TRIBE XVI 1 1. BARIXI. 397 



slightly wider than long, disc with a broad, median smooth line, finely 

 unevenly and very sparsely punctate. Elytra at base as wide as thorax, 

 striae coarse, rather shallow; intervals nearly twice as wide as striae, each 

 with a single row of punctures which vary much in size. Length 3.3 mm. 



Described from Florida without definite locality. 



GOT (11,189). LIMXOBAKIS OBLITA Casey, 1892, 634. 



Elongate-oval, moderately convex. Black, shining, subglabrous; legs 

 and antennae piceous; elytra minutely alutaceous. Beak slender, about 

 as long as head and thorax, its punctures fine, linear, rather sparse. 

 Thorax slightly wider than long, disc distinctly constricted at an unusual 

 distance behind the apex, rather coarsely, deeply and closely punctate; a 

 median line on basal two-thirds and a wide apical margin devoid of punc- 

 tures. Elytra distinctly wider and nearly twice as long as thorax; sides 

 parallel from base to apical third, then converging to tips; striae deep, 

 abrupt, rather coarse; intervals somewhat concave, one-half or more wider 

 than grooves, each with a row of small, close-set, uneven punctures. Length 

 3.5 mm. 



Known only from the Wisconsin type. 



GROUP B. 



Those of our eastern species, 11 in number, belonging to this 

 group, are separated as follows: 



KEY TO SPECIES OF GROUP B. 



a. Piceous-black, the elytra and legs reddish-brown, the former blackish 

 along the suture; surface densely but unevenly clothed throughout 

 with elongate-oval, yellowish-white scales. 60S. GRISEA. 



aa. Black; surface subglabrous except in longula. 



b. Second joint of funicle shorter than the next two; prosternum

 c. Form more or less oblong-oval; beak very slender, swollen above 



at base, its transverse constriction distinct. 



d. Elytral intervals with punctures confused; beak in both sexes 

 shorter than thorax; surface feebly shining, alutaceous.
