replaced by dark red-brown, becoming darker and greenish toward 

 the sharp line demarcating the lateral tawny stripe on both the 

 pronotum and elytra; head proportionally a little smaller; pygidium 

 similar, except that the green basal part is not sharply denned and 

 the hairs are long, very coarse and conspicuous; under surface 

 pallid excepting the middle of the sterna; anterior tibiae of the 

 female not quite as long as the tarsi, with two large teeth, the usual 

 upper tooth very minute to obsolete; hind tarsi "much less stout 

 than in ornata and not so abbreviated. Length (9) 23.0 mm.; 

 width 13.3 mm. A single example unlabeled in the Levette 



collection tibialis n. subsp. 



C Nearly similar to nitida but with the sides of the elytra straighter 

 and the apex more abruptly transverse, the entire pronotum and 

 elytra, excepting a sharply denned tawny lateral margin, deep, ob- 

 scure and very uniform velvety-green ; under surface nearly similar; 

 pygidium different in color, the basal green area prolonged 

 medially to the apex, there inclosing a small elongate pallid spot, 

 the surface deeply impressed at each side of the middle, perhaps 

 adventitiously in the type; hind tarsi very short. Length (9) 

 20.0 mm.; width 10.8 mm. Missouri (St. Louis). 



pygidialis n. subsp. 



Outline rather more oblong-oval, the elytra with partial series of fine 

 punctures; upper surface obscure green, opaque, with tawny side 

 margins as in nitida, but with the disk of the elytra seldom much 

 variegated with tawny, generally solidly green, becoming brownish 

 toward the scutellum; head well developed, more than a third as 

 wide as the prothorax, with the longitudinal ridge as in nitida, the 

 clypeal horn, however, much larger, longer than wide, parallel to 

 slightly conical, broadly truncate at apex; prothorax very nearly as 

 wide as the elytra, with the tawny margin sometimes not attaining 

 the base, the converging sides subevenly arcuate, the apical umbo 

 moderate; elytra a fourth longer than wide, the sides feebly converg- 

 ing from the base, becoming arcuate for a considerable distance from 

 the apex, which is subtruncate as usual; pygidium nearly as in 

 nitida, but with the green basal part not so abruptly defined; under 

 surface in great part more or less pallid, with feeble metallic-green 

 gloss, the anterior tibiae (c?) tridentate, or shorter and stouter (9 ), 

 with the three teeth stouter and less widely separated; hind tarsi in 

 the former long, thick and compressed, very much longer than the 

 tibiae, shorter in the female. Length (c? 1 9 ) 22.5-23.5 mm.; width 



12.5-13.0 mm. Texas longitarsis n. sp. 



A Similar to longitarsis but not quite so large and with the series of 

 punctures at each side of both of the raised lines much stronger and 

 distinct, the two included elytral lines rather strongly embossed, 

 somewhat as in the Mexican pauperula Burm.; tawny elytral 

 margins entire, the obscure opaque green discal tint not variegated, 

 the lateral pale stripe of the pronotum not or imperfectly attaining 

 the base; clypeal horn large, subquadrate or a long truncate tri- 

 angle, but never having the strut-like longitudinal ridge at base 

 as in the obliqua section; under surface and pygidium nearly as in
