592 Coleopterological Notices, IV. 



This species is so well known, and so easily recognizable by the 

 characters given in the table, that but little further need be said of 

 it. The antenna? are slender, rather long, the second funicular joint- 

 very slender, fully two-thirds as long as the first and scarcely as 

 long as the next two together, the latter equal and each distinctly 

 elongate, the club small, rather abrupt, elongate-oval, pointed and 

 but slightly longer than the three preceding joints combined, densely 

 pubescent and with its basal joint constituting scarcely two-fifths of 

 the mass ; the scape is slender, rather abruptly clavate and inserted 

 just beyond basal third. The prosternum is flat, extremely densely 

 squamose, feebly bitumorose at the apex, and with a transverse ex- 

 cavated groove at a sensible distance behind the apical margin, the 

 coxae rather large, somewhat prominent and separated by barely 

 two-thirds of their own width. Anterior trochanters small and 

 simple in both sexes. Length 3.5-3.8 mm.; width 1.7-1.9 mm. 



The series before me is from Iowa and Indiana. I have seen no 

 specimen in which the apical subsutural denuded spots were com- 

 pletely wanting, but the others are frequently obliterated. It is 

 probable that the Cuban tomentosus Klug, i. litt., is a different 

 species from this.

20 Centrinus lineellus Lee. — Proc. Ac. Nat. Sci., Phila., 1859, p. 79. 



A finely ornamented small species of rather robust, oval, convex 

 form, black throughout, the antennal scape rufous; under surface 

 clothed densely with large yellowish-white scales, the same forming 

 three distinctly limited broad vittae on the pronotum, and covering 

 the second elytral interval throughout, the third in apical two-thirds, 

 the fourth in basal fourth, the sixth more or less throughout, and 

 the seventh and eighth except toward the humeri ; remainder of the 

 upper surface clothed with large piceous-black scales. Beak in the 

 female slender, evenly and extremely arcuate, a little more than 

 one-half as long as the body, the antennas inserted just behind the 

 middle, the scape short, extending thence only two-thirds the dis- 

 tance to the eyes, the seconcl funicular joint slender, a little more 

 than one-half as long as the first and distinctly shorter than the 

 next two, the latter subequal and each a little longer than wide, 

 outer joints gradually and distinctly transverse, the club small, 

 narrowly oval, not very abrupt, densely pubescent, as long as the 

 preceding four joints combined, and with the basal joint composing
