Species bicolored, black with base of elytra, metasternum and abdomen 



rufous hamiltoni Slosson. 



Species unicolored (when mature). 



Thorax truncate at base, antennae post median bohemanni Horn. 



Thorax bisinuate at base, antennae median or anterior to middle. 



Thorax broader than long, sides arcuate, surface very unevenly 



punctured platalea Say. 



Thorax longer than wide, sides slightly arcuate or' straight. 

 Basal portion of rostrum longer than dilated portion. 



subareatus Boh. 

 Basal portion of rostrum equal to the dilated portion. 



Rostrum elongate, apical portion distinctly wider than basal 

 and rather suddenly dilated. Thorax narrower than the 

 elytra. 

 Thorax somewhat cuneiform, with sides convergent for- 

 wards from point just anterior to base, with lateral 

 discal punctures much finer and with median line at 

 base often cariniform. 

 Larger species, over 4 mm. in length, with moderately 

 large elytral punctures which diminish but little 

 in size posteriorly, rostrum about twice as long 

 as broad. 

 Thorax much narrower than elytra, sides gradually 

 and distinctly convergent from middle to apex 



where but slightly constricted piniphilus Boh. 



Thorax but little narrower than elytra, sides slightly 

 convergent from just in front of base to near 

 apex where they become rather suddenly con- 

 stricted lupini n. sp. 



Smaller species, less than 4 mm. in length, thorax 

 almost as wide at base as elytra, gradually con- 

 vergent forwards from in front of base to apex 

 where but slightly constricted. Elytra with rather 

 fine punctures which diminish rapidly in size pos- 

 teriorly. Beak rather broad, less than twice as long 



as broad impressus Boh. 



Thorax not cuneiform, with sides almost parallel or 

 slightly arcuate from near base to near apex where 

 they become suddenly constricted. 

 Thorax distinctly narrower than elytra and somewhat 

 sub-depressed. 

 Head, including eyes, cuneiform, gradually con- 

 vergent to base of rostrum, rostrum about 

 twice as long as wide and with apical portion 

 distinctly wider than basal.
