and extending to the middle. Pronotum about as wide as long, arc- 

 uate at sides, not quadrate, subtubulate at apex; disk convex, flat- 

 tened and feebly impressed in antescutellar region, deeply remotely 

 punctate. Elytra about two and a half times as long as wide, at 

 base little wider than pronotum, widening at humeri, thence parallel 

 for two-thirds their length, suddenly, strongly narrowed to apex, 

 extreme apices nearly closed. Disk distinctly, not deeply impressed 

 in scutellar region, impression wider than long, including three 

 intervals each side, humeral impression also distinct, narrow; strial 

 punctures rather small and deep, remotely placed, arranged in sub- 

 regular rows in type specimen, but distinctly confused in outer 

 basal half of elytra in paratype ; vestiture not mottled. First ventral 

 segment convex, unimpressed, second very long, distinctly longer 

 than third and fourth combined ; surface sparsely punctate, vestiture 

 whitish, moderately long, subocellate, forming a triangular yellow 

 tuft each side of fifth segment. Legs long, slender, with sparse 

 pubescence. 



Length, 6-8.4 mm. ; width, 1.4-2.7 mm.

The male is unknown. This species is distinctive in the sylmus 

 group. It is of similar form and closely related to sylvius Boheman 

 but distinctly slenderer, with much slenderer female rostrum, the 

 apex of which is nearly impunctate rather than distinctly punctu- 

 late, the lateral elytral vitta is somewhat narrower and the elytral 

 punctation is not so coarse nor so deep. In sylvius Boheman the 

 elytra, in perfect specimens, may have broad vittae or be entirely 

 mottled, and the rostrum in both sexes is sparsely pubescent. 



LIXUS ORDINATIPENNIS. new species 



Elongate subcylindrical, about three and one-third times as long 

 as wide, black, antennae dark brown; vestiture consisting of short, 

 fine, scale-like hairs, sparse on dorsum of elytra, denser at middle 

 of pronotum; sides of prothorax and elytra with an inconspicuous 

 narrow gray lateral vitta attaining the elytral apex. Rostrum in 

 the female about as long as the pronotum, robust, three times as long 

 as wide, subcylindrical, somewhat flattened anteriorly ; rather feebly 

 arcuate, widest near middle; comparatively coarsely and very 

 sparsely punctate in basal portion and at sides, punctulate at apex 

 below scrobes ; entire surface covered with gray pubescence partially 

 obscuring the sculpture. Second funicular joint shorter than third 

 plus fourth. Prothorax nearly as wide as long, basal three-fourths
