OF WASHINGTON. 179 
Thorax longer than wide, posterior three-fourths moderately arcuate 
apical constriction very feebly, , surf ace very coarsely, densely, unevenly 
punctate, punctures frequently confluent. The median vitta takes the 
form of an irregular smooth, unelevated space of varying length, and ot 
a width about the same as an elytral interval; lateral vittae absent 
Scutellum sulcate with median line. 
Elytral striae irregularly, very deeply, coarsely, confluently punctate 
in the basal portion, becoming very narrow toward the apex. Intervals 
irregularly alternate in width and convexity, i, 5, 7 uniseriately punctate 
except in the basal portion, third interval wider and distinctly biseriate 
in basal half; intervals 2, 4, 6 more coarsely and sparsely punctate. 
Pygidium subtriangular, as long as wide at base; apex subacute, hairs 
whitish gray, apical tufts minute but distinct. 
Lower surface moderately coarsely and moderately sparsely punctate. 
Anterior and middle tibiae with the outer angle somewhat feebly prolonged. 
Anterior and middle tarsi with third joint strongly, of the posterior feebly, 
dilated. 
Length 7.5 mm., width 3.8 mm.

Type. No. 8973, U. S. National Museum. 
Sphenophorus blanchardi, new species. 
Form moderately robust, resembling scoparius in size and proportions 
general color subopaque black on dorsal, moderately shining on ventral, 
surface. Larger punctures filled with gray extraneous argillaceous 
material. Antennae and tarsi slightly piceous, nearly black. 
Rostrum two-thirds as long as thorax, moderately, nearly uniformly 
arcuate, except at base and apex, where it is perceptibly and about 
equally compressed. Base strongly dilated, fully twice as wide as at 
middle of rostrum, strongly and angulately dilated over scrobes; basal 
fossa large, deep and broad near head, usually ending in a distinct line 
beyond dilated portion of rostrum. Apex flattened on anterior face, 
usually concave, on posterior face more or less strongly and acutely 
produced. Surface strongly punctate, very coarsely at base and finely 
at apex. 
Thorax about one-fourth longer than wide, moderately arcuate at 
sides; apex strongly constricted, with the extreme apical margin also 
strongly constricted on each side, the lower portion projecting beyond 
the upper. Surface very coarsely foveate-punctate, more finely on a 
slightly elevated area just in front of middle, and on two variable areas
