hind tarsi as long as the fourth; body depressed, parallel, the 

 elytra rugose and feebly sulcate. [Type E. r7ifipes Esch.] . 



Eurymetopon 



Eyes large, more or less prominent, subentire; head with a distinct 

 supra-orbital carina, curving outwardly before the eyes; epistoma 

 never emarginate, truncate or arcuato-truncate ; mandibles ridged 

 externally above ; antennae slender, extending about to the base 

 of the prothorax, cylindric, the four last joints broader, com- 

 pressed, forming a loose club, the eleventh as long as the tenth or 

 longer but always distinctly narrower, more or less pointed; 

 scutellum distinct, transverse or quadrangular; elytra never 

 strongly rugose and nearly always having distinct serial punctures, 

 the series wholly unimpressed as a rule 3 



3 — Tarsi beneath with numerous long stiff setas, the basal joint of the 



posterior shorter than the fourth ; front broadly truncate or sinuato- 

 truncate, even, not biemarginate; hind wings well developed 

 to vestigial or obsolete; prothorax generally fully as wide as the 

 elytra, sometimes very slightly narrower. [Type Eurvnietopoti ^o. 

 abnoj'me Lee] Metoponium 7 ^ 



Tarsi with very few short sparse spiniform sette beneath, the basal 

 joint of the posterior longer than the fourth ; frontal margin evi- 

 dently, though minutely, biemarginate; sculpture finer as a rule, 

 the lustre more generally subopaque, though frequently polished ; 

 prothorax generally very distinctly narrower than the elytra 4 



4 — Body elongate, with fully developed wings; prothorax more 



nearly parallel, with rounded sides and acute basal angles as in 

 the preceding genus; basal joint of the hind tarsi much longer 

 than the fourth; scutellum well developed, nearly uniform, angu- 

 late and but slightly transverse. [Type T. longipennis Csy.]. 



Telabis --j\-^^ 



Body broadly oval, without wings, the prothorax narrowing from base 

 to apex, with very obtuse basal angles; scutellum small; front 

 broadly, feebly trilobed. [Type C. injlatus Lee] ...Cryptadius

eyes large, subentire or not deeply emarginate and more or less 

 p ro m i n e n t 6 



Antennae shorter and rather stout, though of the same general organi-
