and irregularly nodulate to greater or less degree. Length ( 9 ) 9.3 

 -9.5 mm.; width 4.2 mm. Pennsylvania. Two examples. [Amara 

 splendida Hald. and incequalis Kirby] patruelis Dej. 



Pronotum never noticeably depressed externally; strial intervals smooth 

 to faintly irregular in surface 4 



4 Form oblong-oval, moderately convex, bright green in color through- 

 out above, piceous beneath, the legs black; elytra rather shining 

 though somewhat alutaceous in the female; head as in the preceding, 

 with prominent eyes, the strioles rather deep, well developed and 

 very oblique; epistoma evenly sinuate at tip; antennae slender, the 

 medial joints two and one-half times as long as wide, black, the basal 

 joint alone rufescent; prothorax nearly four-fifths wider than long; 

 apex with rather prominent though slightly blunt angles, deeply 

 sinuate and much narrower than the base, the sides subevenly and 

 moderately arcuate, becoming almost parallel basally, finely re- 

 flexed; surface very slightly less convex postero-externally, the stria 

 and impressions nearly as in the preceding; elytra fully one-hall 

 longer than wide, with very feebly, evenly arcuate sides, at the 

 middle only just visibly wider than the prothorax, the apex sub- 

 evenly, rather obtusely rounded, the sinus distinct; striae and lateral 

 series as in patruelis, the intervals nearly smooth and subequal, 

 though there is a scarcely observable alternation in convexity, nearly 

 flat as a rule; beneath wholly impunctate as usual in this section. 

 Length (9) 8.4-8.6 mm.; width 3.7-3.75 mm. Two examples. 

 Arizona (southern),- F. H. Snow lauta n. sp. 



Form somewhat stout, oblong-oval, rather convex, bronzed above, black 

 beneath, the coxae obscure rufous; elytra shining, alutaceous in the 

 female, with strong micro-reticulation; head convex, smooth, with 

 well developed but only moderately prominent eyes, the strioles 

 very small, widely separated and oblique; antennae black, the two 

 basal joints rufescent, the medial joints on the compressed side less 

 than twice as long as wide; prothorax as in lauta, almost twice as 

 wide as long; anterior lateral fovea similarly a little before posterior 

 third; side margins even more finely reflexed; elytra similar in size 

 and relative proportion, also similar in the fine striae, but different 

 in having the striae feebly impressed, the intervals consequently 

 feebly convex and, more especially, in the form of the subapical 

 sinus, which is small and moderately deep in lauta, but very much 

 broader and relatively shallower in the present species; under sur- 

 face punctureless; tarsi long. Length (9 ) 8.3 mm.; width 3.8 mm. 



Utah (Provo), Wickham formalis n. sp. 



Farm more parallel and oblong, smaller in size and less convex than in 

 either of the two preceding; lustre dull bronze above; head moder- 

 ate, just visibly more than half as wide as the prothorax, the eyes 

 very moderately convex; strioles small, fine and oblique; antennae 

 black, with the first joint pale, extending to the thoracic base, 

 shorter (9 ). the middle joints on the narrow edge between two and 

 three times as long as wide; prothorax barely visibly less than twice 

 as wide as long, in outline and surface nearly as in the preceding, 

 the outer of the postero-lateral impressions extremely shallow and
