OTlORIIYNCniDAE. 447 



The longer antennae as defined l)y (Ik; form of the outer joints 

 of the funicle, alone distinguish tliis group from the next. The 

 genera are not numerous and are known by the eharacters given 

 in the following table: — 



Metasternal side pieces entirely concealed by the elytra ; suture oWiter 

 ated ; hind tiUise with two short fixed sjjurs. Otiorhynchus. 



Metasternal side pieces linear ; suture distinct in its entire length ; 



Hind tibiae with two short, fixed, terminal spurs, first suture of aljdomen 



feebly arcuate ; front slightly transversely impressed. Sciopithes 



Hind tibiae without terminal spurs, first suture strongly arcuate at 



middle ; front not impressed. Agronus. 



Metasternal side pieces moderately wide, suture distinct; 



Hind tibiae without terminal spurs ; first suture of abdomen strongly 

 arcuate at middle. Neoptochus. 



The fixed spurs of the hind tibiae appear not to have been 

 noticed by any author; they are, in fact, difficult to see in some 

 species, while in others, quite large and prominent (0 inaia-ioi,. 

 We are not at present aware of the occurrence outside of the 

 tribe Otiorhynchini of any similar structure except in the female 

 of Ithycerus in which on each tibia in addition to the usual mucro 

 are two spurs, one of which at least is movable. The male has 

 the tibiffi simply mucronate. 



Otiorhynchus contains five species in our fauna known also in 

 Europe; Neoptochus one species in Florida; the other two genera 

 occur in California. 



Groiip III. — PeriteH. 



Antennae long, scape attaining or slightly passing tlie anterior 

 margin of the thorax; funicle variable in length, 7-jointed; club 

 oval. Tarsal claws connate. 



The cotyloid surfaces of the hind til)iK are entirely open in all 

 the genera of this group, glabrous in six, scaly in the remainder. 

 In the genera in our fauna the rostrum is comparatively or very 

 short, nothing occurs at all approximating the length of that of 

 Peritelus griseus of Europe. The ahe of the rostrum are diver- 

 gent in but one genus, and then but feebly. 



Our genera are as follows: — 



First ventral suture straight; scrobes lateral ; 



Alse of rostrum slightly divergent ; first two joints of funicle equal. 



Paraptochus.
