are seen correspouding to the antennse. Eyes thickly pilose, con- 

 tiguous for a k)ug distance ; vertical triangle small, black. Thorax 

 with short, black pile, in color brilliant green, above in front with dis- 

 tinct bronze or violet reflections. Second segment of the abdomen on 

 each side with a large, less shining, and more purplish, but not con- 

 spicuous spot; pile of abdomen short, black, on the fourth and fifth seg- 

 ments longer, yellow. Venter, pectus, and cheeks very brilliant bright 

 green. Legs black, the femora slightly shining green ; tarsi more 

 brownish or reddish black, the hind metatarsi thickened, and as long 

 as the remaining joints together. Wiugs nearly hyaline, faintly brown- 

 ish toward the base; a small but very distinct brown spot reaches from 

 the costa to the fourth vein over the cross- vein, which is very near t(» 

 the base of the discal cell ; at the junction of the first and second veins 

 there is a minute brown spot ; the marginal cell at the tip juts strongly 

 into the submarginal cell. 



Five specimens from San Domingo and one from New Mexico (E. 

 Keen). The sj-nonymy of V. azurea Phillipi seems probable; the figure 

 does not, however, show the bend near the tip of the second vein.

 with the black of the cheeks, the latter with a narrow yellow stripe. 

 Front in female yellow, with broad black stripe from the ocelli to the 

 antennae ; the pile is fuscous, black at the vertex. Antennae brownish-

 broader throughout, with the basal portion distinctly convex above; 

 arista a little longer than the joint, loosely plumose. Eyes in both 

 sexes thickly black pilose. Dorsum of thorax black shining in its middle, 

 with blackit^h and yellowish pile; on the sides, extending from the 

 humeri to the posterior angles, with a broad yellow stripe containing an 

 oval black spot in its middle; in front of the scutellum there are two 

 small, rounded, yellow spots ; pleurae with two yellow spots, the larger 

 with a bush of whitish pile on the upjjer half, the other, smaller, spot
