tiou, the scales being largei}^ denuded throughout the body and 

 legs, but, from the small patches remaiuing, it is certain that well 

 preserved specimens will prove to be densely squamose through- 

 out. 



C. missourianus. — Stout, elongate-suboval, black, the scales separated 

 except in the condensed areas, the latter having the scales pale in color, espec- 

 ially evident broadly along the elytral suture and unevenly tovrard base, also 

 in some small areas subtransversely arranged behind the middle, the scales 

 elsewhere on the elytra small, oval, dark in color and widely separated, the 

 scales of the pronotum large and rounded, each filling one of the coarse, deep 

 and slightly separated punctures. Head, basal parts of the beak, entire under 

 surface and legs densely clothed with whitish scales; beak finely, sparsely 

 punctured and glabrous beyond the point of antennal insertion; second joint 

 of the funicle longer than the next two combined. Prothorax subcorneal, not 

 quite as long as wide, the sides feebly convergent and nearly straight almost to 

 the apex, then a little more rounded and convergent to the apex, which is broad- 

 ly sinuato-truncate and not at all tubulate ; surface within the densely squamose 

 flanks coarsely and not very densely punctured, with a short impunctate 

 median line. Elytra short and broad, I3 longer than wide, % longer than the 

 prothorax and % wider, the humeri rather prominent; sides rapidly convergent 

 and rounded behind to the apical prolongation; striae rather coarse, the squam- 

 ules slender, broader in the areas of condensation. Length 3.8 mm.; width 

 1.75 mm. 



Missouri (St Louis). Mr. Soltau. 



This species, described above from the female, is about as large 

 as operculatus and greatly resembles it, but is stouter, with the 

 prothorax more sparsely puuctured and more conical, the sides 

 being less arcuate. The squamulation of the elj^tra is still more 

 uneven. Of operculatus I have specimens before me from Dakota, 

 Kansas and Iowa. 



C. sparsus. — Stout, oval, rather strongly convex, the body and legs deep 

 black throughout; scales pure white, oval, rather sparse except in a sublateral 

 pronotal vitta and in some small nubilate condensed spots disposed in the 

 usual two posteriorly arcuate series on the elytra; scales of the pronotum 

 moderately large, broadly rounded, each filling one of the large separated 

 punctures, those of the under surface not quite contiguous. Head and basal 

 parts of the beak rather densely squamose, the eyes separated at lower third by 

 about }£ of their own width; beak finely punctulate, black, polished and 

 glabrous beyond the point of antennal insertion. Prothorax % wider than 

 long, the sides subparallel, distinctly but somewhat unevenly arcuate, oblique 

 and feebly sinuate at the apex, the latter broadly sinuate and not at all tubu- 

 late; punctures coarse and deep. Elytra short, }^ longer than wide, nearly 

 twice as long as the prothorax and }^ wider, the sides quite arcuate; humeri 

 not at all exposed at base, the humeral callus moderately prominent; pos-
