OUECfCTLIOKIDJB. [LeOonte. 



Middle and "Western States, not rare. Easily known by the separately 

 rounded elytral tips. There is no sexual difference in the position of the 

 antennae, but the beak is a little longer in 9 than in $. The antennae are 

 inserted about one-fifth the length from the tip. 



One tf from Georgia differs in having the punctures of the elytra less 

 distant, and the tips of the elytra more broadly rounded. It is perhaps a 

 distinct species. 



11 . L. rectus, n. sp. 



Elongate, finely pubescent, frequently pollinose, beak longer than the 

 prothorax, upper surface finely and densely punctured, punctulate beyond 

 the middle, antennae inserted about one-third from the tip. Prothorax longer 

 than wide, narrowed from the base, sides nearly straight, base emarginate 

 each side, medial angle prominent, obtuse, not rounded ; surface with ap- 

 proximate shallow punctures, interspaces finely punctured, dorsal concavity 

 long, triangular, deep towards the base. Elytra not wider than the pro- 

 thorax, striae composed of rather distant punctures, basal impressions deep, 

 tips separately rounded. Length 10.5 mm. ; .42 inch. 



One 9, New York. Allied to L, concavus, but narrower, with the pro- 

 thorax longer, and not rounded on the sides. I associate with this species 

 one (^ from Georgia, in which the beak is more pubescent, the antennae 

 less distant from the tip (about a quarter of the length), and the tips of the 

 elytra conjointly rounded. It may indicate a distinct species, but I am 

 unwilling to separate it at present. 



12. L. mucidus, n. sp. 



Large, rather robust, black, densely clothed with fine gray pubescence ; 

 beak longer than prothorax, upper surface densely finely punctulate, obso- 

 letely carinate behind the antennae, which are inserted about one-quarter 

 from the tip. Prothorax wider than long, rounded on the sides, scarcely 

 constricted at tip, densely finely punctured, and with scattered, larger, 

 tolerably deep punctures, base emarginate each side, medial angle prom- 

 inent, not rounded; dorsal excavation oval, deep. Elytra a little wider 

 than the prothorax, basal impressions wide not deep, striae composed of 

 moderately distant punctures, tip conjointly rounded. Length 14.5 mm.; 

 .57 inch. 



One pair, Illinois, in the $ the beak is more densely pubescent, and the 

 antennae are somewhat nearer the tip.

 Atlantic district, not rare. The beak is finely punctulate on the upper 



surface, the antennae are inserted in <^ about one -fourth, in 9 about one- 

 third from the tip; the punctures are denser in the former. The pro- 

 thorax is wider than long, rounded on the sides, distinctly constricted at 

 tip. The dorsal excavation is large, triangular and deep. The basal im- 

 pressions of the elytra are also deep, and the tips are conjointly rounded.
