and more widely separated; pygidium much more shining, blackish 

 to pallid, convex, the arcuate scratches shorter, much sparser and 

 very much stronger, sometimes punctiform; tarsal claws somewhat 

 as in undulata. Length (cf 9 ) 7-8-9.5 mm.; width 4.0-4.9 mm. 

 North Carolina and Kentucky to Florida (Lake Worth). Very 



abundant nigropicta n. sp. 



A Similar but rather smaller and more slender, very convex, shining, 

 similarly colored, except that the black maculation of the elytra 

 is much more developed and confluent, both transversely and 

 longitudinally, frequently showing the pale ground color only 

 as small detached dashes and spots; head similar, the trapezoidal 

 clypeus not quite so abbreviated; prothorax similar but less elongate 

 and relatively smaller, nearly twice as wide as long (9 ), smaller, 

 less transverse and more conical (cf); elytra nearly similar; 

 pygidium with the sculpture less strong and more closely confluent; 

 antennal club longer in the male but shorter in the female, in the 

 latter barely as long as the preceding five joints. Length (cf 9 ) 

 S.omm.; width 4.4-4.7 mm. Canada (Ontario). Two examples. 



canadensis n. subsp. 



B Nearly similar but shorter and more reddish in color; the rufous 

 head has the clypeus smaller and shorter than in the preceding 

 and is more nearly semi-elliptical as in undulata; prothorax as in 

 nigropicta but with the small punctures still more remote discally 

 though much more close-set near the sides; they are everywhere 

 a little stronger but not at all as in undulata; elytra only a fifth 

 longer than wide, the regular series of very moderate punctures 

 not impressed, the much smaller confused punctures of the second 

 interval much smaller; pygidium shining, the irregular confluent 

 wavy lines rather strong, much closer than in nigropicta and more 

 closely resembling those of undulata, but coarser and with much 

 more shining surface; inner claw of the anterior tarsi (9 ) slender, 

 strongly and evenly arcuate, bifid in only apical fourth or fifth, 

 the upper ramus distinctly more slender than the lower and not 

 quite so long. Length (9) 8.4 mm.; width 4.5 mm. Florida 



(Key Largo). One specimen floridana n. subsp. 



C Form nearly as in undulata but larger and stouter, similar in 

 coloration, except that, as in the case of nigropicta and allied forms, 

 no example having the detached anterior thoracic area so fre- 

 quently seen in undulata, are at hand, all being black, with pale side 

 margins; clypeus relatively large, trapezoidal, with rounded angles; 

 antennal club (cf) nearly as long as the stem, or ( 9 ) three-fourths 

 as long; prothorax as in nigropicta, less abbreviated, smoother and 

 more finely and less conspicuously punctate than in undulata; 

 scutellum generally pale, sparsely punctate; elytra but little 

 longer than wide, more inflated near the middle than in any of 

 the preceding, the black maculation of the two fasciae in detached 

 spots nearly as in nigropicta, the striae of rather small deep punc- 

 tures wholly unimpressed, the confused punctures of the second 

 interval rather small and well separated; pygidium nearly as in
