elevated. Elytra fully one-half longer than wide, twice as wide as the pro- 

 thorax, gradually narrowed behind, with the sides arcviate behind the middle, 

 the sutural angles individually somewhat acutely and distinctly prominent; 

 humeral angles rounded, transversely exposed at base; disk witli series of 

 punctures of varying sizes, the larger nearly one-half as wide as the intervals 

 but rounded, the surface finel}' and rather feebh- punctato -rugose. Length 

 10.5 mm. ; width 4.4 mm. 



Oregon. 



Allied to gerainatus, but differing in the more elongate form, 

 much smaller and less transverse prothorax, longer and almost 

 non-carinate beak, coarser serial punctures and more prominent 

 sutural angles of the elytra. 



Li. perforatus n. sp. — Elongate, the rugosities polished, black through- 

 out, the vestiture rather dense, consisting of gray or rust-brown slender scales, 

 variegated, especially toward il\& sides of the elytra, with small and paler 

 spots of dense scales, the obli(iue vittre of the pronotum rather narrow but 

 well marked, straight and generally with an external spur at the middle; 

 abdominal spots well developed. Head about one-half as wide as the pro- 

 thorax, densely squamulose, the scales of the beak longer, whiter and hair-like; 

 interocular fovea deep, narrow and fusiform ; eyes rather convex, separated by 

 somewhat less than twice their own width ; beak long and somewhat stout, 

 longer than the prothorax, straight but bent downward from the point of an- 

 tennal insertion, the surface roughly punctato-rugose, the carina feeble and 

 subobsolete near the base; antennis long, the second funicular joint much 

 longer than the first, the seventh transverse. Prothorax only slightly wider 

 than long, the sides subparallel, sometimes slightly convergent toward base, 

 rough and uneven, constricted behind the apex, the latter broad, truncate and 

 tubulate; disk rugose, the median carina narrow and strong, disappearing in 

 the median impression at the base. Elytra more than one-half longer than 

 wide, generally not quite twice as wide as the prothorax, the sides parallel 

 and broadly rounded, the apex triangular with feebly arcuate sides which are 

 discontinuous with the sides from the umbones to the base, the sutural angles 

 individually augulate and separated by a pronounced notch; disk gradually 

 rounded and decli\ ous behind in profile, the tips explanate, the surface uni- 

 formly and finely rugose, the series alternately perceptibly more approximate; 

 serial punctures differing greatly in size and generally widely spaced, the 

 larger very elongate, deep, coarse and perforate. Legs long, the femora with 

 a ring of pale scales at apicjil third as usual. Length 10.3-12.0 mm.; width 

 4.1-5.25 mm.
