Type. No. 8969, U. S. National Museum. 
The very close resemblance of this species to graminis is 
remarkable, considering the difference in the tarsal structure. 
There is a tendency toward a second row of punctures on the 
narrower elytral intervals and the outer angle of the anterior 
tibiae is of variable length In one individual the legs are 
dark rufous. There is considerable variation also in the width 
of the third joint of the anterior tarsi, but these and other 
variations from the type ate perhaps individual, although the 
presence, of a larger series with definite localities may show 
that there are two species included under this name. 
As to habits, the only available data are that it was 
collected by Mr. Schwarz associated with 5. oclireus in wet 
ground on the banks of irrigating ditches, on the roots of a 
rush of unknown species. 
Sphenophorus diversus, new species. 
Slender, black, with antennae, portions of legs, apex of abdomen at 
sides, and margins of elytra, piceous. 
Rostrum less than half as long as thorax, moderately arcuate and 
compressed, more strongly at apex than at base; apex flat on anterior 
face, rectangular on posterior aspect; at base fully twice as wide as at 
middle, strongly dilated above scrobes with acute angles; interocular 
fossa round and deep; scarcely canaliculate, and with impressed line 
faint, very short, about twice as long as the diameter of the interocular 
fossa. Surface coarsely but sparsely punctate, gradually becoming finer 
to the apex. 
Thorax fully one-third as long as wide; apical constriction moderate; 
sides' moderately arcuate. Vittae somewhat distinctly indicated by 
smoother, more finely and sparsely punctate areas, elevated in their 
posterior half; median extending from base to apical constriction, nar- 
rowed at each end to about half the width of the scutellum, widely and 
somewhat suddenly dilated at a point behind the middle, and becoming 
confluent with the lateral vittae Justin front of the middle. Interspaces
