and the lack of hirsute adornment on the venter and appendages. 
As L. tetrops Lea has not been, to my knowledge, figured, I ap-

Figs. 3, 3a, $ ; 4, 4a, $ 
Robust, ovate, piceous. 
$ Head transverso-quadrate, anterad nearly straight, antero- 
lateral angles rounded, canthus and post-ocular process pro- 
duced; clypeus broad, feebly trilobate; canthus emarginate and 
rounded, post-ocular process acuminate; eyes fairly small; 
mentum twice as broad as long, feebly lobed in front, laterad 
broadly rounded, sloping toward the center and front, strongly 
cribrate-punctate, more so on the sides. Front strongly de- 
clivate, subcarinate on vertex, beset with circular large pits 
(pockmarked), which become much larger and closer on the 
vertex and occiput. Mandibles porrect, arcuate, apices acute, 
finely remote punctulate, shining above, opaque beneath; outer 
margins rounded, with a median erect tooth; inner edge, in 
center, with a broad laminate process, which has on the left 
mandible two, on the right one, feeble indentation; between the 
central lamina and the base a circular excision, which, when 
mandibles are in repose, forms a top-like opening; base with 
an acute, diagonally forward pointing tooth and, above it, a 
deep excavation. Prothorax broad, anterior angles produced 
and nearly square, sides subparallel to posterior angles, latter 
diagonally truncate, base straight; nearly explanate on top, 
sides sloping, remotely punctured; disc with a central, ovate, 
strongly punctured depression and, laterad, right and left, two 
smaller ones; base, opposite the scutellum, with a triangular 
fovea. Scutellum small, broader than long, apex subacute, cen- 
ter with a transverse fovea. Elytra ovate, broadest beyond the 
middle, apex acutely rounded; humeri produced, mucronate; 
each elytron with two obsolete costae, densely covered with 
large, ovate pits, becoming smaller and closer toward margin;
