easily discoverable, being a round, impressed spot, some distance in ad- 
vance of the end of the vertical prominence. The front edge of the 
epicraniam is broad, the front or square edge extending on each side to 
the posterior region of the head.

The clypeus, or piece to which the upper lip (labrum) is attached, is 
faintly divided by a broad, slight furrow into a basal and an anterior 
portion, the latter part raised and sinuous on the front edge, while the 
sides of the clypeus are bounded by the base of the mandibles. 
The upper lip (labrum) is rounded pad-like, as long as broad, moving 
freely on the clypeus, so that when the jaws are opened widely the la- 
brum drops down between them. 
The antennae are very long and slender, reaching to the base of the 
ovipositor, with the second joint (of the scape) large and flat. 
The jaws (mandibles) are very large and stout, the ends when closed
