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 striae broadly visible ; anterior tibiae of the male strongly, 



acutely toothed internally near the middle 1 lineellllS 



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

 distinct partings ; anterior tibiae 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 sordidtlS 



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 very few widely scattered rounded scales toward 

 apex 4 arator 



Subgenus II. 

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

 Setae 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 ; setae throughout the body 



robust 5 soltaui 



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; setae throughout longer and fine 6 llirtellllS 



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

 spicuous 7 aratus 



Abdomen densely squamose but without trace of setae ; 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 the middle than at base ; elytra with many more setae than scales 



on the disk 8 semisqamosus 



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 lailiellosilS 



Subgenus III. 

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

 scales and very robust recurved fulvous setae 10 prolixus 



Subgenus IV. 

 Elytra without long erect bristles, although sometimes with abundant short 

 strongly recurved setae, which are not very conspicuous.
