—83, appear that the genus is identic with Lathromeris 
Förster so that both of the two American species fidie 
Ashmead (Journ. Cin. Soc. Nat. Hist. XVII 1894 Ashmead 
and do. do. Webster) and cicade Howard (Canad. Ent. 
London, Ontario XXX, 1898 p. 102) rigthly are referred 
to the genus Lathromeris Förster. 
Ashmead certainly says in his first description that 
Lathromeris cicade has 3-jointed club, but Girault expressiy 
corrects this saying (p. 7): „club 4-jointed“ and the descrip- 
tion of the wings of the American species is certainly 
not quite identical with that of our European species but 
I do not believe that so much stress should be laid on 
these differences in the wings that this should be taken 
as an opportunity to found a new genus. I may per- 
haps be justified in hoping that my present paper may 
enable the American hymenopteorologists to decide 
whether the American species Lafhromeris fidie Ashmead 
and L. cicad@ Howard in the future can be rightly refer- 
red to Forster's genus or whether it will be necessary to 
found a new genus for them.
