CETONIHSL-E 287 



the medial prominence at the apical margin moderate, the surface 

 punctureless; elytra large, a third longer than wide, the apex broad 

 and very obtuse; side margins rarely narrowly green, generally 

 without trace of that color, the marginal bead very full; surface dull 

 throughout and without trace of punctuation, the two discal lines 

 very obtuse and feeble, obsolete basally as usual; punctures toward 

 the sides of the metasternum unusually coarse and with coarse and 

 conspicuous pale hairs, the hind femora obliquely, coarsely scratched 

 and with distinct coarse hairs; hind tarsi unusually thick, shorter 

 than the tibiae in both sexes. Length (cf 9 ) 24.0-28.5 mm.; width 

 13.0-15.8 mm. Texas. Four examples; one is labeled "Tennessee," 

 but probably in error texana n. sp. 



Body stout but more rhomboidal than in the preceding, the upper surface 

 not quite so depressed, dull but paler green almost evenly through- 

 out, the head, marginal thoracic bead and the mes-epimera bright 

 metallic green; pronotum never with an entire marginal tawny stripe 

 but generally with some remnants of it at various parts, the elytra 

 with a broad and sharply denned, orange-tawny border from the 

 base to the suture at apex, seldom anteriorly prolonged onto the 

 solid green discal area and then only briefly; pygidium uniform tes- 

 taceous, with thin metallic-green gloss, having deep scratch-like 

 transverse interlacing and not very close-set lines and short, sparse 

 and coarse but only moderately conspicuous hairs; under surface 

 bright metallic green, the abdomen testaceous, with feeble greenish 

 gloss, the legs metallic green, the hind femora sometimes slightly 

 pallescent; cephalic ridge expanded at apex but more gradually than 

 in the preceding, the clypeal process long and large, gradually ex- 

 panded from base to the broadly truncate apex, but varying to more 

 slender and parallel, never with converging sides; prothorax rela- 

 tively larger but of the usual outline, impunctate and but little 

 narrower than the elytra, the latter a fourth to two-fifths longer 

 than wide, the sides moderately converging from base to the rather 

 abruptly obtuse apex, never punctate, the sutural angles obliquely 

 dentiform; anterior tibiae sharply tridentate, the upper tooth minute 

 in the male; hind tarsi (cf ) as long as the tibiae, shorter (9 ), rather 

 stout and compressed. Length (cf 9) 22.0-28.0 mm.; width 12.2- 

 15.7 mm. Arizona (Tugson, Phoenix and other southern localities). 

 Seventeen examples arizonica n. sp. 



Body of varying outline, stout in obliqua, notably narrow in the subspecific 

 forms here described, the lateral beading of the pronotum less dilated 

 basally, the elytra always pale tawny in color, with a triangular, 

 posteriorly attenuate sutural green area 4 



4 Under surface deep polished metallic green, the abdomen testaceous 

 throughout, with feebler metallic-green glaze. Form elongate, the 

 upper surface opaque and obscure green, the sides of the pronotum 

 and sometimes a short feeble ante-scutellar streak, tawny, the elytral 

 green area occupying not quite the entire width at base, narrowing 

 with rather ragged subarcuate outline posteriorly, very fine apically: 

 head, side margin of the pronotum, legs and epimera bright polished 

 green; pygidium testaceous, with thin bright green glaze; head
