1913] Wickham — New North American Elateridce and Searaboeidee 29 



not occurring in any other North American species in that division 

 of the genus. It is of special interest on account of its relation to 

 this small assemblage of rare forms with explanate pronotal sides. 



Aphodius columbiensis sp. nov. 



Form rather stout, strongly convex, broader posteriorly, blackish-piceous, 

 opaque, legs reddish-piceous, antennas testaceous, club sooty. Head without tuber- 

 cles, finely and sharply but not closely punctured, clypeus emarginate at middle, 

 angles distinct but rounded, sides diverging regularly with scarcely any arcuation to 

 the rounded, moderately prominent genae, margin feebly reflexcd, clypeal punctua- 

 tion fine and rather sparse. Prothorax with the sides parallel posteriorly, arcuate 

 for a short distance anteriorly, all the angles rounded, surface alutaceous and having 

 besides a double system of punctuation, the larger punctures fairly evenly disposed 

 (but allowing some smoother areas in the discal region and an impunctate median 

 line) and ordinarily separated by approximately their own diameters, the fine punc- 

 tures irregularly scattered among the others. Basal marginal line distinct. Elytra 

 at base a little narrower than the prothorax, becoming broader behind the middle, 

 humeri dentiform, disk very regularly but finely striate, the striae with well-marked 

 distant punctures giving a catenate appearance to the grooves, interspaces flat, 

 strongly alutaceous and opaque but impunctate. Body beneath rather coarsely 

 and sparsely punctate on the meso and metasternal side-pieces, the mesosternum 

 not carinate, abdominal punctuation indistinct, replaced by a longitudinal rugosity 

 of the segments. Posterior and middle femora strongly but not densely punctate. 

 Length, 5.25 mm. 



Collected at Vernon, B. C, by Mr. E. P. Venables, who gave 

 me the type specimen. 



This also is a genuine Aphodius, belonging to Horn's group H, 

 in which it approaches A. opacus Lee, but is at once distinguishable 

 by the elytral striae being distinctly punctured. The fore tibiae 

 are strongly tridentate, crenulate above the upper tooth, the edges 

 fimbriate with yellow hairs. Both spurs of the middle tibiae are 

 sharply pointed at their apices and of normal form, differing only 

 in size, those of the hind tibiae are very long, slender and sharp. 

 The basal joint of the hind tarsus is about as long as the next three. 

 The alutaceous sculpture appears to extend to all parts of the body, 

 even showing on the legs. 



Anomala camancha sp. nov. 



Size large. Surface subopaque. Form subparallel, recalling Cyclocephala. 

 Color yellowish testaceous, head, tibiae, and tarsi darker, reflexcd edge of clypeus, 

 prothoracic marginal bead, outer edging of fore tibia', and most of the spines and 

 ridges on the middle and bind pairs piceous or blackish in somewhat varying degree,
