the strides rather finer; antennae rufo-ferruginous; prothorax al- 

 most perfectly similar, except that the small foveolae near the base, 

 though similar in position and extent, are feebler; elytra almost 

 similar in every way, but with the striation extremely fine and the 

 intervals flat even in the male. Length (cf 9 ) 7-9-8.Q mm.; width 

 3.65-3.9 mm. Mexico (Federal District) to Arizona (Tugson). 

 Very abundant mexicana Dej. 



Form rather narrower and more depressed than in either of the preceding, 

 smaller in size and with relatively somewhat smaller head and much 

 shorter prothorax, black, with very faint bronze lustre above, the 

 legs obscure rufous, the femora blackish and submetallic; head but 

 little over half as wide as the prothorax, with prominent eyes and 

 short fine and very oblique strioles; antennae short, piceous-black, the 

 two basal joints obscure rufous; prothorax fully three-fourths wider 

 than long; apex evenly but not deeply sinuate, the angles blunt; 

 sides feebly converging, finely reflexed and feebly, subevenly arcu- 

 ate from very near the basal angles to the apex; surface puncture- 

 less and with subobsolete transverse impressions, distinctly depressed 

 postero-laterally, the stria short and fine, the inner of the subbasal 

 foveoles short, deep, linear, the outer faintly impressed, oval and 

 subobsolete; elytra rather less than one-half longer than wide, at 

 the middle barely perceptibly wider than the prothorax, obtusely 

 ogival behind; stria? fine, punctureless, the scutellar moderate, .free; 

 lateral series moderately though abruptly interrupted; intervals 

 nearly flat, alutaceous. Length (9) 7-8 mm.; width 3.3 mm.

3 Body still smaller, rather convex, subparallel, shining, with faint 

 greenish-bronze lustre, the under surface and legs dark rufous; ely- 

 tra (9) alutaceous, strongly micro-reticulate; head slightly more 

 than half as wide as the prothorax, with prominent eyes and very 

 small punctiform strioles; antennae short, pale piceo-ferruginous, 

 the three basal joints paler, rufous; prothorax two-thirds wider than 

 long; apex very moderately sinuate, much narrower than the base 

 and with broadly obtuse angles; sides subevenly and moderately 

 arcuate, sharply though narrowly reflexed, becoming subparallel be- 

 hind about the middle; surface punctureless, not distinctly depressed 

 postero-laterally, the transverse impressions obsolete, the stria very 

 fine, abbreviated; inner of the subbasal foveoles short, fine and lin- 

 ear, the outer oblique, short and feebly impressed; elytra not quite 

 one-half longer than wide, barely perceptibly wider than the pro- 

 thorax, obtusely ogival behind, the sinus feeble; striae fine but rather 

 groove-like, impunctate, the scutellar short; lateral series more 

 widely separated medially but not interrupted; intervals wide, al- 

 most perfectly flat throughout. Length (9) 7-5 mm.; width 3.25 

 mm. Mexico (Salazar, Mex.), Wickham *habilis n. sp. 



Body more abbreviated, rather convex, bronzed above, the under surface 

 and legs dark rufous; elytra alutaceous in the female; head larger 

 than in the preceding, fully three-fifths as wide as the prothorax; 

 eyes prominent; strioles short, fine and oblique; antennae not extend- 

 ing to the thoracic base, piceous, the two basal joints rufous; pro-
