OTIORFIYNCHIDAE. 437 



Anterior tibia; dilated at tip ; scaj^e long, passing the eyes. 



Tkigonobcivia:. 

 Third joint of tarsi not wider tlian second, and feebly emarginate. 



Calyptili.i. 



Group I. — Minyomeri. 



Rostrum stout, cylindrical, as long as the head, and very little 

 narrowed to the tip. Scrobes deep, well defined, suddenly arcnate 

 in front, gradually wider behind and passing beneath the eyes. 

 Mesosternal side pieces unequal. Metasternal episternum linear, 

 suture distinct. Intercoxal process very broad and very short. 

 Hind coxa3 very small. Corbels of hind tibiae open, tarsal claws 

 free. , 



The form of the head, rostrum, and scrobes resembles somewhat 

 that of Pandelotejus of the Second Division, but the structure of 

 the sternal side pieces excludes the present genus from any such 

 association. According to the system adopted by Lacordaire, 

 this genus would be placed in the BrachydetHdes v)-ais. 



Two species of Minyomerus are found in Colorado and Arizona, 

 the latter one extending to California. 



Group II. — Epicaeri. 



The species composing this group are more or less pyriform, 

 the body above and beneatli densely scaly, the elytra of a pale- 

 brownish or luteous color with the tip and two sinuous bands 

 much paler. The rostrum is rather stout, usually longer than 

 the head, the scrobes deep, well defined, and rapidly descending. 

 The supports of the deciduous pieces of the mandibles are mode- 

 rately or very prominent. 



The genera known to occur in our fauna may be recognized by 

 the following table : — 



Articular face of hind tibia3 glabrous, support of deciduous piece moderately 

 prominent ; 

 Antenna; stout, last joint of funicle short broad, and very close to the 

 club; joints 1-2 of tarsi glabrous. Graphorhinus. 



Antenna; more slender, joints of funicle conical, the last distant from 

 the cUib; tarsi pubescent. Epicaerus. 



Articular face of hind tibiae scaly ; support of deciduous piece very promi- 

 nent ; antennse rather slender, club distinct. Anomadus. 



The deciduous pieces of the mandibles in Epicaerus are falci- 

 form, moderately robust, obtusely pointed, with the upper inner 

 side concave, smooth, and shining.
