90 MEMOIRS ON THE COLEOPTERA 



A Similar to lanigera but much larger and generally of somewhat 

 darker luteo-flavate coloration above, the pubescence beneath 

 nearly similar; clypeus rather less transverse; prothorax similar 

 but not quite so abbreviated; scutellum not so transverse; elytra 

 nearly as in lanigera but with the three or four medio-discal lines 

 of punctures less definite or replaced by two more or less distinct 

 geminate series, somewhat as in subcribrata. Length (cf 9 ) 21.5- 

 24.5 mm.; width 12.5-15.0 mm. Indiana, Iowa and Wisconsin. 



Eleven examples obesa n. subsp. 



5 Form oblong, the female more oval, convex, shining, pale flavate- 

 brown in color above, the anterior parts with but very feeble metallic 

 glint, the under surface and legs nearly as in lanigera, except that 

 the tarsi are black or nearly so, with the usual metallic lustre, the 

 pubescence nearly similar; bead (cf ) very small, barely two-fifths 

 as wide as the prothorax, or ( 9 ) nearly half as wide as the latter, 

 the clypeus twice as wide as long or a little less, the apex arcuato- 

 truncate and reflexed, with moderately rounded angles, the surface 

 rather strongly but loosely punctate; prothorax not qiute twice as 

 wide as long, widest behind the middle, the apex moderately sinuate, 

 with short rounded angles, the basal angles narrowly rounded ; surface 

 nearly as in lanigera; scutellum more narrowly ogival; elytra (cf ) 

 barely at all longer than wide, parallel, with broadly arcuate sides, 

 broadly, obtusely rounded at apex, the lateral impression as in 

 lanigera, but the longitudinal impression thence posteriorly is barely 

 traceable, the punctures fine and sparse, the median part of each 

 elytron having two very feebly defined geminate series, or ( 9 ) 

 distinctly longer than wide, oval, much less obtuse at apex and with 

 the sides obtusely prominent near basal third; pygidium in both 

 sexes differing decidedly in being minutely and densely rugulose and 

 alutaceous throughout. Length (cf) 18.6-19.6, (9) 20.5 mm.; 

 width (cf) 11.0-11.5, (9) 12.2 mm. Louisiana (Vowell's Mill). 



molaris n. sp. 



Form very broadly rounded, very shining and pale brown throughout 

 above, the elytra sometimes more flavate; under surface and legs 

 nearly as in lanigera; head (cf ) notably smaller, sparsely punctured 

 throughout, the clypeus browner and without lustre, arcuato- 

 truncate, with very broadly rounded angles; prothorax shorter, 

 much more than twice as wide as long, the eides more strongly 

 converging anteriorly from a point nearer the base, the basal angles 

 more rounded; surface similarly punctulate; scutellum not quite so 

 broadly ogival; elytra barely visibly longer than wide, very obtuse 

 at apex, not very much wider than the prothorax, the parallel sides 

 moderately arcuate, the lateral impressions as in lanigera; punctures 

 fine and everywhere very sparse, the punctulation of the inter- 

 spaces extremely sparse and minute; toward the middle of each, two 

 very feeble and widely separated irregular double series are more or 

 less evident; pygidium nearly as in lanigera but more convex; under 

 surface similarly colored and pubescent. Female still more rotund, 

 the elytra one-half wider than the prothorax, fully as wide as long, 

 with strongly rounded sides, which are barely visibly more prominent
