238 MEMOIRS ON THE COLEOPTERA 



long as wide and a little longer than the preceding; prothorax not 

 very short, only slightly more than twice as wide as long, finely 

 but deeply, sparsely and very unevenly punctate, the apical teeth 

 acute, the sides of the apex prominent and oblique before them, the 

 middle teeth very slender but not long, the base broadly rounded 

 medially; scutellum very broadly obtuse; elytra about a fourth wider 

 than the prothorax, subparallel, very obtusely rounded at apex, only 

 one-half longer than wide, finely, sparsely punctate throughout, not 

 at all rugose, the two inner raised lines rather strong; metasternum 

 very finely but closely punctulate toward the sides; tarsi more slender 

 than usual, the canaliculation very fine but entire and similar on the 

 middle and posterior soles. Length ( 9 ) 40.0 mm.; width 16.2 mm.; 

 length of prothorax 6.4 mm.; width of head 7.8 mm. Colorado, 

 Levette (locality unrecorded) solidus n. sp. 



II Antennae (c?) but moderately and very gradually enlarged toward 

 base, the joints not or scarcely at all sinuate beneath at tip; elytra! 

 punctures rather large and sparse but deep and perforate, not im- 

 pressed. Atlantic regions 12 



Antennae (cf) very stout toward base, with the joints deeply sinuate 

 beneath at their apices; elytral punctures not so coarse as a rule 

 and always impressed, not perforate 13 



12 Form much elongated, shining, piceous to tawny-yellow, the head 

 and, to a less degree, the prothorax, darker; head very moderate 

 or rather small in size, much narrower at the tempora than across 

 the eyes, which are larger and more convex than in any other species 

 and with an unusually small emargination, separated by barely 

 one-half their width in both sexes; antennae (cf ) extending to apical 

 fifth of the elytra, the anastomosing lines unusually strong, the 

 last joint obliquely truncate beneath at base, or ( 9 ) slender, ex- 

 tending to the middle of the elytra, with the last joint much shorter 

 and narrower than the preceding; prothorax very transverse, mod- 

 erately bisinuate at base, rather prominent but broadly rounded at 

 the sides of the transverse apex, thence obliquely rounded to the apex 

 of the acute anterior teeth, the middle tooth short, acute, hamate, 

 much nearer the anterior than in any other species, the hind angles 

 right, blunt, not at all prominent; surface with numerous small but 

 strong punctures; scutellum moderate, more or less angulate; elytra 

 long, very nearly twice as long as wide, about a fourth wider than 

 the prothorax, obtuse at tip, subparallel, with broadly arcuate sides, 

 the raised lines subobsolete; metasternum throughout with rather 

 long dense pubescence (cf ), or finely and closely punctulate, with 

 short inconspicuous pubescence, becoming obsolete medially (9); 

 tarsi (9) slender, the groove becoming obsolete on the third joint 

 of the posterior and visible only toward base of the first joint of the 

 intermediate. Length (cf) 27.0-29.0, (9) 36.5-42.0 mm.; width 

 (cf) 10.6-11.0, (9) 14.0-16.5 mm.; extreme length and width of 

 prothorax (9) 5.8X13.4 mm. Middle Atlantic states to Florida, 

 also Indiana. Abundant. [P. pocularis Dalman, Sch., Syn. Ins.,
