AMERICAN COLEOPTERA. 327 



the present, hesitated to name it. I cannot find any description fittin" 

 it ill Cliaudoir, Dejean or Chevrolat nor any American species either 

 Nortii or South, to whicli reference is made in tlie Catalogue of Geni- 

 minirer and Ilarokl, with which it agrees. 



C. alternatus, n. sp.— Black, feebly shining, head and thorax with a slight 

 reddish biouzc; beneath and legs black. Head shining with slightly metallic 

 reddish bronze, impunctured and slightly wrinkled, longitudinal impressions 

 (L'oper in front; antennne and parts of moutli black. Thorax one-fourth wider 

 at base than long, at apex narrower than the length, sides moderately rounded 

 :ind slightly narrowing at base; a median broad butshallow sulcus, containin" 

 the median fine line, on each side of which is (a row of very coarse punctures 

 extenilingto the anterior margin ; basal impressions broad densely and coarselv 

 granulatejy punctured and with a few short hairs ; surface between median 

 sulcus and margin with a few large irregularly placed punctures ; lateral mar- 

 gin slightly explanate and reflexed, with coarse punctures: color of thora.x 

 reddish bronze with a tinge of green in the impressions. Elytra broadly oval, 

 depressed, black sub-opaque, strise replaced by rows of very coarse punctures, 

 interspaces moderately convex, the third, fifth and seventh more distinctly 

 elevated, surface densely and rather coarsely granulatcly punctured clothed 

 with short, inconspicuous, brownish pubescence. Body beneath black shinini;, 

 parapleuroe and abdomen sparsely punctured, the latter also sparsely pubescent. 

 Legs black, femora with a few punctures with short setaj. Length .50 inch; 

 12.5 mm. 



This species reproduces the form of nltjcr but has rather broader 

 elytra and differs from that species by so many characters that it is 

 not worth while to recapitulate them. 



One specimen is before me obtained by Dr. Lecontc, from the British 

 Museum in exchange. Collected by Mr. Bourgeau, in the Sackat- 

 chewan region. 



ANOPHTHALMUS, Sturm. 

 A. t^uis, n. sp.— Pale rufo-leslaceous, shining. Head slightly darker in 

 color, oval, and arcuately biimpressed. Thorax broader than tiie head, slightly 

 longer than broad and sinuately narrowing to hind angles which are exactly 

 rectangular; median line distinctly impressed in its entire lengtii, basal im- 

 jircssion deep; base of thora.x truncate. Elytra elongate oval, fe«»bly convex, 

 at base slightly flattened; two-thirds longer than broad, humeri obtusely 

 rounded ; surface with feeble traces of strije and three dorsal setigerous punc- 

 tures on each elytron, in or nearest to the position of the third stria. Body be- 

 neath similar in color to the ujjper surface, legs somowiiat paler. Length .18 — 

 .24 inch ; 4.6 — fi mm. 



Three specimens of this species were collected by Prof. E. D. Cope, 

 one of the most untiring explorers of the caves of our country, in 

 AVyandotte Cave in Southern Indiana. 



This species is clo.scly allied tp Maictriesi, Mot^ch (^<ni(/ulatus, Lee) 

 but differs by its more elongate and less robu.st form and less convex 

 surface. 'J'lie elytra are sm jutlier and witli very feeble traces of striai.
