known to me in the elongate third joint of the antenna?. The speci- 

 men from the District of Columbia exactly resembles the Colorado 

 type, but has the beak still longer, two-thirds as long as the elytra, 

 smoother, more evenly arcuate, with the antennas inserted at apical 

 two-fifths ; it is without doubt the female. 



27 S. tychioides Leo.— Proo. Am. Phil. Soc, XV, p. 171. 



Oval, convex, shining, black, the elytra with a very feeble sub- 

 lateral rufescent vitta ; legs red, black near the coxae ; tarsi blackish ; 

 vestiture of the upper surface sparse and uneven, very fine and 

 sparse on the pronotum, yellowish and condensed in uneven sub- 

 transverse spots of coarse scales on the elytra, the interspaces thinly 

 sprinkled with fine short squamules ; under surface very densely 

 clothed throughout with small rounded yellowish-white scales. 

 Beak thick and gibbous toward base, strongly tapering, thin and 

 smooth toward apex, evenly, rather feebly arcuate, slightly longer 

 than the head and prothorax ; antennae inserted slightly beyond the 

 middle, the second funicular joint nearly as long as the next two. 

 Prothorax rather large, strongly convex, slightly wider than long, 

 strongly rounded at the sides, the latter moderately convergent, 

 broadly and just visibly sinuate near the apex; punctures reniform 

 or lunate, small, rather sparse, becoming larger and rugose laterally, 

 without trace of median line ; interspaces polished, not reticulate. 

 Elytra at base one-fourth wider than the prothorax, a little more 

 than twice as long, one-third longer than wide, elongate-ogival, 

 becoming almost parallel near the base. Length 2.2 mm.; width 

 1.1 mm. 



Kansas. I am not certain of the sex of the single example before 

 me, but the thick, strongly tapering beak would appear to indicate 

 the male. 



28 S. sagittatus n. sp. — Oblong-oval, convex, feebly shining, black, the 

 antennae piceous with the club paler ; legs and tarsi pale rufous, coxae darker ; 

 elytra black, with a broad pale rufous and oblique vitta on each from the 

 humeri to the apex ; vestiture almost entirely denuded in the type, but appa- 

 rently sparse and uneven as in tychioides. Head dull, the constriction moder- 

 ately strong ; beak thick, dull, equal in diameter and extremely feebly evenly 

 arcuate throughout, a little longer than the head and prothorax ; antennae 

 inserted at apical third, the second funicular joint but slightly longer than 

 the third. Prothorax moderate in size, convex, quite distinctly wider than 

 long, the sides evenly, rather strongly rounded, convergent but scarcely con- 

 stricted anteriorly ; disk dull, the sculpture fine, not very deep, extremely
