrupted, yellow line and small inconspicuous maculae at extreme sides; facial maculae small, not extending much above upper margin of clypeus; scape brownish, becoming somewhat yellowish at base; punctures of face below antennae sparse and fine but distinct, surface above antennae less shining, punctures somewhat closer but rather shallow, those on cheeks above minute and quite sparse, becoming somewhat more distinct below; pubescence of head and thorax erect, rather thin, entirely white; thorax entirely green, without maculae; tegulae yellowish-hyaline; wings whitish-hyaline, veins and stigma pale yellow, 1st intercubitus more or less forked to form a small intercalary cell, but this sometimes lacking; legs dark, the front tibiae yellow anteriorly, and all tarsi yellow; scutum and scutellum shining, punctures fine and distinct, quite sparse on scutum posteriorly but becoming somewhat closer otherwise; pleura less shining, punctures somewhat closer but rather shallow; terga 2-4 with conspicuous, bright yellow, transverse, basal maculae, these slightly interrupted at mid line; the more basal terga impunctate, punctures on the more apical terga becoming more distinct although fine.

MALE—Length 7 mm.; head and thorax green, abdomen piceous, maculae bright yellow; face slightly longer than distance between eyes; eyes subparallel; cheeks slightly broader than eyes; vertex very narrow, ocelli located practically on its hind margin; foveae small and shallow, located near top of eyes; mandibles bright yellow, becoming ferruginous at tip; labrum and clypeus entirely bright yellow; facial maculae large and conspicuous, filling area between clypeus and margin of eye, terminating acutely on eye margin at level of antennae; sub antennal areas and lower margin of supraclypeal area yellow; scape entirely yellow, flagellum testaceous beneath, more brownish above; punctures of face below antennae very sparse and fine, area above antennae rather dull, punctures closer but much more obscure, those on cheeks above very fine and sparse, becoming more close, coarse and deep below; pubescence of head and thorax very fine, erect and thin, entirely white; thorax green except for small yellow maculations on pronotal tubercles; tegulae yellowishhyaline; wings whitish-hyaline, veins and stigma pale yellowish or testaceous, stigma margined with dark brown; legs largely yellow, but hind coxae dark on outer surface, mid and hind femora with dark posterior blotches, and hind tibiae dark posteriorly, otherwise bright yellow; scutum and scutellum polished, very finely but distinctly punctate, punctures sparse on scutum posteriorly but becoming rather close otherwise; pleura less shining, punctures rather shallow but somewhat closer; abdominal terga 2-4 with basal, transverse, bright yellow maculae which are slightly interrupted at mid line; basal terga with very minute punctures, these becoming somewhat more distinct but still rather sparse on the more apical segments; apical margin of sternum 6 slightly incurved; sternum 7 with a very broad and deep emargination, the central part being practically linear in form; sternum 8 rather broad apically, with a rounded and rather deep emargination; gonocoxites bulbous, rounded apically, gonostyli compressed, tips narrowly rounded, more or less recurved, considerably shorter than the slender, elongate penis valves, volsellae much shorter than gonostyli, separated into a somewhat compressed cuspis and slender, elongate digitus.

DISTRIBUTION—North Carolina to Texas, in May.

FLOWER RECORDS — Batodendron, Diospyros and Stillingia.


Identification
Extracted from: Timberlake P.H., (1958). A Revisional Study of The Bees of the Genus Perdita F. Smith, with Special Reference to the Fauna of the Pacific Coast (Hymenoptera, Apoidea) Part III. University of Caifornia Press Berkeley and Los Angeles 1958, Volume 14, No. 5, pp. 303-410, plates 4-15.

The specimens from Highlands Hammock State Park may represent a new subspecies when supported by more material. The female has the clypeus yellow except for two submedian stripes on the disk and the yellow bands on tergites 2 to 5 broad and entire, but the male is about normal for the species.
