penultimate joints of the antennae. The unique type is probably 

 a female. 



14. C. ludificans n. sp. — Elongate-oval, very convex, Wghly polished 

 and impunctate, black tliroughout, the elytra not in the least rufescent, the 

 legs black ; tibia; scarcely piceous, the tarsi flavescent ; antennae brown; pubes- 

 cence long, abundant and dark cinereous. Head distinctly wider than long, 

 transversely oval, subcircular behind, the eyes moderate and but slightly con- 

 vex ; clypeal tooth moderate in size, broad and rounded. Antennai much less 

 than y^ ^s long as the body, the club abrupt, moderately thick and almost 

 parallel ; second joint about twice as long as wide and equal to the next two, 

 the latter equal and only very slightly longer than wide ; fifth and sixth 

 subequal and nearly ^g longer than wide ; seventh much more elongate and 

 scarcely visibly thicker, cylindric, ^5 longer than wide ; eighth not distinctly 

 longer than the seventh but 3^2 thicker, oval, fully as long as wide, almost 

 similar to the ninth and tenth ; eleventh obliquely pointed, much shorter than 

 the two preceding combined. Protliorax rather small, scarcely as long as wide, 

 strongly conic, the sides slightly arcuate, becoming feebly sinuate near the 

 apex, the latter rather more than J2 ^s wide as the base, which is scarcely y^ 

 wider than the head ; surface perfectly even. Elytra elongate, gradually and 

 acutely pointed behind, fully }4 longer than wide, much more than twice 

 as long as the prothorax and very nearly twice as wide, the sides more 

 strongly arcuate behind basal third ; humeral plica and adjacent impres- 

 sion very short, feeble and inconspicuous ; two basal fovese approximate, deep 

 and distinct ; subsutural impressions almost completely obsolete, the suture 

 perfectly devoid of raised margin toward base. Legs rather long, the anterior 

 femora strongly, intermediate moderately and posterior feebly, clavate. Length 

 1.65 mm. ; width 0.7 mm. 



Iowa (Iowa Cit}'). Mr. Wickhara. 



The male type of this species ditfers frova feviorale'xn its larger 

 size, much feebler elytral impressions, relatively smaller pro- 

 thorax, larger cl3^peal tooth and in the absence of any sexual 

 modification of the anterior femora, these being as usual sparsely 

 clothed with decumbent hairs, becoming gradually subglabrous 

 toward base on the upper surface. 



In this specimen the oedeagus is fully exposed, and the chitinous 

 copulatory organ appears to be of the usual type ; it is wide, 

 nearly flat, rapidlj'^ narrowed in ogive toward apex, the latter pro- 

 duced in a short acute and thickened spicule; at each side there 

 is an acute denticle bearing a long double seta ; on the under 

 surface toward base there is a thick and oval plate, attached 

 basally, with its edges thin and explanate ; the efferent duct prob- 

 ably protrudes between these plates. In some species it may be 

 noted that the acute apical spicule becomes wider, and sometimes 

 transversely truncate at tip.
