the process very narrow and sublamellar. The male characters are 
always pronounced and generally affect both the clypeus and thoracic 
apex, but these characters greatly diminish in degree in the smaller and 
less developed males, these depauperate individuals not differing much 
from the females in either the present genus or Ceracis. In both of 
these genera the male also has a small deep pubescent fovea, not at the 
centre, but near the posterior margin, of the first ventral segment, 
characters of the following table are taken throughout from what appear 
to be fully developed males only:— 
Male with the clypeal margin broadly and strongly reflexed in a trapezoidal process, the 
thoracic process bidentate.. *' * * 
Male with a long slender erect clypeal process, the thoracic apex simple and rounded; 
species very small. 
2— Elytra without trace of impressed lines.* * * * * * * 
Elytra with very feebly and unevenly impressed lines, the punctures feebly sub¬ 
serial in arrangement.*. 
3— Male with the thoracic processes longer, narrower and more approximate ; punc¬ 
tuation feeble, the elytral punctures always confused in arrangement. Atlantic 
and Gulf regions.*. *'' 
Male with the thoracic processes shorter, more widely separated and more lamellarly 
triangular ; punctuation stronger, the elytral punctures generally confused but 
occasionally very feebly subserial. Pacific Coast regions. 
4— Apex of the pronotum rather feebly impressed behind the processes. 5 
Apex of the pronotum strongly, transversely impressed behind the processes. Mod¬ 
erately slender, polished, piceo rufous in color ; head well developed, concave, 
tie clypeal process large and well developed, with the apex feebly sinuate at 
the middle; prothorax slightly wider than long, the sides parallel and nearly 
straight, the angles all rounded ; processes long, slender and distinctly diverging 
as usual; base and sides finely margined ; punctures fine and sparse ; elytra less 
than one-half longer than wide, as wide as the prothorax and two-thirds longer, 
the surface very feebly subrugulose, sparsely and very minutely punctate, the 
punctures much more minute than those of the pronotum ; apex evenly rounded.

rather strongly shining ; legs, mouth parts and antennse pale ; punctures fine and 
rather sparse ; thoracic processes rather short. Canada to Pennsylvania (melljt

Elytra very short and quite strongly cunei f orm, very much less than one half longer 
than the prothorax. Rather stout, the head polished and concave, the eyes 
small; clypeal process well developed but with the sinuate sides rather rapidly 
converging, the apex a little less than half as wide as the head, feebly sinuate* 
truncate ; prothorax large, not quite as long as wide, the sides parallel and 
broadly arcuate, the corneous processes moderately long and rather stout, 
punctures fine but distinct, only moderately sparse ; elytra at base as wide as the
