A thorough morpliological study demonstrated that hyfioxantha and eurocilia 
are congeneric, and consequently Pcricopis falis into the syuohyjny of Dysschcma. 
In consequencc, and in accordance to the International Rules of Zoological No- 
mendatnre (Art. 5), we propose the new name DysJtcheinatidac to substitute the 
family name Pcricopidae Walker, 1869. 
Also a morpliological stndy of the genotypes of Scrmyla Walker, 185-1, 
Thebronc Boisduval, 1870 and Notophyson Boisduval, 1870, show that they are 
good gertera, and that Chetone Boisduval, 1870, is a synonym of Notophyson, 
since their genotypes are congeneric. 
The species bucklcyi Druce, 1895, is liere considered incertac saedis until a 
sotittd morpliological stndy of the type, or of topotypes, may ascertain its generic 
position. 
The conclusions of tliis work were hased on a morpliological stndy, par- 
ticularly of the genitalia. Opportunely the anatomical details of the sjiecies that 
have their nomenclatural sitnation directly reported in this paper will be published, 
as well as of others of which we have available material, towards establishing 
their respective generic situations. Only after this has beeu done it will be pos- 
sible to give a significative diagnosis of the family Dysschematidac.
