336 MEMOIRS ON THE COLEOPTERA 



nearly similar, finely, sparsely punctate, with coarser punctures 

 aggregated near the base; elytra longer, parallel (9) or feebly 

 cuneiform (cf ), the punctures similarly coarse, deep and perforate, 

 well separated, the outer raised line distinct before the middle nearly 

 to the humeri; femora strongly clavate in both sexes; female with 

 the fifth ventral very deeply emarginate at tip, the emargination 

 fringed with long dense white hairs, the last dorsal segment rapidly 

 narrowing to a point some distance from the tip, thence narrow and 

 parallel to the acute or narrowly blunt apex; male with the fifth 

 ventral more shallowly sinuate at tip, the last dorsal short, very 

 narrowly, deeply and acutely incised medially, the lobes rounded. 

 Length (cf 9) 14.0-15.5 mm.; width 4.6-4.9 mm. Florida. 



floridanus n. sp. 



4 Antennae (cf ) not or but little more than twice as long as the body, 

 the outer joints not increasing noticeably in length 5 



Antennae (cf ) two and one-half to nearly three times as long as the body, 

 the outer joints distinctly increasing in length 6 



5 Last antennal joint (cf ) without trace of a terminal process. Body 

 oblong, not very elongate, feebly convex, the elytra slightly cuneiform 

 in both sexes, blackish, clothed with cinereous vestiture, variegated 

 very confusedly with blackish spots; head with a deep entire median 

 stria; lower lobe of the eyes elongate; antennae slender, the joints 

 cinereous at base, three-fourths longer than the body in the female; 

 prothorax short, not quite twice as wide as long, the lateral spicule 

 near basal third; surface nearly even, the anterior tumidities almost 

 obsolete, rather finely and not densely punctate, with four ochreous 

 spots anteriorly in transverse line, broadly concave and a little more 

 punctate at base; elytra less than two and one-half times as long as 

 wide, wider than the prothorax, the apices broadly rounded, the 

 elevated lines obsolete but with the lineate black spots rather con- 

 spicuous, mingled with many other small black spots, the ante- 

 median oblique fascia very indistinct, the post-median, and a sub- 

 sutural spot near the apex, rather well defined; punctures moderate, 

 very deep and close-set basally, sparse and less distinct apically; 

 female with the last dorsal flat, narrow, gradually cuneiform to the 

 obtuse apex, the moderately produced last ventral with the rather 

 narrow emargination bearing a long dense fringe of whitish hairs; 

 male with the supplementary last dorsal bilobed, sinuate medially. 

 Length (cf 9 ) 8.5-11.0 mm.; width 2.6-3.2 mm. Maine (Mon- 

 mouth), C. A. Frost pusillus Kirby 



Last antennal joint (cf) with a distinct terminal appendage, which 

 however is short, not much over four times as long as wide. Body 

 rather narrower and more convex, black, with dusky maculation, 

 together with some cinereous, especially separating the conspicuous 

 small black spots of the strongly elevated elytral lines; head strongly 

 impressed, the stria obsolete near the antennal tubercles, the lower 

 lobe of the eyes broader, only a little longer than wide; antennae (cf ) 

 twice as long as the body, the joints cinereous in basal half; prothorax 

 three-fifths wider than long, the spicules just before basal third; 

 surface strongly but very sparsely punctate and with two antero-
