tubercle but above extending on either side of the antennae to 
the blue black front. Sides of the front linearly yellowish and 
with a narrow eye-marginal stripe on the upper part of the 
front which is silver pubescent. The upper third of the triangle 
of the front is opaque black and long, erect black pilose, the 
pile largely confined to areas along the eye margin and extend- 
ing down to the upper part of the face, lower facial pile white. 
Antennae black, the third joint reddish below. Arista blackish 
except at base. Occipital pile black above, black in the middle 
excavation and composed of practically a single row of sparse 
yellow hairs. Thorax: dark sepia-brown, moderately shining 
with a slight violaceous narrow vittae sublaterally on either 
side of the mesonotum. Pile short, erect, black and quite sparse.

stripe. Scutellum dark brassy-brown, its pile short, erect and 
very sparse, its ventral fringe of ten or twelve hairs pale. 
Abdomen: elongate and spatulate and almost wholly brownish- 
black, the second segment very little narrower than its apex 
and a little over six times as long as its subbasal width. The 
apex of the third segment is two and a half times or more wider 
than its base. Fourth segment almost quadrilateral and barely 
wider apically. Second segment with a wide, medial, subbasal 
opaque black vittae which apically expands to form a subapical 
fascia some distance from the apex. It is posteriorly indented. 
All of the third segment black except for prolonged basal and 
lateral triangles and for an apical margin laterally attenuated. 
Middle of the opaque black with a pair of small, slender, yel- 
lowish vittate spots. Fourth segment opaque black except for 
narrow basal triangles and a narrow posterior margin widest 
in the middle. There are similar spots centrally on the fourth 
segment. There are three, oval, elongate, basal opaque black 
spots on the fifth segment. The pile of the abdomen is ap- 
pressed and black but whitish and long on the sides of the 
first segment, shorter and white on the sides of the second. 
Legs: dark brown, the base of the first four tibiae diffusely and 
obscurely paler; the medial surface of the anterior femora is 
yellowish-brown, the hind tibiae and basal two-thirds of the 
hind basi tarsi black and black pilose, their remaining tarsi 
yellowish-white, the other tarsi dark brown. Pile of hind
