Basal portion of rostrum with sides parallel, 

 punctures of thorax more regular as to size. 



ponderosa n. sp. 



Basal portion of rostrum with sides distinctly 



divergent anteriorly, punctures of thorax more 



irregular as to size quadricoUis n. sp. 



Head, including eyes, not distinctly cuneiform, sud- 

 denly constricted to base of rostrum, rostrum 

 broad and flat on top, less than twice as long as 

 broad, sides of basal portion parallel and apical 



portion but little wider than basal texanus n. sp. 



Thorax but little, if any narrower than elytra. Head 

 rather suddenly constricted to base of rostrum. 

 Thorax shining and less convex dorsally, without 

 concavity posteriorly, with punctures moderate 

 and well separated. Rostrum with sides of basal 

 portion parallel and apical portion moderately 



■dilated ellipticoUis n. sp. 



Thorax less shining, quite convex dorsally and with 

 median line concave behind, punctures coarse and 

 approximate. Rostrum stout, sides of basal por- 

 tion divergent forwards, apical portion greatly 



dilated concinnus Boh. 



Rostrum broad and short, apical portion more gradually 

 dilated and but little wider than basal. Thorax as wide 

 as elytra. 

 Thoracic punctures coarse and close together. Elytral 

 punctures somewhat finer, approximate and crenulate. 

 Rostrum non-sulcate. 

 Color black, striae deeper and broader at base, punc- 

 tures of thorax coarse and cribrate at sides. All 

 joints of funicle of about same width and club at 



least twice as wide as funicle creimtus Horn. 



Color more piceous, striae but slightly deeper and 

 broader at base, punctures of thorax rarely cribrate 

 even at side. Outer joints of funicle distinctly 

 broader and club not twice as wide as funicle. 



corticola Say. 



Thoracic punctures coarse and distant. Elytral punctures 



fine and well separated, not crenulate, rostrum sulcata.
