the head is kidney-shaped and nearly twice as wide as high in 
the middle. Front rather wide, broadest at the insertion of the 
antennae where it measures a little over half the width of the eye; 
inner orbits moderately converging toward the anterior ocellus, 
where the front is slightly over half as wide as at the antennae. 
Sides of the vertex parallel. Ocellar tubercle short and flat, with 
a slight transverse depression below its middle, hardly separated 
by a notch from the inner orbits; ocelli placed in a short isos- 
celes triangle, the posterior ocelli distinctly, but slightly, closer 
to each other than to the anterior ocellqs; anterior ocellus larger 
than, though not quite twice the size of, a posterior ocellus, 
short elliptical, occupying a little less than one-third of the 
width of the front. Eyes bare. Antennae (Fig. 16) short, small, 
placed on the sides of the face, close to the inner orbits; basal 
segment cylindrical, nearly one and a half times as long as wide, 
squarely truncate at apex; second segment but little shorter 
than the first, slightly longer than wide, broadly truncate at 
apex; third segment much flattened, very elongate pear-shaped, 
over twice as long as wide, much longer than the two basal 
segments together, widest in its basal half and thence rather 
rapidly tapering to the straightly truncate, narrow apex. Style 
about the length of the whole antenna, only two-jointed; the 
basal division a little shorter than the second antennal segment. 
Front very feebly convex between anterior ocellus and antennae. 
Face moderately swollen, forming a low, blunt cone, without 
grooves. The lower portion of the head is but slightly and very 
broadly excavated in the middle between the cheeks. Proboscis 
very long and slender, reaching about the tip of the abdomen 
when folded beneath the body; in the specimen in hand it is 
directed vertically downward, with the apical third curved 
forward; labella very thin and elongate. Palpi short and slender, 
three-jointed; the two apical segments much longer and of about 
equal length; the third obtuse at apex. Body rather thickset. 
Thorax about as wide as thick; dorsum nearly square; trans- 
verse suture deep on the sides over about one-third of the width 
of dorsum, continued backward to near the scutellum. Scu- 
tellum large, semi-elliptical, its posterior margin distinctly 
separated from the disk by an impressed line. Abdomen flat-
