This genus was originally described by Förster in his 
Hym. Stud. IIH. and does not appear to have been found 
again later here in Europe, in any case nothing seems to 
be noticed anywhere in the literature, Schmiedeknecht 
however refers it in the Genera Insectorum and Aurivil- 
lius also in his work from 1897. In 1915 Wolff again 
mentions the genus. He complains first (p. 559) about 
Forster that he often creates new genera in his works 
without mentioning a single word of the species belonging 
to the various genera, and he next complains of Forster, 
and with very good reason according to my opinion, that 
he does not refer to his own works correctly. But when 
Wolff (p. 560) maintains in these works, how doubtful 
the base for our knowledge of Centrobia is, I am ab- 
solutely of the opinion that he is unjust towards Forster,
