Elytral punctures very remote, the surface almost glabrous but squamose 

 at the base, behind the scutellum and obliquely at the sides behind the 

 middle ; intervals extremely unequal in width, the strise finer and not 

 noticeably punctate 1 grandicollis 



Elytral punctures closer and larger, more confused, the strise much coarser, 

 deep, distinctly punctate at the bottom ; vestiture more abundant, densely 

 squamose also in a sutural line behind the middle ; intervals much less 



unequal in width ; size somewhat larger 2 iusignis 



Pronotal punctures very coarse and not dense, with merely an elongate and 

 ill-defined median area, toward which they become still sparser; elytra 

 with an abbreviated post-scutellar spot which is covered with large white 

 scales 3 obsoletus 



Calandriiuis appears to be peculiar to the somewhat isolated 

 zoological province embracing Colorado and the northern part of 

 New Mexico.

Oblong-oval, strongly convex, polished, piceous-black, the beak, 

 antenna? and legs paler, rufous ; integuments sparsely and unevenly 

 squamose, the scales yellowish-white, long, slender and sparse on 

 the pronotum, denser and larger toward the sides, there becoming 

 whiter and broader toward base ; on the elytra they are extremely 

 sparse, long and very slender, becoming larger, dense and whiter 

 toward base, behind the scutellum and in a small oblique spot be- 

 hind the middle, from the third stria to the sides ; most conspicuous 

 beneath on the prosternum, elsew^here long, fine and sparse. Beak 

 slender, cylindrical, evenly, moderately arcuate, as long as the head 

 and prothorax, the basal joint of the antennal funicle fully as long 

 as the next three, the second as long as the following two ; club 

 rather small, narrowly oval, pointed. Prothorax nearly as long as 

 wide, the sides very feebly divergent and slight!}^ arcuate from the 

 base nearly to apical third, then broadly rounded, the constriction 

 large and distinct; apex nearly three-fourths as wide as the base; 

 disk coarsely, deeply and closely punctate, the impunctate line wide, 

 fusiform, abruptly limited, smooth and polished, extending to the 

 impunctate apical margin. Scutellum very small, deeph^ seated. 

 Elytra oviform, narrowly rounded at apex, quite distinctly wider and 

 scarcely more than one-half longer than the prothorax, but distinctly 

 longer than wide, strongly arcuate at the sides near the base, the 

 humeral callus not evident ; stria? abrupt, deep, moderately fine, the 

 intervals flat, extremely unequal in width, the third as wide as the
