Megacelum, Fieber, Crit. Gen. p. 21 (1858) ; Eur. Hem. p. 64. 249 (1861); Walk. Cat. Het. vi. 
p. 42 (1878). 
In this genus the extreme apex of the scutellum is deflexed and curved downwards, 
a character which with its subopaque coloration will sufficiently distinguish it from 
the preceding genus.
