[LeConte. 



<3\ First ventral segment flattened at base; a^nal segment projecting 

 beyond the last ventral, and visible from beneath ; elytra not prolonged at 

 tip. 



9- Last ventral segment feebly channeled at the apex; elytra conjointly 

 prolonged at tip. 



Massachusetts to Georgia. Length 8 mm.; .31 inch. 



I know not why Gyllenhal placed this species among those in which the 

 third seventh joints of the funiculus are nodose ; they are in reality as 

 slender and subturbinate as in any of his first division . The synonym 

 seems to differ from the type only by smaller size and slightly irregular 



elytral puncturing ; similar variations occur in other species. 







3. L. tuberosus, n. sp. 



Black, densely clothed with yellowish-brown rounded scales, which be- 

 come larger on the prothorax, and hair-like upon the head. Beak as long 

 as the prothorax, stout, cylindrical, carina and grooves obsolete, frontal 

 fovea feeble. Prothorax as wide as long, sides nearly parallel, suddenly 

 rounded and narrowed near the tip, indistinctly trivittate with pale and 

 sprinkled with large distinct black dots. Scutellum pale. Elytra at base 

 broadly emarginate, burner! oblique, so that they become one-third wider 

 than the prothorax, sides gradually narrowed behind the widest part; pos- 

 terior callus large, conical, prominent ; striae punctured, interspaces wide 

 nearly flat ; scales uniform in color, very dense, setse very short. Beneath 

 of the same color as above, hind thighs with a pale band. Length 7 mm. ; 

 .28 inch. 



(5\ First ventral segment flattened at base, anal segment protuberant 

 beyond the fifth ventral and visible from beneath ; elytra rounded at tip. 



9 . Last ventral segment feebly impressed near the tip, each elytron pro- 

 longed at tip into a long straight process. 



Michigan to Georgia. Easily known by the absence of the carina and 

 grooves of the beak, which are so obvious in the two preceding species. 



4. L. squamiger (Say), Cure. 11 ; ed. Lee. i, 271, (Listroderes) ; Gyll. 

 Sch. Cure, ii, 279, Boh., ibid, vi, 189, partim. 



9- Last ventral with two strongly elevated folds at the tip, converging 

 towards the front, but not meeting, presenting the appearance of a deep 

 excavation; pygidium feebly channeled, rather pointed at tip ; elytra sepa- 

 rately acuminate, but not prolonged at tip ; ^ wanting. 



One 9> Georgia. Length 9.7 mm. ; .38 inch. The posterior callus of 

 the elytra is oblong, moderately prominent, but not a conical tuberosity as 

 in the three preceding species, since it graduates imperceptibly into the 

 fifth interspace. 



The 9 mentioned byBoheman in the last citation belongs to this species, 

 the supposed tf with caudate elytra is a 9 variety of L. inmqualipennis. 



5. L. callosus, n. sp. 



Blackish, densely clothed, as in the other species, with small rounded 

 scales, becoming larger on the prothorax, and hair-like upon the head,
