' The species are thus arranged : — A. Prosternal spine gradually pointed. 

 Femoral lamina of posterior coxae gradually narrowed. Pronotum longer 

 than broad ; a. lateral edges of pronotum entire, hiud corners with sharp 

 ridge. *Antenn8e deeply serrated, as long as head and pronotum ; eyes granu- 

 lated {E. aterrimus). * 'Antennae filiform, as long as head and pronotum ; 

 eyes smooth {E. pilosus). b. Side edges of pronotum interrupted in middle, 

 hind corners without ridge ; antennae filiform, longer than head and pro- 

 notum; eyes granulated (E. ;jaZ/irf«/Ms). B. Prosternal spine compressed 

 behind the coxae ; antennae filiform ; tfemoral lamina of posterior coxae 

 gradually narrowing ; a. antennae longer than head and pronotum ; * pro- 

 notum longer than broad [E. sputator) ; ** pronotum broader than long 

 (jE. obscurus and E. lineatus). b. Antennae shorter than head and pro- 

 notum ; pronotum of equal length and breadth {E. ustulatus) ; ft femoral 

 lamina of posterior coxae pointed {E. marginatus). 



' Prof. Schiodte rejects the earlier attempts at a separation of the spe- 

 cies of this subgenus with entirely red elytra : he shows that the characters 

 adopted are unstable, and more particularly that the triangular form of the 

 third joint of the antennae, on which Kiesenwetter founds his A. satrapa, 

 is a sexual peculiarity, the second and third joints of the antennae varying 

 considerably in shape and size according to the sexes. The synonymy of the
