Overview
Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141.


FEMALE—Length 7-8 mm.; black, with basal segment of abdomen bright ferruginous; antennae blackish above, reddish beneath; face marks yellow, triangular, entirely filling area between clypeus, eyes and antennae, terminated acutely above antennae, tip slightly divergent from eye margin; collar with large yellow maculae, and tubercles yellow; tegulae dark brown, sometimes maculated; wings hyaline at base, becoming infuscated apically, veins and stigma fuscous; femora blackish or fuscous; front tibiae yellowish at base, otherwise ferruginous, basal third of mid tibiae and basal half of hind tibiae yellowish, apically dull ferruginous; all tarsi ferruginous; face narrowed below; cheeks about as broad as eyes in lateral view; foveae deep, distinct, linear, separated from eye by about an equal space, slightly divergent from eye above; 2nd and 3rd segments of flagellum slightly broader than long, others about as long as broad; front coxae simple; dorsal area of propodeum about as long as metanotum, very coarsely reticulate, posterior surface coarsely reticulate, bordered by a low carina, but divided by a deep median longitudinal groove which is broadened above, lateral faces finely rugose; metanotum densely rugose; face below antennae tessellate, with sparse, shallow, obscure punctures, deeply and closely punctate above antennae, subrugose; punctures of scutum and scutellum deep, distinct, rather close and quite coarse; pleural punctures very coarse but rather shallow, close but not contiguous, interspaces tessellate; basal segment of abdomen shining, impunctate, following segments also to some degree shining, but with very minute and rather close punctures.

MALE—Length 6-7 mm.; black, with basal segment of abdomen bright ferruginous; antennae fuscous above, ferruginous beneath, scape black; mandibles yellowish in part; labrum black; tegulae entirely fuscous; wings hyaline at base, becoming infuscated apically, veins and stigma fuscous; maculations yellow, as follows: entire face below antennae, supraclypeal mark triangular above, face marks extending along eye margin above antennae and truncate or rounded apically, conspicuous transverse maculae on collar, tubercles, all tibiae and tarsi except that front and mid tibiae have a reddish blotch beneath, and all spurs yellow; face narrowed below; cheeks narrower than eyes; scape rather robust, diameter at apex about one and a half times that of flagellum, basal segment of flagellum slightly shorter than broad, these dimensions sub- equal on 2nd segment, 3rd and following segments considerably longer; front coxae simple; dorsal area of propodeum sloping, about as long as metanotum, very coarsely reticulate, substriate, propodeum otherwise quite coarsely reticulate, posterior face bordered by a quite distinct carina, this interrupted above by a central pit or excavation; metanotum coarsely rugose; scutum coarsely and very closely punctate, punctures well separated on scutellum, pleura very coarsely rugose; basal segment of abdomen shining, practically impunctate, 2nd and following segments with minute and rather close punctures; wings of 7th sternum sub- triangular, outer, slightly concave margin fringed with fine setae, apical angle attenuated, slender and elongate; distal pedicel of 8th sternum quite narrow, the truncate tip slightly incurved; penis valves of genital armature quite slender, much shorter than gonostyli, these rather robust, narrowly rounded apically.

DISTRIBUTION—Florida to the coastal plain region of North Carolina, the westernmost record being Raleigh. The period of flight is from May, in Florida to early September in North Carolina.

FLOWER RECORDS — Cephalanthus, Hypericum, Melitotus and Parthenocissus. Metz wrongly associated the two specimens described as Prosopis fossata. The male was made the type, and that proves to be a synonym of P. schwarzi Cockerell. The female is that of ornatus, and as fossata cannot be used, this later name is valid.

Identification
H. ornatus is very similar to H. nelumbonis. Generally, H. nelumbonis has a black pronotal collar while H. ornatus has yellow maculations on the pronotal collar. However, rarely, H. nelumbonis is maculated on the collar. Other differences include the color of the hind tibia. In both there is yellow basally. H. nelumbonis, however, is very dark apically, while H. ornatus is an orangey red. The pits on the scutellum are generally more widely spaced in H. ornatus. Also, the relative heights of the flagellar segments is generally different. In H. nelumbonis the F2 is just more than half as long as F1, while in H. ornatus, F2 is nearly as long as F1. Of all of these characters, however, the color of the hind tibiae appears to be the more dependable.
