(which resemble obsolete vittae) on each side of basal half. The spaces 
separating these from the median area are most coarsely punctate. 
Basal margin strongly ^bisinuate. Scutellum broadly but not deeply 
channeled at middle. 
Elytra one-fifth wider than thorax, one-third longer than wide, moder- 
ately narrowed toward apex. Striae fine, very coarsely and sparsely 
punctate, with punctures nearly as wide as the intervals, which they 
distort. Intervals all convex except at base, strongly punctate; larger 
punctures foveate; i finely, closely, and irregularly biseriately punctate 
(sometimes uniseriately) ; 3 with two or three series of punctures in basal 
third or less and uniseriate in remainder; 5 and 7 narrower than 3, but 
similarly punctate; 2, 4 and 6 sparsely foveate-punctate, punctures more 
than one-third larger than on i, 3 and 5; remaining intervals except at 
base very irregular and obscured by coating. Pygidium much exserted, 
finely punctured in proximal portion; remainder coarsely, deeply, and 
irregularly punctate; golden yellow hairs forming tufts each side. 
Lower surface finely and sparsely punctate, varying as usual in the 
genus; legs strongly but rnuch more finely punctate, tibiae distinctly 
sinuate and somewhat densely fimbriate, with short black hairs. Third 
joint of tarsi: anterior and middle one-third, posterior one-fifth, wide 
than first joint. 
i fc.cJ*. Ventral concavity moderate, punctuation variable, disposed to be 
coarser than in female. Pygidium truncate at apex, with sides rounded. 
9 . First ventral segment strongly convex, the last with distinct 
fossa. Pygidium much narrowed at apex. 
Length 10.5-12 5 mm., width 3.9-4.8 mm.

Type. No. 8974, U. S. National Museum (j>). Cotypes 
in the collection of Mr. Frederick Blanchard, who has kindly 
divided his material with our National Museum. 
This species does not suggest any other in our fauna which 
has come to my notice. The projecting lower portion of the 
apical face of the thoracic constriction or collar is apparently 
peculiar to this species. 
Sphenophorus striatipennis, new species. 
Form of costipennis. General color red variegated with black, head 
and rostrum, median thoracic vitta, sutural intervals, abdominal seg- 
ments, metepisternum, coxae, knees, and tarsi black; somewhat weakly 
shining above, more polished on lower surface. Thoracic interspaces 
and elytral intervals with bright but light colored alutaceous coating. 
Rostrum less arcuate, not suddenly recurved and compressed in apical 
fourth; apex deeply concave on anterior face. Thorax less sinuate at 
base, median lobe more feebly prolonged; branch of lateral vitta less 
prominent. Elytral striae fine and distinct, punctures small, distinct and
