CyYTTALIA. 
The type of this genus (C. griseipila) appears to be unknown 
to Australian entomologists. Mr. Blackburn, at the date* of 
publishing his tabulation of the Erirhinid genera, doubtfully 
describes two species (tarsalis and Sydneyensis) as congeneric, 
and associates them with Diapelmus ventralis and EHrichsoni 
(Pascoe). These four species I know, and they certainly are con- 
geners. I believe with Mr. Blackburn that Mr. Pascoe was 
wrong in referring the two latter species to Diapelmus (Hrichson 
describes the rostrum as “lineare,” and the eyes as “haud 
prominuli”); at the same time it is hardly likely that they can 
belong to Cyttalia.t Mr. Blackburn remarks? :—“ It is, I think, 
at any rate certain, that if the species I have called Cyttalia are 
not really congeneric with that on which the genus was founded, 
they cannot be referred to any other characterised genus.” I 
have a species from Western Australia which I believe to be a 
true Cyttalia, but which has appendiculate claws; it is even 
possible that it is C. griseipila, with the description of which it 
closely agrees, and had my specimens been taken in Sydney I 
should have had little doubt in referring them to that species. I

+It seems scarcely probable that Mr. Pascoe would designate a new 
genus, without at least referring to the species referable to it, and pre- 
viously described by him.
