Goleopterological Notices, IV. 301 



Arizona, and probably also throughout the elevated central region 

 of Mexico. 



The following tabular statement may possibly facilitate the iden- 

 tification of the greater part of those species at present known to 

 collectors : — 



Anterior legs elongated in the male ; beak long, slender, strongly, evenly 

 arcuate at least in the female, the antennae inserted near the middle in 

 the latter sex ; femoral teeth minute ; species large and homologous with 



the European hnr/iinanus 2 



Anterior legs not elongated in the male ; beak long and slender, much longer 

 and with the antennre inserted at or near the middle in the female ; species 



moderately large 3 



Anterior legs not elongated in the male ; beak shorter, stouter and more nearly 

 straight, the antennse inserted near apical third in the male and but 



slightly less apical in the female ; species smaller 4 



2 — Elytra with long sparse erect and bristling setse ; beak in the female much 

 longer than in the male; basal joint of the anterior tarsi extremely 



elongate in the latter sex 1 inaeqiialis 



Elytra with short and more close-set erect setse ; beak not much longer in the 

 female ; basal joint of the anterior male tarsi subequal in length to the 



remainder 2 breTisetosilS 



Elytra devoid of erect setse ; beak only very slightly longer in the female ; 

 basal joint of the anterior male tarsi a little shorter than the remainder. 



3 muciclus 

 3 — Anterior femur of the male with a rather small, very acute tooth. 



Body piceous-blaok, the antennae rufous ; elytra distinctly and gradually 



inflated behind 4 laticollis 



Body much broader, pale ochreous-testaceous throughout, the sterna black- 

 ish ; elytra subparallel 5 a III plus 



Anterior femur of the male with a large rectangular tooth ; beak in that sex 

 shorter and stouter ; body dark rufo-testaceous, variegated with uneven 



darker spots 6 parvicollis 



4 — Elytra with erect bristling setae 5 



Elytra without erect setae 6 



5 — Prothorax distinctly constricted behind the apex. 



Body generally dark in color ; prothorax less transverse ; elytral setae sparse 



but long and conspicuous 7 Iiystrictlla 



Body pale ochreous-flavate ; prothorax short and strongly transverse ; erect 



setae more numerous and much shorter S hispidus 



Prothorax not, or but just visibly and broadly constricted near the apex. 

 Larger species, the prothorax rather large, strongly transverse and finely 

 punctate; beak longer; erect setae short and abundant, somewhat re- 

 curved 9 liirtiis 



Small species ; prothorax small, coarsely punctate ; beak vei-y short, barely 

 as long as the prothorax ; erect setae long, finer and sparser.
