Sphenophorus graminis, new species. 
Black, moderately shining without coating, of robust appearance due 
to the elytra being much wider than the thorax. 
Rostrum less than two-thirds as long as the thorax, robust, moderately 
arcuate, much compressed, most strongly at the apex; base moderately 
wide, suddenly and strongly dilated over the scrobes with dilated portion 
angular, very feebly or scarcely conaliculate ; interocular fossa round, 
shallow, sometimes indistinct; impressed line more or less indistinct, 
scarcely longer than the width of the rostrum over the scrobes; apex 
with a shallow concave triangular space on anterior face, subacutely 
rectangular on posterior face; surface finely moderately and densely 
punctate, gradually coarser in basal half. Head feebly, very sparsely 
punctulate. 
Thorax (without apical constriction) nearly as wide as long, apical 
half arcuate, apical constriction strong; base distinctly bisinuate; surface 
somewhat densely and finely punctate, punctures nearly uniform 
except along the median line where there is a small narrow smooth 
space of varying extent (sometimes nearly absent) and at the middle 
of the basal margin where they are a little coarser and denser. Scutellum 
feebly concave or nearly flat. 
Elytra about one-third wider than thorax and scarcely one-fourth 
longer than wide, moderately narrowed at apex; striae finely uniformly 
punctate, punctures not visible on the surface, sutural stria strongly 
curved outwardly at base; intervals flat, alternate in width, narrower 
ones finely uniseriately punctate, wider ones with two or three rows 
of similar punctures, antepenultimate interval depressed more or less 
strongly. Pygidium finely moderately densely punctate, each puncture 
with a short pale yellowish gray seta, apical tufts wholly wanting or 
exceedingly minute. 
Lower surface finely, nearly uniformly punctate, punctures shallow 
and more dense than on thorax. Legs more sparsely and finely punctate 
than on thorax; tibiae feebly sinuate on inner surface and sparsely fim- 
briate; anterior tibiae with outer angle considerably prolonged. Anterior 
tarsi with third joint less than one-third wider than first. 
<3\ Ventral concavity broad and shallow. 
9 .First and second abdominal segments connate or subconnate at 
middle. Pygidium comparatively broad. 
Length 7-9 mm., width 2.8-3.8 mm.
