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

 elytra rugose and feebly sulcate. [Type E. rufipes 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 seta^, 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 Eiiryvietopoti 

 abnorjne Lee] Metoponium 



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

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

 dently, though minutelv, 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. [Tvpe T'. lo77gipen7iis Csv.]. 



Telabis 



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. injiatiis Lee] ...Cryptadius 



5 — Antennas long and very slender, nearly as in the preceding group; 



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



prominent 6 



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

 zation, the eighth joint never elongate ; eyes rather small, trans- 

 verse, not prominent, about half divided by the lateral canthus of 

 the head 13 



6 — Body elongate, parallel 7 



Body oval, convex, glabrous, devoid of hind wungs ; tarsi spinulose or 



sparsely and very coarsely setose beneath 12 



7 — Surface glabrous S 



Surface pubescent 11 



8 — Tarsi pubescent beneath 9 



Tarsi with sparse stiff subspiniform set;v! beneath 10
