22 MEMOIRS ON THE COLEOPTERA 



though no denser than laterally; scutellum similar; elytra nearly 

 one-half longer than wide, sculptured nearly as in the preceding, 

 the pubescence largely denuded in the type, the apex subevenly 

 and rather strongly rounded. Length 9.6 mm.; width 5.65 mm. 



New Hampshire neglectus n. subsp. 



B Very similar in general form and size to americanus but smoother, 

 more piceous in color, the short black vestiture of the pronotum 

 mingled with fulvous and not silvery hairs, the vestiture of the 

 elytra shorter, with similar scattered silvery hairs, especially 

 on the alternate intervals behind the black condensations, but with 

 the space enclosed by the transverse irregular silvery lines contain- 

 ing fulvous and not black hairs, these fulvous hairs forming rather 

 solid blotches; under surface castaneous-brown, the fine asperities 

 of the abdomen sparser than in americanus. Length 8.6 mm.; 

 width 5.1 mm. Manitoba (Aweme), Criddle. 



manitobae n. subsp. 



Body blackish-brown in color, paler rufo-piceous beneath, the legs nearly 

 black, the tarsi but slightly paler; form more elongate and parallel 

 than in the two preceding species; head nearly as in neglectus through- 

 out; prothorax also nearly similar, but little less than one-half as 

 long as the basal width, the converging sides becoming feebly sinu- 

 ate near basal third and not nearly straight throughout as they are 

 in neglectus; punctures very fine and close-set, the pubescence short, 

 closely decumbent, not dense, black and but feebly variegated; 

 scutellum densely nigro-pubescent; elytra nearly one-half longer 

 than wide, the sides parallel and straight to well behind the middle, 

 then gradually rounding and converging to the moderately obtuse 

 tip; pubescence blackish but not dense, not concealing the finely, 

 densely chagrined and punctulate surface, except in the denser 

 longitudinal patches of the alternate intervals, the transverse silvery 

 bands as in americanus; metasternum densely rugose laterally, 

 'closely but clearly, asperately punctate medially, the punctures 

 becoming much finer and still closer medially behind, the median 

 line very finely subimpressed, crossed just behind the middle by a 

 short impressed transverse fossa. Length 8.8 mm.; width 5.0 mm. 



Labrador (West St. Modest) imperitus n. sp. 



Body having almost exactly the same rather narrow subparallel form of 

 imberitus, differing in having the head very much smaller in size, the 

 prothorax shorter, distinctly more than twice as wide as long, with 

 the vestiture not quite so short and much less uniform, being varie- 

 gated by an intricate pattern of pale lines; elytra nearly similar; 

 metasternum not so shining and not having distinctly defined punc- 

 tures anteriorly but with coarser confluent imbriform rugulation 

 in subtransverse wavy lines; abdomen with the very fine and well 

 separated asperities still finer, the hairs arising therefrom finer, more 

 obscure and much less visible. Length 8.0 mm.; width 4.8 mm. 



Manitoba (Aweme), Criddle angustulus n. sp. 



8 Mesosternal emargination much deeper, its sides becoming almost 

 parallel anteriorly, generally somewhat narrower. Moderately 

 small in size, elongate-oval, black throughout, the legs scarcely,
