somewhat exposed at base; disk evenly nigulose throughout; stria; rather nar- 

 row, deep and not distinctly punctate. Length 11.0 mm.; width 5.0 mm. 



Canada (northwest). 



Quite distinct from geminatus by the sculpture of the el^'tra, 

 and from alternans hj the equal rugosity of the elytral inter- 

 vals. The elytra are rapidly declivous behind in profile. 



Li. piiigiiis n. sp. — Obese, black and polished when denuded, densely 

 clothed with narrow pale brown scales intermixed with still narrower white 

 scales, and variegated on the elytra with small condensed spots of the brown 

 scales situated between the serial punctures; oblique sublateral vittse of tlie 

 pronotum broad, yellow and uneven ; elytra each w ith a more conspicuous 

 ochreous spot before the middle; abdomen with the sublateral yellowish spots 

 small. Head one-half as wide as the i>rothorax, densely squamose, the eyes 

 separated by about twice their own width, the fovea small and elongate; beak 

 large, distinctly longer than the prothorax and broader than in the allied 

 species, rather gradually dilated at apex, densely rugose, the median carina 

 fine and very feeble; antennal funicle bristling with long white hairs, the two 

 basal joints elongate and ecjual. Prothorax one-fourth wider than long, the 

 sides parallel, just visibly converging toward base, rounded anteriorly to the 

 feebly subtubulate apex, the latter fully three-fourths as wide as the base; 

 disk strongl}' and closely rugose and distinctly carinate. Elytra not one-half 

 longer than wide and almost twice as wide as the prothorax, the sides parallel 

 and nearly straight from behind the humeri to the middle, then gradually 

 convergent, the apex rather narrowly rounded; humeri rounded but unusu- 

 ally widely exposed at base; disk strongly and arcuately declivous behind, 

 the sutural angles very slightly but obtusely prominent ; sculpture uniformly 

 finely, densely and strongly rugose, the serifil punctiires moderately large, dis- 

 tant and differing somewhat in size. Length 10.5 mm. ; width 4.9 mm. 



Colorado (Rocky Mts.). 



This species is allied to geminatus and the European palustris, 

 but is distinguishable from the former by its more obese form, 

 stouter beak and coarser punctuation, more exposed humeri, more 

 declivous elytra and denser vestiture, and from the latter by the 

 rostral carina and many other characters.

Rather narrowly' suboval, black, the rugosities shining; body 

 not very densely clothed throughout with small slender brown 

 and whitish scales, with minute denser whitish clusters separating 

 the serial punctures; dense sublateral vittiie of tiie pronotum 3'el- 

 lowish, narrow and strongly oblique ; each elytron with a small 

 rounded spot of dense yellowish scales just before the middle ; ab-
