NORTH AMERICAN COLEOPTERA. 21 



Male. — Unkiiow n . 



Female. — Sixth ventral segment rather acutely rounded behind. 



Length 1.3 mm. 



Detroit, Michigan ; two specimens. 



2. E. pillictatus n. sp. — Form elongated, sides nearly parallel. Pubes- 

 cence rather long, somewhat dense, semi-erect, piceo-cinereous and promi- 

 nent. Head large, slightly wider than long ; interocular surface strongly 

 and evenly convex, rather finely, very closely, and evenly punctate, jjunc- 

 tures variolate, round, and sometimes coalescent ; supra-antennal tubercula- 

 tions round and prominent ; teeth of labrum longer than breadth of intervals ; 

 antennae very slightly longer than the prothorax, joints four to seven equal, 

 third slightly longer, eighth much shorter, globular, last joint much the 

 most robust, as long as the ninth and tenth together, finely and obliquely 

 acuminate ; maxillary palpi moderate, third joint robust, very slender at 

 base, as long as the two preceding together ; terminal joint of labial palpi 

 setiform and distinct ; gula having a rounded, feebly impressed puncture 

 near the posterior limits of the buccal fissure. Prothorax widest at one-third 

 the length posteriorly, where it is just perceptibly wider than the head and 

 slightly broader than long ; sides thence rather strongly convergent poste- 

 riorly, feebly sinuate near the base ; anterior margin distinctly longer than 

 the posterior, equally arcuate ; basal angles distinct, apical slightly rounded ; 

 surface strongly convex, densely, rather finely, nearly evenly punctate, 

 punctures round ; toward the base, on each side of the middle, there is a 

 very feebly impressed, longitudinal line. Elytra at base very slightly wider 

 than the prothorax ; sides moderately divergent posteriorly, rather strongly 

 and evenly arcuate ; together broadly, roundly, and rather strongly emargi- 

 nate behind ; suture shorter than the pronotum, one-half shorter than the 

 width at base, sutural sti-iae strong, punctures round, rather small, very 

 evenly distributed and close, somewhat feebly impressed, interspaces convex, 

 nearly twice as wide as the punctures, and highly polished. Abdominal 

 segments strongly margined ; sides arcuate, first slightly wider than the 

 contiguous elytra ; surface feebly convex, impunctate, very minutely reticu- 

 lated, feebly shining. First joint of posterior tarsi one-half longer than the 

 second, very slightly shorter than the last, second joint very slightly longer 

 than the third. Prosternum rather distantly punctate, punctures impressed, 

 rather small and distinct. Length 1.6 mm. 



Crescent City, Florida; one specimen, 9. 



The color of this very distinct species is of a rather dark fuscous ; 

 antennae, oral organs, and tarsi paler and testaceous. 



3. E. floi'idae n. sp. — Form slender. Pubescence of elytra short, recum- 

 bent, rather sjjarse, fine, and inconspicuous, that of head and prothorax 

 longer, more erect, and prominent, that of abdomen still longer, piceo-cinere- 

 ous throughout. Color throughout dark reddish-testaceous. Head moderate, 

 slightly wider than long; eyes rather large, evenly convex; interocular 

 surface moderately and evenly convex, rather coarsely punctate, punctures
