NORTH AMERICAN COLEOPTERA. 25 



base about equal to the distance to the eyes ; thorax a little longer than wide, 

 slightly narrowed in front, the sides nearly straight, slightly arcuate in front, 

 disc convex, moderately, coarsely and densely punctate ; elytra finely striate, the 

 intervals flat, moderately densely punctate, slightly rugose at base ; body be- 

 neath moderately densely punctured, the punctuation finer than above ; an- 

 tennal groove deep, sharply limited ; last ventral segment acute at apex ; claws 

 broader at base, but not toothed. Length .32 - .44 inch ; 8-11 mm. 



This species is well known to nearly all collectors. The larva has 

 been found by me in decaying oak. By the great kindness of my 

 friend Salle, I have examined the actual type of Dromseolus novitius 

 Bonv. and find that it is merely a darker form of the present sjDecies. 



Occurs from Pennsylvania to Illinois and Louisiana. 



F. Ilornii Bonv. — Form oblong, moderately robust, piceous, or nearly black, 

 sparsely clothed with short fulvous pubescence ; antenufe brownish, extending 

 a little beyond the hind angles of the thorax, very feebly serrate, second joint 

 as long as the fourth, third a little longer, joints 4-11 gradually a very little 

 longer ; head convex, coarsely and densely punctured, a distinct frontal carina 

 between the bases of the auteunse ; clypeus at base less than a third the width 

 of the apex and less than half the distance to the eyes ; thorax as long as wide, 

 sides posteriorly parallel, anteriorly arcuately narrowing to the front, disc con- 

 vex, coarsely and densely punctured, a slight depression at the middle of the 

 base ; elytra striate, faintly at middle, more deeply at the sides, densely subru- 

 gosely punctate ; body beneath rather densely punctate ; antennal groove deep, 

 sharply limited ; posterior coxal plate rather abruptly broader at middle ; last 

 ventral segment oval at tip ; legs ferruginous ; claws simple. Length .28 - 32 

 inch ; 7 - 8 mm. 



This species resembles calceatvs, but is usually more robust and larger, 

 the punctuation finer and the second joint of the antennae shorter. 



In his description of this species in the concluding paragraph 

 (p. 893) Bonvouloir speaks of F. basalw Lee. when he plainly refers 

 to this species. He also quotes the locality " California" in error. 



Occurs in Canada and Kentucky. 



F. ealceatus Say. — -Form oblong, moderately convex, dark brown or pice- 

 ous, feebly shining, sparsely clothed with short yellowish pubescence; antenufe 

 nearly half as long as the body, slender, second joint shorter than the fourth, 

 joints 4-11 gradually slightly longer; head coarsely, deeply and roughly punc- 

 tured, a small, smooth longitudinal space on the front, a distinct transverse 

 carina between the bases of the antennse ; clypeus very narrow at base, scarcely 

 a fourth either of its apex or the distance to the eyes ; thorax longer than wide, 

 distinctly narrower in front, sides posteriorly straight, arcuate at apical third, 

 disc convex, a slight median depression at base, surface coarsely, densely and 

 roughly punctured ; elj'tra narrowed at apical third, faintly striate, surface 

 coarsely, roughly and moderately densely punctured, but less coarsely than 

 above ; antennal groove deep and sharply limited ; posterior coxal plates grad- 

 ually, but rather widely dilated; tarsal claws simple. Length .20 -.24 inch ; 

 5-6 mm.
