366 A Preliminary Monograph of the 



The following table will, it is hoped, prove of some service as^^ 

 an aid to identification: — 



Body less slender, sometimes quite robust, more convex, the pronotum 

 generally not at all impressed, although sometimes exhibiting very- 

 feeble traces of the usual two impressions. 

 Prothorax widest at or near anterior third, the sides at this point 

 more strongly rounded and evenly coarctate to the apex. 

 Eyes smaller, but very slightly prominent and not so coarsely 

 faceted, the tempora very slightly visible behind them, broadly 

 rounded and convergent posteriorly, and distinctly less prominent 



than the eye 45 pudicu§^ 



Eyes very convex, prominent, more coarsely faceted as usual. 

 Form more robust; prothorax but slightly narrowed toward base^ 

 the sides parallel in the apical half and strongly arcuate; legs 



pale. , 46 robu§tulu» 



Form more slender; prothorax strongly narrowed toward base,, 

 the sides strongly rounded in the anterior third. 

 Eyes smaller, scarcely longer than the first antennal jointr 



47 confiiii» 

 Eyes much larger and more prominent, very coarsely faceted^ 

 distinctly longer than the first antennal joint. 



48 pauperculus 

 Prothorax gradually and moderately narrowed from apex to base and 

 broadly, evenly, and rather strongly arcuate; body rather slender 

 and convex. 

 Pronotum with a distinct median impunctate line extending from 

 the basal margin to the apex, gradually becoming broader through- 

 out its length 49 lang[uidu» 



Pronotum without a median impunctate line, the punctures a little 

 more sparsely distributed in the middle near the apex. 



50 bi|»uiicticollis 

 Prothorax widest at or near the middle, the sides at this point rather 

 narrowly rounded and very obtuse, thence parallel or feebly con- 

 vergent and more or less feebly arcuate to the apex, and more 

 distinctly convergent and more nearly straight to the base. 

 Size larger, not less than 2 mm. in length; pronotal punctures 

 distinctly separable, the interspaces shining; eyes normal for 

 the group and without trace of tempora. 

 Prothorax large, as wide as the elytra. 

 Punctuation excessively fine and dense, lustre dull; median 

 impunctate line of pronotum very narrow. 

 Piceous; sides of prothorax in anterior half parallel. 



51 §iinplarius 



Castaneous; abdomen piceous; sides distinctly convergent 



from behind the middle to the apex 52 pallidiilu»
