margin; disk of the axillae and scutellum rather roughly but very 

 finely reticulate; furrowed sides of mesoscutum, the mesopleura, 

 metapleura, and propodeum smooth and polished; declivous parts 

 of axillae smooth but with delicate reticulations, the declivous sides 

 of scutellum similar but more lineolate, especially towards the apex; 

 propleura, prepectal plates, tegulae and abdomen finely reticulate, 

 rougher on the tegulae and coarser on the basal tergitc of abdomen ; 

 metanotum with several fine oblique carinae on each side. 



Vestiture. — Face with very fine whitish pubescence on the promi- 

 nence between the antennal sockets, the occipital margin of the sides 

 of head with a conspicuous fringe of rather short white hairs ; collar 

 of pronotum and disk of mesoscutum rather conspicuously, but not 

 densely, pubescent with short white recumbent hairs; a few^ similar 

 hairs on the disk of the scutellum, the apical fascicle dense and black ; 

 apex of the abdomen with a few black bristly hairs beneath and on 

 the lateral margins, most of these arising from the apical ventrites. 



Coloration. — General color of the head and thorax ochraceous 

 orange to tawny (Ridgway) or even darker in one specimen, the 

 fronto vertex about Front's brown or darker, the scutellum still 

 darker and with a dark greenish luster; facial prominence (in some 

 specimens) and the mesopleura with a purple luster; posterior wall of 

 the scrobes and the ventral orbits of the eyes with a pale-green 

 luster; polished sides of the mesoscutum and the metapleura metallic 

 green; declivous part of the axillae brilliant gold, purple-red or 

 greenish in different lights; disk of mesoscutum and axillae with a 

 rather weak, dark bronzy luster; abdomen bluish black, the luster 

 mostly greenish and not especially strong. Scape somewhat tawny 

 in ground color but with a strong metallic green luster which pro- 

 duces a bronzy effect, its ventral margin narrowly blackish; pedicel 

 metallic greenish ; the flagellum bluish black, with a distinct but not 

 brilliant metallic luster. Front and middle legs, except the tibiae and 

 middle coxae, as well as the hind coxae concolorous with the pleura or 

 somewhat browner ; front and middle tibiae, middle coxae, and most 

 of the hind legs fuscous to blackish, the hind femorra usually 

 browner; dorsal margin of the front tibiae with a bluish luster, 

 the same parts of the middle and hind legs with a greenish luster; 

 apical joint of the tarsi fuscous to blackish, the tarsi otherwise be- 

 ing brownish yellow, although the front pair in one specimen are 

 almost all infuscated and the hind pair have only the second and 

 third joints pale; spur of middle tibiae dark. Wings hyaline on 

 the basal third and then abruptly fuscous on the rest of the disk 

 although becoming slightly paler toward the apex, and with a 

 narrow curved subhyaline line parallel to the posterior margin pres-
