no other evidences of immaturity than the very uniform pale color- 

 ation. Ten specimens texanum Chd. 



Form elongate and convex but less ventricose, the prothorax much more 

 transverse; head larger and scarcely at all narrower than an elytron, 

 with more prominent eyes, fully three-fourths as wide as the pro- 

 thorax, which is one-half wider than long, with strongly rounded 

 sides, becoming rapidly parallel only very near the angles, which 

 are right and sharp; surface nearly similar, except that the very deep 

 linear foveae are more distant from the fine carina; elytra barely 

 more than one-half longer than wide and scarcely more than a third 

 wider than the prothorax, otherwise nearly as in texanum, except 

 that they are more rufescent behind and .that the elytral striae be- 

 come obsolete near apical fourth or fifth. Length (cf) 5-5 mm.; 

 width 2.2 mm. Two examples from the Levette collection, prob- 

 ably taken in Indiana cogitans n. sp. 



Form elongate, moderately convex, black, with bluish lustre, the elytra 

 not highly polished as in the preceding but apparently somewhat 

 alutaceous; legs similarly rufous; antennae long and slender; pro- 

 thorax widest near apical third, two-fifths wider than long, the 

 strongly arcuate sides sinuate just before the basal angles; stria 

 entire; foveae broadly, strongly and irregularly impressed, the carina 

 very short, not attaining the angles; elytra two-fifths wider than the 

 prothorax, much more than one-half longer than wide; striae im- 

 pressed and strongly punctate, obsolete near the tip; punctures 

 strong, rather widely separated; scutellar series having four or five 

 punctures. Length 5.5. New York (Willets Point, Long Island). 

 The type has disappeared and I have not seen it since my then 

 very small collection left my hands temporarily many years ago.

45 Color deep black, the upper surface with strong greenish lustre. 

 Surface convex, as in striola, smooth and polished; head three-fourths 

 as wide as the prothorax but distinctly narrower than an elytron, 

 the eyes moderately prominent; antennae long and slender, piceous, 

 rufous basally, the medial joints rather more than three times as 

 long as wide; prothorax two-fifths wider than long, the strongly and 

 evenly rounded sides becoming rather abruptly straight and parallel 

 in basal sixth or more, the angles right and sharp; base evidently 

 narrower than the apex; surface broadly convex, punctulate at base, 

 the transverse impressions distinct, the stria deeply impressed, not 

 entire; foveae rather large, nearly smooth, oval, very deep and ad- 

 joining the distinct carina; margins strongly reflexed basally, finely 

 apically; elytra oblong, with feebly arcuate sides and gradually 

 parabolic apex, more than one-half longer than wide, fully one-half 

 wider than the prothorax; striae rather coarse and impressed, obso- 

 lete at about apical sixth or seventh, the punctures strong, moder- 

 ately separated; seventh row of very minute punctures distinct; 

 foveae near basal and apical third. Length (cf 9 ) 5.0-5.9 mm.; 

 width 2.0-2.35 mm. California (Redwood Creek, Humboldt Co.). 

 Seven specimens optatum n. sp. 



Color in great part piceous, with shining greenish gloss 46
