to the apex, finely, feebly serrulate because of the punctuation; 

 surface evenly convex, the punctures fine and sparse, gradually 

 becoming coarse and close but arcuate and only moderately deep 

 toward the sides; scutellum long and aciculate, smooth; elytra nearly 

 as \nfulgida but more parallel and with a longer and shallower sub- 

 basal sinus; tomentose spots very small and few in number; pygidium 

 (c?) shining, umbonate below the middle, finely sculptured in wavy 

 concentric lines, with a tomentose spot at each side; abdomen with a 

 minute tomentose spot at each side of the dorsal surface of each seg- 

 ment; hind tarsi very nearly as long as the tibiae; abdomen feebly 

 impressed along the middle in the male. Length (cf) 15.8 mm.; 

 width 9.0 mm. Arizona (Huachuca Mts.) holochloris Fall 



Pronotum with a pallid lateral margin; femora pale, at least in large part; 

 clypeus more distinctly sinuate at the middle of the apex 4 



4 Inner elytral costa evident and subequal almost throughout the length. 

 Body small and narrower, elongate-rhomboidal and feebly convex, 

 bright green above and beneath, the abdomen rufescent, the femora 

 rufous throughout; pale thoracic margin very narrow, sometimes 

 incomplete, the sides of the elytra pale brownish-red; head with 

 sparse and very moderate punctures, the denser areas of the front 

 pubescent; prothorax nearly as in the preceding but with stronger 

 and deeper punctures; scutellum long, smooth, very acute at tip; 

 elytra gradually narrowed from the base to the obtuse apex, the 

 lateral sinus deep; tomentose spots more or less distinct in short 

 transverse lines behind the middle; punctures larger, closer and 

 more conspicuous than in any other species of this section, the punc- 

 tures annular, open behind and umbilicate basally, forming long 

 wavy lines posteriorly at the sides and more arcuate though irregular 

 toward the suture, everywhere umbilicate, the hairs minute and 

 sparse; pygidium having four tomentose basal spots and with coarse 

 arcuate incised lines, umbonate near the apex (cf), not umbonate, 

 more narrowly rounded at apex and with the lines more widely 

 separated (9); hind tarsi rather slender; abdomen moderately 

 impressed along the middle in the male. Length (cf 9 ) 12.0-14.6 

 mm. ; width 6.5-7.8 mm. Florida (Marion County and Palm Beach).

Inner elytral costa only evident behind the middle 5 



5 Abdomen and pygidium without trace of tomentose spots. Body 

 (9) oblong-suboval, depressed above and very dark indigo-blue 

 throughout, except the side margins and two small basal spots on the 

 pronotum, which are pale red-brown, the sides of the elytra nubil- 

 ously red-brown except basally; under surface blue-black, the legs 

 black, the femora in part rufous; head nearly as in fulg-ida, but 

 with coarser and deeper punctures, the frontal areas with densely 

 crowded punctures; prothorax more than a third wider than long, the 

 strongly converging sides from base to apex almost evenly arcuate; 

 punctures small and sparse, becoming coarse and closer laterally; 

 scutellum smooth, moderately acute at tip; elytra a fourth longer 

 than wide, but little narrowed at the broadly obtuse apex, the lateral 

 sinus deep; tomentose spots small though numerous, especially
