and rapidly descending. The supports of the deciduous pieces of tlie man- 

 dibles are moderately or very prominent. 



The genera knoM^n to occur in our fauna may be recognised by tlie 

 following table : 

 Articular face of hind tibiae glabrous, support 

 of deciduous piece moderately prominent. 

 Antennae stout, last joint of funicle short 

 broad, and very close to the club. Joints 



1-2 of tarsi, glabrous GRAPHORHINUS. 



Antennae more slender, joints of funicle 

 conical, the last distant from the club. 



Tarsi pubescent EPICJERUS. 



Articular face of hind tibiae scaly. Support 

 of deciduous piece very prominent. An- 

 tennae rather slender, club distinct ANOMADUS. 



The deciduous pieces of the mandibles are shown in one species of 

 EpicoBrus. They are falciform, moderately robust, obtusely pointed, with 

 the upper inner side concave, smooth and shining. 



GRAPHORHINUS Sch. 



GrapJiorMnus Schonherr, Gen. Cure, i, p. 510 ; indicated but not de- 

 scribed by Say. 



This genus has all the essential characters of Epiccerus, and differs only 

 in the following particulars : 



Antennae shorter, scape slightly clavate, attaining the eyes, funicle 

 7-jointed, first two joints slightly larger than the otliers, 3-6 as broad as 

 long, the seventh broader than long, and in close proximity to the club, . 

 the latter broadly oval and pointed at tip. Eyes nearly round, slightly 

 transverse. Cotyloid cavities of hind tibiae terminal {corbeilles ouvertes) 

 and glabrous, tarsi beneath glabrous slightly fimbriate near the tips. 



By the above characters it will be seen that the genus differs from 

 Epicmrus in the form of the antennae, the form of the posterior cotyloid 

 cavities and the vestiture of the tarsi. The species below being the type of 

 the genus, and as it diifers in several particulars from the Grapliorliinus as 

 described by Lacordaire from other species, these should constitute another 

 genus differing in the form of the antennas and the vestiture of the tarsi.

 Gen. Cure, i, p. 511. 



Body pyriform robust. Rostrum robust, quadrangular, slightly longer 

 than the head, tip feebly emarginate and with a smooth triangular space 

 limited behind by a chevron-lilve ridge behind which is a groove, above 

 trisulcate and a moderately deep transverse impression between the eyes, 

 median sulcus broad, lateral sulci short but deeper ; surface densely clothed 

 with cinereous scales and sparsely punctured. Thorax slightly broader at 

 base than long, sides arcuate converging to the apex, which is truncate,.
