60 MEMOIRS ON THE COLEOPTERA 



surface and legs ochraceous; head less than half as wide as the pro- 

 thorax, the eyes moderate, the antennae slender and rather long; pro- 

 thorax with minute and subobsolete strigilation throughout, the base 

 finely but distinctly margined medially, but barely visibly and broadly 

 lobed, short, much more than twice as wide as long; scutellum ogival, 

 paralleled by the fine basal stria of the elytra, which are but slightly 

 elongate, obtusely parabolic, the entire surface with minute, trans- 

 versely wavy feeble strigilation and with a few extremely minute 

 punctules, arranged in feebly defined series; stria deeply impressed; 

 prosternal process with about four terminal bristles. Male with 

 sexual characters as in viduus. Length 1.65-1.8 mm.; width 0.9- 

 1.05 mm. Four examples, received from Mr. Meeske, who thought 



that they were taken near New York City ludibundus n. sp. 



Form rather broadly oval, convex, very shining, widest near the base of 

 the elytra, rufo-piceous, the apical pale areas broadly confluent on 

 the suture, the combined area only very broadly and subangularly 

 sinuate anteriorly; under surface ochreous; head less than half as 

 wide as the prothorax, the antennae shorter than in the preceding, 

 the club as long as the five preceding joints, the third joint longer 

 than the next two combined; prothorax short and transverse, the 

 strongly converging sides moderately arcuate; elytra somewhat 

 longer than wide, obtusely parabolic in outline, covered throughout 

 with not very fine micro-reticulation, which also is not disposed in 

 distinct transversely wavy lines, the punctures almost completely 

 obsolete; stria rather fine. Length 1.4 mm.; width 0.8 mm. Florida 



(Lake Poinsett). A single female floridanus Csy. 



12 Punctures of the inner series of the elytra, when visible, in the form 



of simple minute and feeble points 13 



Punctures of the two or three inner series always broadly abbreviated 

 basally and apically having the form of deep semicircular scratches; 

 color of the body testaceous throughout; hind tarsi rather long and 



slender but proportioned as usual 20 



13 Color black or piceous above 14 



Color black, with bright red elytra 18 



Color pale testaceous throughout 19

15 Form rather broadly, evenly oval, highly polished, piceous in color, 

 the elytra gradually though feebly pallescent apically; under surface 

 and legs ferruginous; head less than half as wide as the prothorax, 

 the antennae rather long, slender; prothorax distinctly more than 

 twice as wide as long, margined faintly but scarcely at all lobed at 

 base, the strongly converging sides evenly and moderately arcuate; 

 surface sometimes paler peripherally or at the sides; scutellum 

 moderate; elytra short, not distinctly longer than wide, slightly 

 more than twice as long as the prothorax, the serial punctures all 

 minute points but more distinct in the two inner series, except 

 apically and basally, somewhat as in the pusillus section but with 

 different character of the punctures; micro-reticulation somewhat
