club moderate, sparsely pubescent and shining toward base. Prothorax very 

 nearly as long as wide, the sides parallel and broadly arcuate to apical fifth, 

 then more strongly rounded, thence strongly convergent and distinctly sinuate 

 to the apex, wliich is about three-fifths as wide as the base, the latter trans- 

 verse and very broadly, evenly and feebly bisinuate, the median lobe not 

 prominent ; disk rather coarsely, not very densely, unevenly punctate, the 

 impunctate line visible behind the middle, the punctures unequal in size, un- 

 evenly distributed and often sliglitly elongate. Scutellum very small , wider 

 than long. Elytra but slightly wider than the prothorax and three-fifths 

 longer, the sides rather strongly convergent and broadly feebly arcuate, the 

 apex evenly, not broadly rounded ; humeri not prominent ; strife very coarse, 

 deep ; intervals just noticeably wider than the grooves, each with a single 

 series of coarse, deep, close-set punctures, uneven in size, often slightly elon- 

 gate and frequently anastomosing. Abdomen strongly but not very coarsely or 

 densely punctate. Prosterfium flat, separating the coxfe by a little more than 

 their own width. Length 2.8 mm. ; width 1.15 mm.

The single specimen appears to be a male, and the species some- 

 what resembles deplanata, differing in its distinctly narrower form, 

 much smaller pronotal punctures and longer, more conspicuous dorsal 

 vestiture, as well as the characters given in the table. 



5 Liilinobaris deplanata n. sp. — Oblong, depressed above, moder- 

 ately shining, brownish-black throughout, subglabrous, the squamules small 

 narrow and very sparsely, almost uniformly distributed above and beneath. 

 Head minutely punctate anteriorly, alutaceous and impunctate in basal half, 

 the transverse impression strong, broadly angulate in profile ; beak with a few 

 bristling squamules at base, rather slender, cylindrical, evenly, somewhat 

 feebly arcuate, coarsely lineato-pnnctate, more densely so at the sides toward 

 base, equal in length to the prothorax, the antennje inserted distinctly beyond 

 the middle, the basal joint of the funicle subequal to the next three, second 

 one-half as long as the first, not quite equal to the next two, club abrupt, 

 rather robust, scarcely as long as the preceding five joints combined, densely 

 pubescent, the basal joint constituting a little more than one-half the mass 

 and more sparsely pubescent very near the base. Prothorax almost as long as 

 wide, the sides broadly, evenly arcuate and convergent anteriorly, becoming 

 straight and parallel in basal half, subapical constriction feeble ; apex one- 

 half as wide as the base, the median lobe of the latter broadly rounded and 

 feeble; disk coarsely, deeply, somewhat unevenly punctate, the punctures 

 -slightly elongate-oval and distinctly separated ; impunctate line incomplete. 

 -Scutellum small, glabrous, subquadrate, widest behind. Elytra but very

 the apex narrowly subtruncate ; humeri not prominent ; disk rather coarsely
