458 A SECOND NOTE ON THE CARENIDES, 



rounded, but well-marked ; base short, bisinuate, the middle very 

 lightly and broadly produced backwards ; border wide, its edge 

 hardly upturned in front, becoming more decidedly so backwards, 

 very strongly and obliquely reflexed at posterior angles, narrower 

 and with a very light median sinuosity on middle of base ; 

 marginal channel wide ; median line lightly impressed ; some 

 transverse striolae across median line near base, but basal part of 

 prothorax hardly defined ; two marginal punctures on each side 

 as usual. Elytra broadly ovate (13 x 11-5 mm.), widest before 

 the middle, lightly rounded on sides, very little narrowed to base, 

 decidedly narrowed to apex, convex ; base lightly and broadly 

 emarginate ; shoulders not prominent ; humeral angles well 

 marked, obtuse, rather square ; margin narrow on sides, wider 

 towards apex, wide and flat behind shoulders; border reflexed, 

 very strongly so at shoulders, extending past humeral angles, not 

 ending in a thickened humeral projection ; a row of small 

 punctures on base of each elytron ; a row of lightly impressed 

 punctures along lateral margins ; suture well-marked. Proster- 

 num almost flat between the coxse, with a very light median 

 excavation. Anterior tibise bidentate, three or four small external 

 teeth above the two large ones. 



Length 27, breadth 11*5 mm.

This species is allied to E. minor ^ Macl., from which the broader 

 prothorax with more strongly marked posterior angles and the 

 middle of the base less produced backwards distinguish it. From 

 E. concolor, SI., also an allied species, the far less convex elytra 

 much more narrowed to the apex at once separate it. There 

 seems a possibility that E. j^olitus may prove to be Scaraphites 

 hopei, Casteln., as Count de Castelnau says that species might be 

 taken for E. 7ninor, Macl., and E. politics has a decided superficial 

 resemblance to E. viinor ; but Sc. hopei is said to have the 

 "humeral angles rounded, and not advanced"; the inference 

 being suggested that de Castelnau considered these angles advanced, 

 but not rounded, in E. tninor ; in E. politus they are less rounded
