I'ronotal punctures much smaller, the median line totally obsolete. 



2 coiTOsa 

 Body strongly depressed, rouglily sculptured, the elytral setae long, vei-y 



robust, dense and conspicuous 3 depressa 



d — Prosternum feebly impressed along the middle, the anterior coxae separated 

 by but slightly more than their own width ; large species, with very large 

 piotliorax, the latter nearly as long as wide, the elytra relatively short, 



the beak stout 4 millepora 



Prosternum flat, the anterior coxae smaller and more remote. 



Punctures of the elytral intervals broadly confused throughout. 

 Elytral setae coarse, long and conspicuous but not very dense. 



5 austera 

 Elytral set* very small, slender and only noticeable because of their 



greater abundance (3 insidiosa 



Punctures of the elytral intervals moderate in size, broadly confused only 



toward base, forming single series toward apex 7 SUl)toiisa 



<i — Elytral punctures larger, distinct and generally close-set ; intei-vals nar- 

 row ; body less slender 7 



Elytral punctures very minute and remote, the intervals wide, flat 9 



T — Body, legs and beak intense black throughout; small species... 8 argllta 

 Legs and beak rufous, the entire body also fretiuently more or less rufo-pice- 



ous 8 



S — Body rufo-ferruginoHS, the elytra black, smoother, with alutaceous lustre, 

 the interstitial punctures rather less coarse and separated by about tlieir 



own diameters 9 aildax 



Body unicolorous throughout, black or more or less rufo-piceous ; inlerslilial 

 punctures always coarse, deep and occupying ttie entire width of the 

 intervals or vary nearly. 

 Larger species, the prothorax nearly as long as wide and the elytra rela- 

 tively shorter. 



Surface strongly shining, black 10 stictica 



Surface opaqite from the extreme density of the sculpture ; body daik 



blackish-piceous in color 11 luystica 



Small species, the prothorax distinctly transverse. 



Elytral setae very small and inconspicuous ; legs and beak pale rufous. 



12 egena 

 Elytral setae longer, conspicuoits ; legs and beak darker, piceo-rufous, the 

 former a little shorter. 

 Sides of the prothorax parallel ; elytral setae erect, bristling, those of 



the strial punctures almost as long as the others 13 anilbiglia 



Sides of the prothorax feebly divergent from the base; elytra! setae 

 shorter, more inclined, more distant and less conspicuous ; tliose of 

 the strial punctures very small and scarcely at all visible. 



14 patiperella 



9 — Body narrow, parallel ; vary small species 15 sei'iata 



lO — Elytral intervals wider than the stiiae 11 



Elytral intervals not wider than the grooves 14
