scarcely as long as wide, pointed at tip. Lateral and inferior orbital 

 cilia yellowish white, about five of the upper cilia on each side black. 



Thorax green with coppery reflections, which form three vittae 

 on the dorsum, the median one narrow and sharply defined, the 

 lateral ones broad; dorsum somewhat dulled with yellowish polkni, 

 which is most conspicuous along the front; pleurae dulled with 

 white pollen. Abdomen green with coppery reflections; the usual 

 white pollen forming large conspicuous spots on the sides of the 

 segments; those on the sides of the fifth segment are sharply defined, 

 large, somewhat oval, and appear to be on a white ground color and 

 without the usual black hairs; those on the other segments are of the 

 usual character but with rather dense polleji. Hypopygium black 

 with green reflections on basal portion; its lamellae (fig. 210a) large, 

 somewhat quadrilateral, the upper and lower edges nearly parallel 

 and the apex truncate with a rather acute point extending from upper 

 corner; they are twice as long as wide, white with rather narrow black 

 border on apical and the outer half of upper margin, jagged and 

 bristly on apical margin, with long delicate yellowish hairs at the 

 extreme point and along the upper edge for a short distance; the rest 

 of upper edge with short black hairs; below they are fringed with a 

 few small pale hairs. 



Fore coxae wholly, middle and hin.d coxae largely yellow, the 

 middle and hind ones blackened on most of their outer surfaces; fore 

 coxae with anterior sm-face covered with minute yellow hairs, some- 

 times with a few black ones at base on outer edge; femora and tibiae 

 yellow. Middle and hind femora each with one preapical bristle, the 

 latter ciliated on lower inner edg(^ from before the middle r^early to 

 their tips with yellow hairs, these hairs of somewhat equal length 

 and about three-fourths as long as the width of the femora; they 

 are continued nearly to the base of the femora by very short yellow 

 hairs. Middle tibiae with tliree bristles below, two near apical 

 third and one near basal third, their basitarsi with one large bristle 

 above near apical third. Posterior tibiae a little thickened; the 

 usual glabrous stripe on upper surface is somewhat broken by a few 

 hairs, but is quite distin.ct and extends inside of the ir.ner row of large 

 ])ristles, quite widely so near the base. Fore tarsi (fig. 2106) one and 

 a half times as long as their -tibiae ; first two joints yellow, second 

 very thin, on.e-fourth longer than first, glabrous on the sides, with a 

 row of cor.spicuous, but short, black hairs, of uniform length on both 

 edges; last three joints black, compressed, taken together two-thirds 

 as long as first, third a little longer than fourth and slightly shorter 

 than fifth, a little widened, more so at tip, fourth slightly wider than 

 third, about as wide as long, fifth nearly orbicular in outline, tipped 

 with little white hairs, which are quite conspicuous. Middle and 

 hind tarsi black from the tip of the first joint, the former about one
