3O2 MEMOIRS ON THE COLEOPTERA 



prothorax (cf 1 ) not quite as long as wide, the parallel sides very 

 evenly and rather strongly arcuate throughout, the dense fine 

 punctures and dull surface nearly similar, the hairs short, even 

 and sparse, with a small irregular dense sublateral cluster just 

 before the middle and at base; scutellum much smaller, less than 

 a third as wide as an elytron; punctures similar but tending more 

 to lineal arrangement; fifth ventral rounded at tip as in the 

 preceding. Length (cT) 12.5 mm.; width 2.8 mm. Texas. 



scuticularis n. subsp. 



Prothorax larger, inflated, distinctly wider than long, scarcely so wide 

 at apex as at base, with the sides strongly rounding medially, sub- 

 constricted at apex. Body rather stouter, the elytra cuneiform, 

 pale red-brown throughout; head densely and strongly punctate, 

 the antennae a little longer than the body, rather rapidly stouter 

 basally, the spines very short and stout, the subbasal joints very 

 coarsely, confluently punctured; prothorax (c?) very finely, densely 

 punctate and dull, with a narrow spot behind the centre, which is 

 coarsely punctate, also with two very fine blackish sublateral lines 

 at each side in basal half, which are coarsely sculptured; scutellum 

 as in villosus; elytra two and two-thirds times as long as wide, about 

 two-fifths wider than the prothorax, the decumbent pubescence 

 rather long, coarse and abundant, the condensed patches larger than 

 in the preceding forms, the punctures coarse and close basally, 

 becoming very fine and sparse distally, the apices as in villosus; fifth 

 ventral broadly rounded. Length (cf) 13.8 mm.; width 3.4 mm. 



Wisconsin lacustris n. sp. 



7 Male with the thoracic punctures small and very close but not con- 

 tiguous, the fine interspaces shining, the smooth median line entire, 

 dilated behind the middle, fine anteriorly, bordered throughout its 

 length by coarse punctures, the sparse pubescence forming an elon- 

 gate sublateral condensed spot anteriorly and another in same line 

 at base, with a narrow smooth line having a few coarse punctures 

 connecting the two. Body very slender, parallel, blackish, the 

 elytra, legs and antenna? dark brown, the latter slender, not quite 

 as long as the body, the third joint much shorter than the first, 

 not longer than the fourth, the spines small, finely punctured; pro- 

 thorax as long as wide; scutellum rather small; elytra just visibly 

 tapering from the base, more than three times as long as wide, two- 

 fifths wider than the prothorax, the condensed patches loose and 

 indefinite; punctures coarse, deep, close, separated by their own 

 diameters, smaller though still rather strong distally; fifth ventral 

 broadly, evenly arcuate. Length (cf) 12.5 mm.; width 2.6 mm. 



Levette Cabinet, unlabeled medialis n. sp. 



A Parallel, the elytra not evidently tapering, similar in general char- 

 acters to medialis, except that the equally slender antennae have 

 the third joint slightly longer than the fourth though distinctly 

 shorter than the first; prothorax ( 9 ) fully as long as wide, parallel, 

 the sides evenly and moderately arcuate, the surface coarsely, 

 deeply and contiguously punctate throughout and evenly, sparsely 

 and feebly pubescent, with a small smooth spot behind the centre;
