TRIBE II. CYPHINI. 121 



on sides of thorax and broken lines on the elevated intervals of elytra. 

 Beak very short and broad, deeply notched at tip. Funicle 7-jointed, the 

 first joint as long as the two following. Thorax subcylindrical, apex feebly 

 rounded, as wide or slightly wider than base, sides feebly curved; disc 

 strongly constricted before and behind the middle, coarsely and sparsely 

 punctate. Elytra one-third wider at base than thorax, striae with rows of 

 close-set punctures; intervals convex, the alternate ones more or less ele- 

 vated. Length 2.5 mm.

Tribe II. CYPHINI. 



In this tribe the beak is robust, acutely and deeply notched 

 at tip and sides and with a fine median groove; fnnicle 7-jointed, 

 its second joint usually longer than first; marginal or tenth 

 stria of elytra often confluent with the ninth at one-third from 

 base; second ventral segment as long as or longer than the two 

 following, separated from the first by a strongly curved suture. 



KEY TO EASTERN GENERA OF CYPHINI. 



a. Tarsal claws free; second joint of funicle longer than first; corbels of 



hind tibiae cavernous. 



&. Elytra wider at base than thorax, their hurneri prominent. 

 c. Scape long, scaly, passing the eyes behind; articular surface of 

 hind tibiae scaly; alternate elytral intervals strongly elevated. 



XVIII. COMPSUS. 



cc. Scape short, stout, not passing the eyes; articular surface of hind 



tibiae glabrous; alternate intervals not elevated; antennal grooves 



short, suddenly curved downwards. XIX. BRACHYSTYLUS. 



bb. Elytra oval, not wider at base than thorax, their hurneri rounded; 



scape much more slender, usually reaching the thorax. 

 d. Articular surface of hind tibiae scaly; front tibiae not toothed 

 within; tenth elytral striae confluent with the ninth. 



XX. ARTIPUS. 

 dd. Articular surface of hind tibiae glabrous; front tibiae denticulate 



within; tenth elytral striae entire. 



e. Joints of funicle elongate, the second as long or longer than the 

 first. XXI. PANTOMORUS. 



ee. Joints of funicle short, the second shorter than the first. 



XXII. LEPIDOCRICUS. 



aa. Tarsal claws connate; second joint of funicle equal to first; corbels 

 of hind tibiae not cavernous; antennal grooves deep, directed towards 

 the eyes but not reaching them. XXIII. APHRASTUS. 



All of these genera except Pantomorus are placed in the group 

 Platyomina in the Biologia, characterized by the antennal 

 groove being superior, short, parallel or divergent; eyes not 

 strictly lateral; elytra 10-striate; anterior tibiae unguiculate or 

 unarmed; posterior tibiae laminate at apex; tarsal claws free 

 (except in ApJirastus) ; body densely squamose. Pantomorus is
