Elytra with impressed and feebly punctate sulci, the intervals smooth and 

 alternately wider and more elevated especially toward base ; pronotura 



with coarse sparse and elongate punctures graiiai'ia 



Elytra with contiguous double series of coarse deep punctures, the double 

 series separated by narrow uniseriately punctate intervals. 

 Pronotal punctures fine even and distinctly separated, the surface smooth 



and unusually convex linearis 



Pronotal punctures rather coarse, deep, very dense especially toward the 

 sides, rounded and not elongate, the surface rather depressed on the disk. 



oryzae 



Pronotal sculpture extremely coarse deep and dense, consisting of long 



sinuous anastomosing and obscurely punctate rugse, with a narrow but 



entire subcariniform median line ; elytral sculpture exceedingly deep and 



dense Mlgicollis

The differences given by Gyllenbal to distinguish 7'emofepKnctafa 

 are apparently not sufficient, for, color being of little or no value, 

 the only character given to distinguish it is the slightly greater 

 distinctness of the strial punctures toward the suture and of the 

 punctured series of the sutural interval. Length 3.3-4.0 nnn. ; 

 width 1.1-1.3 mm. 



Distributed throughout the United States. 



C. linearis Hbst.— Kaf., VII, p. .5, t. 100, f. 1. 



Described from the West Indies but occurring at times in the 

 Atlantic States. It may always be known by the fine even punc- 

 tuation of the pronotum. Length 3..3-3.8 mm. ; width 1.1-1.15 mm. 



Probably a native of India, from which region a variety is noted 

 in the Munich Catalogue. 



C. oryzae Linn. — Amoen. Ac, VI, 1763, p. 395. 



The typical form of this cosmopolitan species is perhaps the 

 smallest member of the genus. It somewhat resembles the two 

 previous species in outline, but is very densely punctured on the 

 pronotum, the punctures much coarser than in linearis and not 

 elongated as in granaria. A series of eleven specimens of what 

 may be regarded as the typical form, give the length 2.1-2.8 mm. 

 and width 0.75-1.0 mm. 



Var. zea-mais Mots.— Etud. Ent., IV, 1855, p. 77. 



Similar in every appreciable detail of structure to oryzae, but 

 always larger and especially stouter. A series of eight specimens
