OF WASHINGTON. 55 
Sphenophorus setiger, new species. 
Similar to ludomcianus, but smaller and proportionately more robust. 
General color black, with cinereous or gray-brown alutaceous coating. 
Rostrum shorter, three-fourths to four-fifths as long as thorax, otherwise 
scarcely different. Elytra more nearly opaque than shining; striae more 
distinct ; intervals unequal in width and convexity, smaller (even) intervals 
less developed, and variable in convexity; elevated shining black portions 
as follows: 2 a thin, slightly interrupted line half as long as i ; 4 a little 
wider and longer; 6 short or wanting; sometimes i, 3 and 5 are the only 
intervals that are black. Lower surface less strongly punctate. 
cT. Rostrum a little shorter and more slender, thorax scarcely narrower 
anteriorly than in $ ; ventral concavity deep and broad; metasternum 
with a row of short brown setae just within the lateral margin, a few minute 
setae each side of the first abdominal segment, second with a transverse 
brush of longer dark ochraceous hairs. Fossa of last ventral segment of 
variable depth, usually more shallow than in ludomcianus. 
$ . Scarcely larger than the male, otherwise as in ludomcianus, which is 
true of most other obvious characters that have not been described. 
Length 10.0-12.5 mm., width 4.0-5.2 mm.

Type. No. 8223, U. S. National Museum. 
Sphenophorus ludovicianus, new species. 
Of the same form as pertinax, but larger, with all elytral intervals black 
and convex. General color polished black, with a natural ochraceous 
alutaceous coating which covers the thoracic interspaces, elytral striae, 
inner surface of the tibiae, the pygidium, and the larger punctured areas. 
Head finely sparsely punctulate. Rostrum the same length as, or 
scarcely shorter than, the thorax, slender, moderately dilated at base and at 
apex, moderately compressed, a little more strongly at the apex, moder- 
ately arcuate, more distinctly toward apex; surface finely punctulate, at 
base more coarsely and distinctly; base distinctly channeled with distinct 
interocular puncture, the whole forming a lanceolate depression terminat- 
ing apically in a short impressed line. 
Thorax a little longer than wide, strongly arcuate at the sides, moderately 
constricted at apex, basal half subparallel but somewhat constricted at ex- 
treme base; surface with three feebly or moderately elevated, entire, 
nearly smooth, broad vittae; median vitta strongly and suddenly dilated 
just in front of middle, the apical half forming a wide cuneiform or trian- 
gular space, basal half narrower toward base; lateral vittae nearly as wide
