tumescent polished sides ; elytra short, a fourth longer than wide, less 

 than twice as long as ihe proihorax and a third wider, the humeri less 

 tlian usually exposed, the converging sides arcuate ; apex raiher obtuse ; 

 stria; somewhat more than a third as wide as the interval.*, with the 

 squama* rather narrow : femoral teeth rather strong, acute ; fifth ventral 

 flat, trapezoidal, truncate at lip, glabrous at the middle of the tip and with 

 long but not dense hairs laterally at apex. Length, cJ , 4 7 mm.; width, 

 2.15 mm.; length of rostrum, cJ . 2-5 '"'"• Texas (.Alpine), Wickham. 



To be readily known by its short pliim|) form, unusually small size, 

 short legs and other characters mentioned in the description ; it is not 

 closely allied to any other of our species. 



b — Prot/iorii.x relatively smaller in size. 



This grou|> includes most of the species having short beaks. Obtusus 

 IJI., Casey i Chit. { = dre7'ir0sfris , Csy. ), and monticola constitute a 

 peculiar section of the group, having the rostrum very short in both sexes, 

 stout and only a little longer in the female than in the male, the antenn.e 

 inserted slightly behind the middle in the former and correi:i)ondingIy but 

 little beyond the middle in the latter sex. The group contains, besides 

 the obtusus section, two other minor sections, one having the male beak 

 very short, in fact scarcely half as long as body and having as representa- 

 tive species confusor Ham., baculi Chit , and the following : 



/)'. loivensis n. sp.— Hody ( ^ ) larger and a little stouter than in 

 con/usor, similar in colour, sculpture and vestiture, except that the medial 

 scales of the pronotum are less hair like and the elytral striai notal)ly finer, 

 the beak ( (J ) much stouter, with many longitudinal grooves behind the 

 point of antcnnal insertion, and, as usual, slightly narrowed before that 

 point, very feebly enlarged toward tip ; antenn.-e inserted well beyond the 

 middle, stouter than in confusor, the funicular joints two to four diminish- 

 ing very gradually in length, the second but little longer than the third and 

 much more notably shorter than the first than in confusor ; proihorax as 

 in that species, a third wider than long and sinuously narrowed anteriorly 

 but relatively a little larger ; elytra more obtuse posteriorly; legs longer, 

 the femora strongly and acutely toothed ; fifth ventral feebly and not very 

 definitely impressed and not more sparsely clothed medially ; pygidial 

 pubescence abruptly limited superiorly. Length, f< , 7.3 mm.; width, 3 3 

 mm.; length of rostrum, ^, 2.6 mm. Iowa (Keokuk). 



The elytral maculation of darker pale brown scales is very feebly 

 defined; there is evidence however of the transverse pale band at apical
