1 The species are thus arranged :—A. Prosternal spine gradually pointed. 
Femoral lamina of posterior coxe gradually narrowed. Pronotum longer 
than broad; a. lateral edges of pronotum entire, hind corners with sharp 
ridge. *Antennz deeply serrated, as long as head and pronotum; eyes granu- 
lated (£. aterrimus). **Antennee filiform, as long as head and pronotum ; 
eyes smooth (2. pilosus). 6. Side edges of pronotum interrupted in middle, 
hind corners without ridge; antennee filiform, longer than head and pro- 
notum; eyes granulated (H. pallidulus). B. Prosternal spine compressed 
behind the coxe; antenne filiform; +femoral lamina of posterior cox 
gradually narrowing; a. antenne longer than head and pronotum; * pro- 
notum longer than broad (EH. sputator); ** pronotum broader than long 
(E. obscurus and E. lineatus). 6. Antenne shorter than head and pro- 
notum ; pronotum of equal length and breadth (E. ustulatus) ; t+ femoral 
lamina of posterior coxie pointed (#. marginatus). 
? Prof. Schiddte 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 antennz, on which Kiesenwetter founds his A. satrapa, 
is a sexual peculiarity, the second and third joints of the antenne varying 
considerably in shape and size according to the sexes. The synonymy of the
