the exterior margin a lateral, laminate, obtuse tooth and, an- 
terad, near the apical third, a superior, subacute tooth. Pro- 
thorax one and one half times broader than long, front margin 
gently bisinuate, anterior angles rounded, diverging diagonally 
to the middle, thence nearly parallel to posterior angles, latter 
broadly rounded, base nearly straight; disc with an oblong 
median depression and, postero-laterad, circular impression. 
Scutellum broad, apex rounded, base impunctate, with an 
irregular impressed line, which circumscribes, in the apical area, 
five unequal punctures. Elytra with humeral angles broadly 
rounded, sides parallel, apex regularly rounded, suture with an 
ill-defined costa and each elytron with two irregular costae, 
terminating on the posterior declivity. Beneath, densely clothed 
with long grayish pubescence; abdominal segments nearly ex- 
planate, feebly emarginate, confluently punctate; posterior seg- 
ment slightly convex. Intermediate and posterior tibiae serrate, 
with a prominent spine near the apical third ; spurs well devel- 
oped; tarsi short and fairly stout, ultimate segment nearly as 
long as the others combined. 
$ Of the same general appearance as the male, but with 
head smaller (2 : 1), with frontal margin slightly transverso- 
carinate, mandibles shorter than the head, with a central bicus- 
pid tooth on the inferior edge, thorax narrower in front and 
longer than wide, stouter legs, less prominent spines, etc. 
Dimensions: S 12.5 mm. long, mand. inch; width, 4.5 mm. 
$ 13.75 mm. long, mand. inch; width, 5.6 mm.

Allied to Ceratognathus bitumulatus Carter, from which it 
can be readily distinguished by the shape of the mandibles, 
squamae, non-tumulate elytra, etc. The female here figured has 
asymmetrical margins on the pronotum; left margin has a slight 
protuberance, which is missing on the opposite side, as indi- 
cated by the broken line in the drawing. Described from a pair 
of (rather dilapidated) examples; the male is minus left an- 
tenna, anterior tibiae, right intermediate leg and all tarsi; the
