mentions that a recurrent vein was not present at the base of the 
wings. I think it is due to a mistake. Nathan Banks, who 
has seen the type-specimen in British Museum in 1912, states 
(Trans. Amer. Ent. Soc. Vol. XXXIX, p. 216—17, 1913) that a 
recurrent vein is present at the base of the forewings; whether it 
is present also in the hindwing as in R. magna, Banks does not 
mention, Nathan Banks has seen the type-specimen of R. magna 
(loc. cit., -p. 218). 
Rapisma magna has great likeness to R. viridipennis; but the 
greenish colour is not so distinct, and the ,,indistinet ferruginous 
dots and oblique stripes” on the forewings are not present. It also 
has a larger size.
