BARINI. 305 



basal angles not rounded, sides gradually narrowed and slightly rounded 

 to the tip; stria? fine, feebly punctured, ending near the base in deep fovere; 

 interspaces broad, flat, smooth. Antennae with the first joint of funii-Ie 

 scarcely longer than the second, but somewhat stouter than in the other two 

 species. Length 2.2 mm. ; .09 inch. 



St. Louis, Missouri; one specimen; Mr. M. Schuster. The prothorax is 

 more rapidly narrowed in Iront and more strongly tubulate than in any 

 other Curculionide known to me in our fauna. 



CALANDRINUS, n. g. 



The small insect which constitutes this genus bears a singular resem- 

 blance in miniature to Sphenophorus, but is clothed with scale-like hairs, 

 as in Centrinus. 



Beak slender, cylindrical, curved, as long as the head and prothorax, sep- 

 arated from the head by a transverse constriction ; head rather large, con- 

 vex; eyes distant, flat, pointed beneath, finely granulated; antennal grooves 

 descending obliquely towards the lower angle of the eyes. Antennae with 

 the scape not attaining the eyes; funicle 7-jointed, first joint as long as the 

 second and third united, but scarcely stouter; second longer than third; 

 3-7 gradually wider, merging into the club, w r hichis elongate-oval, pointed, 

 pubescent and annulated. Prothorax two-thirds as long as the elytra, 

 longer than wide, rounded on the sides, a little wider near the middle, nar- 

 rowed before the middle, constricted, but not tubulate towards the^ apex; 

 base broadly bisinuate, basal angles slightly obtuse, scutellar angle very 

 broad; postocular lobes wanting; prosternum long in front of the coxae,, 

 which are rather widely separated; scutellum very small, punctiform. 

 Elytra elongate-oval, a little wider than the prothorax, sides rounded, 

 forming an obtuse angle with the sides of the prothorax; stria? deep, not 

 punctured ; tips conjointly rounded, covering entirely the pygidium. 

 Middle and hind coxae widely separated; metasternuin short, ventral seg- 

 ments unequal, sutures angulated at the sides; fifth segment as long as the 

 two preceding united. Thighs moderately long; tibia? strongly unguicu- 

 late at tip; tarsi narrow, third joint scarcely wider than second, notbilobed, 

 last joint as long as the others united, claws simple, divergent, rather large. 



It is singular to find in this genus a recurrence of the narrow tarsi already 

 so frequently noticed in other tribes, without any important structural 

 modification, but with an outline of body suggestive of a very different 

 type. 



1. C. grandicollis, n. sp. 



Piceous, clothed with hair-like and narrow pale scales ; beak, antenna) 

 and legs brown. Beak not punctured, head sparsely punctured, with u 

 larger frontal puncture. Prothorax coarsely punctured, with an elongate, 

 smooth dorsal spot, attaining neither base nor tip; apical margin also 

 smooth. Elytra with deep impunctured striae, interspaces flat, each with 

 a row of deep punctures; third interspace wider, with the punctures eon- 

 fused. Beneath coarsely punctured. Length 3 mm. ; .12 inch.
