DERMESTIDyE 1 83 



in the male. Extricattis Csy., is smaller and much shorter than 

 piceus; it is briefly oval and, in the darker specimens, the humeri are 

 frequently rufescent; I have examples from Pennsylvania, Missouri 

 and Mississippi (Vicksburg). Bicolor Har. (dichrous Lee.) and 

 spurcus Lee., are made synonyms of schaefferi in the Torre catalogue, 

 but I am at a loss to understand the reason for this, for spurcus is 

 plainly a synonym of cylindricornis Say; bicolor, on the other hand, 

 seems tome to be a very good species, more elongate and with more 

 closely and strongly sculptured elytra than in cylindricornis and 

 apparently differing radically from schaefferi in coloration; brunneus 

 Fald., resembles cylindricornis very much, but is narrower and has a 

 shorter prothorax as in piceus. Elongatulus is closely allied to 

 bicolor but is narrower and has stronger frontal impressions. The 

 four following are at least distinct specifically among themselves, 

 and there is no present evidence that any one of them is an im- 

 portation: 



Attagenus canadensis n. sp. Form very broadly oblong, convex and 

 strongly shining, piceous-black, the elytra sometimes rufous; legs bright 

 rufous in the female, darker in the male; head unusually small, barely a 

 third as wide as the prothorax (9), larger (cf), minutely and loosely 

 punctulate and with small sparse palish hairs, the ocellus small; antennae 

 of the usual form, pale, the club in great part black, the last joint much 

 elongated in the male; prothorax not quite twice as long as wide, with 

 converging arcuate sides and strong basal lobe; surface impressed along 

 the base except laterally, convex, minutely, not densely punctate and 

 with the pubescence in great part luteous, especially postero-externally ; 

 scutellum acutely triangular, almost glabrous; elytra two-fifths longer 

 than wide, as wide as the prothorax but not three times as long, parallel, 

 broadly rounded at apex, very finely and rather sparsely punctured, the 

 hairs very small, fine, fuscous and inconspicuous, except toward base, 

 where they become coarser, fulvous and distinct; under surface rather 

 finely but strongly, very densely punctured throughout and with rather 

 even luteous pubescence; hind tarsi four-fifths as long as the tibiae in the 

 female. Length (c? 9 ) 3.3-4.0 mm.; width 1.7-2.2 mm. Canada 

 (Ottawa and Quebec). 



Very distinct from any other of the American species in its short 

 and broad outline, fine sparse sculpture and bicolored elytral 

 vestiture. 



Attagenus atrolucens n. sp. Elongate-oval, convex, polished and deep 

 black above, similarly black but finely, densely punctured, scarcely 

 shining and with short decumbent gray pubescence beneath, the legs 

 blackish-piceous; head (9) small, finely, densely punctate, the impres-
