Coleopterological Notices, III. 197 



Basal joint of the funicle distinctly shorter than the second ; pronotal impres- 

 sion rather deep and distinctly limited, large, wide and extending to 

 apical fourth ; heak in the female hut very slightly longer than the pro- 

 thorax 16 soror 



lO — Beak finely but strongly, very densely punctate throughout. 



Pubescence throughout very dense and rather long, pale ochreo-cinereous 

 in color and concealing the punctuation of the beak from base to apex, 



the beak not at all carinate 17 laramieusis 



Pubescence very short, rather sparse, not concealing the punctuation of 

 any part ; beak with a distinct median carina. 



Elytra with apical tufts of long dense pubescence 18 mixtlis 



Elytra devoid of apical pubescent tufts 19 sobrinus 



Beak finely, sparsely punctulate, and, toward base and on the head, with 

 large deep scattered punctures ; pronotal punctures very coarse and 

 sparsely distributed ; prothorax with a small feeble ante-scutellar impres- 

 sion and more or less strongly constricted at the apex. 

 Vestiture on the elytra strongly mottled throughout, often broadly sparser 

 along the middle of each elytron but not forming a lateral vittiform line. 

 Beak very long and slender, fully as long as the prothorax in the male 



and longer in the female 20 sylvillS 



Beak shorter and much more robust, distinctly shorter than the prothorax 



in both sexes 21 scroliicollis 



Vestiture of the elytra more or less mottled toward the suture but forming 

 a broad, rather definite lateral condensation, which is joined at apical 

 fifth or sixth by a very short narrow vitta on the third interval ; beak 

 very slender, nearly as long as the prothorax in both sexes ; body slen- 

 der 22 perforatum 



Vestiture not at all mottled, forming a broad well-defined submarginal vitta, 

 which is joined at apical sixth by a narrow distinct vitta occupying the 

 entire length of the third interval ; fifth interval also feebly vittate ; beak 

 short and robust in both sexes, much shorter than the prothorax ; body 



more robust 23 semivittatus 



11 — Color black throughout 12 



Color rufo-testaceous, the elytral apices distinctly produced and rounded or 



subangulate ; pronotum longitudinally impressed throughout 13 



12 — Elytra constricted at the sides just behind the basal angles ; beak very 



long 24 macer 



Elytra not constricted at base ; beak moderate. 



Humeral angles prominent and tumid, the elytral width notably greater 



than that of the prothorax 25 jiilichi 



Humeral angles obsolete, the elytra at base not wider than the prothorax. 

 Prothorax not wider than long, conical, the pronotum narrowly and 

 feebly impressed throughout the length, deeply so at base. 



26 luculentus 

 Prothorax wider than long, only impressed near the base. 



Beak very sparsely punctate ; scattered punctures of the pronotum 

 coarse 27 nitidulus
