tance from the inner orbits on the upper portion of the curved 
slope which leads into the deep transverse depression that 
separates the front from the face; basal segment short, much 
thicker than long, widened and crescent-shaped at the apex; 
second segment disk-shaped, almost circular from the side, as 
long as the first; third segment apparently fused with the style, 
the whole being over twice the length of the two basal segments 
together, extremely slender and narrow, strongly tapering from 
the basal third to the apex which is very' sharply pointed 
Front regularly curved from vertex to antennae, below which it 
droops deeply into a very pronounced transverse groove sep-

arating the face. Face sunken between the eyes, the median, 
shorter portion sharply divided from the lateral areas by deep, 
vertical grooves. Palpi and proboscis if present, extremely 
reduced and not to be distinguished among the long pilosity. 
Body broad and thickset. Thorax about as thick as, but shorter 
than, wide; its dorsum distinctly convex. Transverse suture 
well-marked on the sides over less than one-third of the width of 
the dorsum, obliquely continued behind to a short distance from 
the scutellum. Scutellum large, nearly elliptical, its posterior 
margin not separated from the disk. Abdomen broad and 
short, but little longer than wide, quite convex dorsally and 
somewhat curved down at the apex. The several segments 
are distinctly constricted, their apical portion being slightly 
swollen. The first tergite is very short and mostly covered by 
the scutellum. Second tergite much the longest, about as long 
as the two following tergites together; in its basal half it is 
broadly grooved transversally, the bottom of the channel being
