As these g^^nera are closely allied, it is thought best (to avoid 

 repetition) to give the characters they possess in common, as 

 follows : — 



Head convex, not entirely concealed by protliorax; ocular fo\ea 

 moderately distinct. Eyes moderately large, widely separated. 

 Prothora.r transverse; ocular lobes obtuse. ScuttUinn distinct. 

 Elytra convex, cylindrical, base trisiiiuate, shoulders square. 

 Metasternnm large, longer than basal segment of abdomen; 

 episterna distinct. Abdomen with distinct sutures, intercxal 

 process rounded, 1st segment as long as 2nd-3rd combined, ord- 

 4th conjointly longer than ind but much longer than 5th. Legs 

 moderate; tibiae compressed, straight or feebly bisinuate beneath; 

 tarsi moderately long, 3rd joint wide, deeply bilobed, claw-joint 

 elongate. Convex, cylindrical, squamose, punctate, fascicuUte, 

 winged. Although closely allied, the following table should 

 render their separation easy : — 



Pectoral canal open, rostrum longer than prothorax Isax. 



Pectoral canal closed, rostrum the length of prothorax. 



Eyes coarsely faceted Menios. 



Eyes finely faceted. 



Eostrum thin PsEur-oiiETiRrs. 



Rostrum stout. 



Femora dentate . Metyrus.*
