JkRT. 18 NEW NORTH AMEEICAlSr WEEVILS CHITTENDEN 17 



First funicular joint at apex wider than second; second about one- 

 fourth longer, slender but at apex as wide as third, about as long 

 as third, fourth, and fifth together. Pronotum only a little wider 

 than long, feebly arcuate at sides; antescutellar impression mod- 

 erately shallow, without median impressed line; disk rather feebly 

 and indistinctly variolately punctate, punctures small, irregularly 

 placed, scarcely evident anteriorly; interspaces densely and dis- 

 tinctly punctulate. Elytra scarcely wider than pronotum, three 

 times as long as wide, sides parallel in basal two-thirds ; postscutei- 

 lar region nearly flat ; humeral angles scarcely visible ; surface with 

 quite regular rows of fine rounded punctures. Legs long, moderately 

 slender ; femora somewhat strongly clavate ; anterior tibiae strongly 

 serrate on inner margin ; surface of legs coated with fine, short, gray 

 hair-like scales. Vestiture of abdominal segments dense. 



Length, 10.5 mm. ; width, 2.7 mm. ; rostrum, 3 mm. 



Type locality. — Lake Okoboji, Iowa, July 6,1917 (L.L.Buchanan). 



r^/joe.— Female, Cat. No. 29027, U.S.N.M. Unique. 



A quite distinctive species named in honor of L. L. Buchanan. 

 The size, and the length and shape of the rostrum, are suggestive 

 of Sylvius Boheman, from which it is separated readily by the pro- 

 notal punctation. Superficially it resembles flexipennis, new species, 

 but it is wider and has a longer, more arcuate rostrum, with finely 

 punctulate surface throughout its length. That the second funicu- 

 lar is as long as the third plus the fourth plus the fifth is remarkable. 



LIXUS PLUCHEAE, new species 



Elongate cylindrical, a little less than four times as long as wide, 

 dark reddish brown, head and rostrum black, antennae a little lighter 

 red than body, densely coated with fine dull ocherous-yellow pu- 

 bescence. Rostrum shorter than prothorax, moderately thick, about 

 three times as long as wide, rather feebly arcuate on anterior surface, 

 nearlj^ straight on posterior, obsoletely carinate basally, surface 

 punctation partly obscured by vestiture, coarsely punctate between 

 the eyes with a tendency to form grooves, punctures finer toward 

 apex. Interocular fovea very small. Antennal scrobes beginning 

 about one-third from apex; antennae inserted a little above that 

 point or a little below the middle ; first and second funicular joints 

 subequal in length, second about as long as third and fourth together. 

 Eyes comparatively small, ovate, voider toward apex. Prothorax 

 about as wide as long ; wide at apex, sides nearly straight ; disk with- 

 out sulcus and without asperities ; deeply impressed at base in middle, 

 especially deeply in scutellar region, narrower and more shallow 

 apically; surface nearly smooth, coarsely, sparsely punctate; inter- 

 spaces finely and densely punctulate; vestiture composed of long,
