28 — Elytral striae obsolete, represented at the base by small and not very 



conspicuous fovese : body subglabrous; tarsal claws single £isonyx 



Elytral striae normal, distinct, not foveate at base. 



Tarsal claws two in number, completely connate in basal third to half ....29 



Tarsal claws single 30 



29 — Beak long, slender, the antennae inserted behind the middle; elytral striae 

 very fine but broadly, feebly impressed and very coarsely punctate ; body 



subglabrous and with remotely scattered white scales Zygobaris 



Beak short and stout ; body squaraose. 



Basal joint of the antennal funicle moderate in length ; elytra witli large re- 

 motely scattered white scales in addition to the denser squamules ; species 



very small CatapastUS 



Basal joint of the antennal funicle very long, sometimes as long as the entire 

 remainder ; elytral vestiture often vittate or with denuded spots, but 

 without widely dispersed coarser scales ; species moderately large, more 



or less elongate-oval, or narrower and parallel, convex RarillllS 



30 — Body cylindrical and very slender ; basal joint of the antennal funicle 



long Barileptoii 



31 — Beak long, very slender but strongly inflated behind the point of antennal 

 insertion, separated from the head beneath by a deep transverse constric- 

 tion ; erect setae spiniform and conspicuous Ellliyssobia 



Beak shorter, without basal constriction, the erect bristles much shorter.

This is a large genus of almost universal distribution, but much 

 more developed in North and South America than in Eurasia. 

 Assuming the definition of the genus given in the preceding table, 

 the species occurring within the territory embraced by the present 

 monograph are of an oval or oblong-oval convex form of body, with 

 semi-glabrous and usually strongly shining integuments. As com- 

 pared with most of the other genera of the tribe the sculpture is 

 rather coarse and only moderately dense. The vestiture consists 

 of small semi-erect or recurved sette, which are always sparse and 

 never broadly squamiform. 



The rostrum is invaria))ly short, often excessively so, never quite 

 equalling the prothorax in length, and, in many cases, not more 

 than one-half as long. On comparing this form of beak with that 

 of Centrinus, Limnobaris or even Onj^chobaris, it can reasonably 

 l»e inferred that the hal)its of the species are notably, if not essen- 

 tially, ditferent from those of the latter genera.
