32 MEMOIRS ON THE COLEOPTERA 



and the trochanters, testaceous; head four-fifths as wide as the pro- 

 thorax, though much narrower than an elytron, the sulci rather 

 deep, moderately wide; antennae black, slender, three-fourths as 

 long as the elytra, the medial joints nearly three times as long as 

 wide; prothorax one-half wider than long, the sides strongly, evenly 

 rounded to near basal fourth, straight and parallel thence to the 

 right and very sharp angles, the apical slightly blunt, the sides 

 strongly reflexed; stria deep but visible only between the very faint 

 transverse impressions; foveae very large, shallow and rugulose, 

 briefly linearly somewhat deeper centrally, the carina long and dis- 

 tinct; elytra nearly one-half longer than wide, three-fourths wider 

 than the prothorax, strongly rounded behind in two-fifths, the sides 

 broadly and moderately arcuate; striae fine but impressed and dis- 

 tijict throughout the width, shallower laterally, the seventh obso- 

 lete, all faintly and irregularly micro-subpunctulate, the foveae at 

 two-fifths and three-fourths. Length (9) 4.0-4.6 mm.; width 1.9 

 mm. Colorado (Boulder Co.), Mrs. T. L. Casey., .turbatum n. sp. 



Black, much more faintly virescent anteriorly, the elytra much paler 

 testaceous-brown throughout, black and non-metallic beneath, the 

 epipleura piceous; legs blackish-piceous, the trochanters pale; head 

 three-fourths as wide as the prothorax, very much narrower than an 

 elytron, the sulci very wide, the intervening convexity of the front 

 narrower and stronger; antennae black or feebly picescent, four-fifths 

 as long as the elytra, the medial joints fully three times as long as 

 wide; prothorax shorter, three-fifths wider than long, only feebly 

 rounded at the sides anteriorly, the sides moderately oblique and 

 broadly, feebly sinuate in about basal half, becoming parallel only 

 at the right basal angles, the apical angles obtuse and blunt; surface 

 nearly as in turbatum but with rather more pronounced and more 

 rugulose transverse impressions; elytra shorter and more obtusely 

 rounded in about apical third, two-fifths longer than wide, three- 

 fourths wider than the prothorax; striae deeply impressed inwardly, 

 very fine and feeble outwardly, the seventh obsolete; foveae at two- 

 fifths and rather before three-purths. Length (cf ) 4.0 mm.; width 

 1.65 mm. Colorado (Red Cliff), Wickham conflictum n. sp. 



35 Seventh stria distinct. Body rather depressed, ventricose, shining, 

 the head not duller, black, with metallic-greenish lustre, the elytra 

 polished, castaneus and not metallic; under surface black; head 

 three-fourths as wide as the prothorax, much narrower than an ely- 

 tron, the sulci deep, alutaceous; antennae slender, about as long as 

 the elytra, the medial joints fully three times as long as wide; pro- 

 thorax slightly more than one-half wider than long, the sides broadly 

 rounded and rather widely reflexed, becoming moderately oblique and 

 broadly, feebly sinuate in about basal half, the angles right and very 

 sharp, the apical blunt; surface with the stria deep, ending at the 

 obsolescent impressions, the foveae very large, shallow and rugose, 

 briefly and linearly somewhat deeper centrally, the carina strong in 

 basal fourth; elytra oblong, parallel, with broadly arcuate sides and 

 rather obtusely rounded apex, two-fifths longer than wide and three- 

 fifths wider than the prothorax, the striae very distinct, smooth
