3 and 4, on apical portio'i. with silvery pile, which, when the insect is held iu 

 certain lights, appears to cover tliese segments entirely. Wings flavo-hyaline, 

 uervures ferruginous, the apical third a little darker; dorsulura clothed with 

 golden pubescence, which is most dense on the sides and posteriorly. Length

9 . — Anterior margin of clypeus in the middle with a very slight incurvation, 

 which is more distinct when viewed from behind, or entire, the large extreme 

 lateral tooth is situated in an emargination ; third joint of antennse distinctly 

 longer than the fourth, the fourth and fifth about equal ; vertex with exceedingly 

 fine and close punctures, the median impressed line distinct. Thorax punctured 

 like the vertex, the metanotnm even more closely so; dorsuium but little de- 

 pressed in the middle, anteriorly ; scutellum without medial impression ; meta- 

 notuni with an exceedingly slight, impressed line, in most specimens without 

 any trace of a line, at the apex with a strong, pyriforra fovea; posterior face 

 with a very strong medial sulcus, which does not extend to the apex ; tibife and 

 tarsi armed with a stout thorn ; ventral abdominal segments 3 — 5 with large, 

 sparse punctures, black ; basal half of mandibles, palpi, scape beneath in part, 

 tegulaeand legs, except coxae and trochanters, ferruginous; front, clypeus, cheeks, 

 collar and mesopleurse with long, silvery pubescence ; dorsuium, especially on 

 the sides, postscutellum and apex of metapleurse with golden pubescence ; femora, 

 with exception of a silvery pile, nude ; dorsal abdominal segments 1 — 3 with 

 their apical margins silvery; apical margins of ventral segments in some speci- 

 mens are j-eddish. Wings flavo-hyaline, apical margins darker, uervures ferru- 

 ginous. Length 15 — 21 mm.

I have been unable to identify the typical form of this species, 

 which is said to have the femora black ; all my specimens belong to 

 the var. B of Smith, having the femora reddish. It is probable 

 Smith has confused two species here.

% . — Clypeus broadly produced, the production rounded at apex or snbtruncate ; 

 vertex finely punctured, the medial impression very strong; none of the joints 

 of flagellum rounded out beneath; space between eyes at top not equaling the 

 length of the second and third joints of antennte. Thorax punctured like the 

 vertex: dorsuium anteriorly, in the middle not strongly depres.sed ; scutellum 

 without impression; metanotum with an exceedingly slight, impressed line, the 

 fovea at apex strong and variable in form ; four posterior tibia armed with 

 tolerably stout thorns. Abdomen above and beneath with exceedingly fine and 

 close punctures, those beneath a trifle more distinct; eighth ventral segment 

 with a broad, round emargination, black; mandibles, except apical portion, 

 palpi, knees, tibite, tarsi and the tegulse ferruginous; front, clypeus, scape and 

 dorsuium on sides with long, pale pubescence ; cheeks, collar, pleurse, metathorax 

 and first segment of abdomen with griseous pubescence ; dorsal segments 1 — 4
