34 MEMOIRS ON THE COLEOPTERA 



fioridana. Male with the inner anterior claw rather less deeply 

 cleft than in undulata but otherwise nearly similar; female with 

 this claw shorter, less slender and much less arcuate than in 

 floridana, with the apical cleft deeper, though much smaller, less 

 deep and more symmetrical than in the male, as usual in the 

 undulata section; sterna subglabrous as in the latter. Length 

 (cf 9 ) 8.0-8.5 mm.; width 4.6-4.8 mm. Indiana to Kansas. Six 



specimens saginatula n. subsp. 



20 Body very small in size, shining, piceous-black, sometimes deep 

 black, the elytra occasionally with faint indefinite paler shading 

 and the pronotum rarely pale at the sides and medially at base; 

 head and pronotum with very feeble metallic lustre; head rufescent 

 except basally, densely punctato-rugose, especially toward the 

 median parts of the front, sparsely punctate basally; clypeus moder- 

 ately reflexed, the outline subtrapezoidal, with broadly rounded 

 angle, to semi-elliptic, the latter more especially in the male; eyes 

 very moderate; antennal club (cf ) nearly as long as the stem, shorter 

 ( 9 ) ; prothorax nearly twice as wide as long in the latter, narrower 

 and more conical in the male and with less rounded sides, these being 

 strongly rounded in the female; the general form and strong and 

 only moderately sparse punctures are as in undulata; scutellum 

 sparsely punctured, less strongly than the pronotum; elytra coarsely, 

 rather deeply, regularly striate, the striae coarsely punctured, the 

 second interval with strong, broadly confused, subrugose punctua- 

 tion; disk occasionally with a small pallid point at the middle, near 

 inner third, and a larger one externally before the middle, and also 

 with the apical margin pallid, thus indicating that the intensely 

 black coloration may only be an extreme development of the fasciate 

 ornamentation of undulata; pygidium piceous to pallid, with rather 

 strong wavy anastomosing sculpture. Male with the larger anterior 

 claw almost exactly as in undulata, the female, however, with the 

 claw almost as in the male, the lower lobe a little thinner, that sex 

 more readily distinguishable by the size of the antennal club, broader, 

 more rounded prothorax and by the thinner and less sinuous apical 

 beading of the last abdominal segment. Length (cf 9 ) 6.6-7.9 rnm. ; 

 width 3.7-4.3 mm. Pennsylvania to Florida and westward to 

 Nebraska. Twenty examples. [Anomala undulata dubia Blatch.] 



innuba Fabr. 



A Similar in general characters but more elongate, pale and uniform 

 piceous-brown in color throughout, the head and pronotum slightly 

 more rufous and with very faint metallic lustre; head similar, the 

 clypeus more than twice as wide as long, trapezoidal, with broadly 

 rounded angles and feebly arcuate apex; antennal club (cf) 

 distinctly shorter than the stem; prothorax as in the male of innuba 

 but shorter, twice as wide as long and about a third as long as the 

 elytra; in innuba it is always much more than a third as long as the 

 elytra; punctures a little smaller, sparser and less conspicuous; 

 basal bead similarly very fine as in undulata, entire; elytra as in 

 innuba but sensibly more elongate, a third longer than wide, 

 similarly sculptured and rugulose, the second interval with some
