black hairs as in grandis; third joint a little wider than the second, 

 nearly twice as long as fourth, and fully as long as fifth, which is a 

 little longer than in grandis; fifth joint oval with a few white hairs 

 at tip, but they are not conspicuous as in grandis; fourth and fifth 

 joints black, the fourth longer than wide. 



Female. — Is almost like that of grandis; still the third vein is a 

 little straighter and therefore more parallel with fourth; the bend in 

 fourth vein is a very little nearer the cross vein, and perhaps the face 

 is a little more white in color than that of grandis. 



Described from 3 males and 2 females taken in Monterey County,

i/aZe.— Length 4.3-5 mm.; of wing 4-4.5 mm. Face of moderate 

 width, a little wider above, silvery white. Front shining green, 

 usually with blue or violet reflections. Antennae (fig. 212a) yellow; 

 third joint about one and one-half times as long as wide, nearly 

 straight above, rounded below, pointed at tip. Lateral and inferior 

 orbital cilia white, about four of the upper cilia on each side black. 



Thorax green with slight bronze, and usually with conspicuous 

 blue reflections; dorsum dulled with a little grayish pollen; pleurae 

 with white pollen. Abdomen green with bronze reflections; the 

 white pollen on its sides abundant. Hypopygium black, more or 

 less yellowish on upper side; its lamellae of moderate size, somewhat 

 orbicular, white with a narrow black border on the apical margin, 

 jagged and bristly at lower corner, fringed above with little black 

 hairs. 



Coxae, femora, and tibiae yellow, almost whitish; middle coxae 

 with a blackish streak on outer surface; fore coxae with white pollen 

 and very minute white hairs on the anterior side, these hairs so small 

 that the surface appears almost glabrous. Middle and hind femora 

 each with one preapical bristle, the latter with very minute white hairs 

 on the lower half, and ciliated on lower inner edge with long, delicate 

 white hairs, the longest of which are slightly longer than the width 

 of the femora. Middle tibiae with one bristle on lower anterior edge 

 near basal third, their basitarsi without a bristle above. Posterior 

 tibiae only shghtly thickened; the usual glabrous stripe on upper 

 surface narrow and reaching from near the base to apical third ; there 

 is also a glabrous streak on inner surface from the base to near their 

 middle. Fore tarsi (fig. 2126) nearly one and three-fourths times 

 as long as their tibiae; first four joints pale yellow, fifth black, com- 

 pressed, nearly orbicular, stifl a little wider at tip; second joint throe-
