in portions of Missouri from 1884 to 1903, and to chufa (Cyperus 
esculentus) in Oklahoma. 
Sphenophorus sublaevis, new species. 
Very .similar to the above but distinguishable by its uniform dull black 
color due to the absence of argillaceous coating and by having much 
deeper, coarsely foveate punctures on the entire dorsal surface. The 
rostrum is more protuberant in front of the eyes, more strongly compressed, 
and the apex is acutely or subacutely angled posteriorly. The elevated 
portions of the thoracic vittae are much wider, without elevated lines. 
The four fossae are scarcely indicated. The elytral surface is much more 
irregular and the very deep and large strial punctures and more minute 
punctures of the intervals are conspicuous. The apical tibial spurs are 
very long as are the subapical spurs, the latter being nearly as thick 
and half as long in the anterior pair. Pygidium with much paler, scarcely 
yellow hairs. Sexual characters about as in destructor. 
Length 9-10 mm., width 3.5-4.2 mm.

This species was united by Le- 
Conte 1 and Horn with cariosus Ol., 
but wrongly so, as I shall attempt 
to prove. Olivier's description 
reads in substance as follows: 
Body black with dark cinereous coat- 
ing. Antennae brownish black, shining, 
cinereous at apex. Rostrum black, dark 
cinereous at base. Thorax uneven, "and 
one sees on t ^ ie su P er i r portion an ele- 
vation in the form of a cross> feebly 
marked." Elytra uneven, feebly vario- 
late, marked toward the apex with a 
callous point, nearly spinose, blackish, 
shining. 
Olivier's illustration is imperfect 
in that it is very crude, showing 
neither punctuation nor sculpture and the general impres-
