suggested. There is nothing to indicate that Miccotrogus possesses 

 greater systematic value than any one of these American groups. 



The species may be easily recognized by the following charac- 

 ters : — 



Subgenus I. 

 Elytral vestiture narrowly vittate, often alternating fulvous and cinereous on 

 the intervals, the strise broadly visible ; anterior tibiae of the male strongly, 



acutely toothed internally near the middle 1 liiieellllS 



Elytral vestiture nearly uniform in color, the striae indicated by fine and in- 

 distinct i^artings ; anterior tibiie not dentate in the male. 

 Beak thick, only feebly diminishing in diameter from base to apex. 



Body broadly oval, the scales very narrow and hair-like 2 sordidus 



Body more narrowly oval, the scales broader and more densely crowded. 



3 tectus 

 Beak thick at base, rapidly and finely attenuate toward apex ; elytral ves- 

 titure mingled with a vei-y few widely scattered rounded scales toward 

 apex 4 arator 



Subgenus II. 

 Abdomen with sparse semi-erect setse, in addition to the dense squamosity. 

 Setfe borne by the strial punctures of the elytra long semi-erect white and 

 conspicuous. 

 Prothorax less transverse, with a broad median vitta which is entirely 

 clothed with large white imbricated scales ; setre throughout the body 



robust 5 SOltaili 



Prothorax strongly transverse, with a very fine white median line which 

 contains no large non-strigose scales, except in the broader portion near 



the base; setse throughout longer and fine (J llirtellllS 



Setse borne by the strial punctures short, thicker, recumbent and incon- 

 spicuous 7 aratus 



Abdomen densely squamose but without trace of setse ; scales of the elytra 

 smaller and more densely imbricated along the suture than elsewhere. 

 Beak very feebly narrowed toward apex ; prothorax a little less transverse, 

 wider at tlie middle than at base ; elytra with many more setse than scales 



on the disk 8 seniisqaniosiis 



Beak rapidly and finely acuminate, thicker toward base ; body stouter ; 

 sides of the prothorax parallel behind ; elytra with many more large 

 whitish oval scales than setae 9 lailiellosiIS 



Subgenus III. 

 Beak short, feebly tapering from base to apex ; elytra with large imbricated 

 scales and very robust recurved fulvous setae 10 pi'Olixus 



Subgenus IV. 

 Elytra without long erect bristles, although sometimes with abundant short 

 strongly recurved seta;, which are not very conspicuous.
