Comparative Zoology and the literature, but against the 
collection of the British Museum, which contains Black- 
burn’s types and specimens identified by Sloane. The present 
new species all go into Clivina in the strict sense in Kult’s 
classification {Acta Soc. Ent. Cechosl. [Czecholovakia] 
XLiv, 1947, 26-37). 
Clivina frenchi Sloane (1896, p. 159) 
Previously known from North Queensland and from Lake 
Callabonna, South Australia. I took a series of specimens, 
which agree exactly with the description, near WiLUNA, 
interior of Western Australia, September 28 to October 
3, 1931, some on the shores of Lake Violet (near Lake Way) 
and others beside water holes on Mr. Alfred G. Paterson’s 
station, ‘‘Yandil”. These specimens vary in size from about 
7.0 to 9.5 mm., and in color from dark piceous to rufous 
with head and prothorax slightly darker. The elytral striae 
are all free at base in most specimens, but the basal end of 
the 5th stria is very close to that of the 6th and occasionally 
the two are connected, leaving only 4 striae free at base. 
This is an example of the sort of variation, affecting Sloane’s 
group characters, which has not yet been properly studied 
in most Australian’ and which must be understood 
before the species can be finally arranged in natural groups. 
C. frenchi is apparently closely allied to C. obsoleta Sloane 
(and to the following new species), although Sloane put 
f)‘cnchi and obsoleta in different groups. 
Clivina diluta n. sp. 
Parallel, cylindrical, but not more slender than usual; 
head very large, neck wide; shining, head and prothorax 
piceous or castaneous, elytra more or less dilute brown; 
body below piceous or dark rufous, somewhat paler an- 
teriorly; anterior legs rufous, antennae and middle and 
posterior legs brownish testaceous. Head 7 8 or slightly less 
wide as prothorax (by measurement — to the eye, the head 
seems virtually as wide as prothorax) ; mandibles rather 
short; clypeus with middle part separated from wings, 
depressed, and rather strongly emarginate at middle, with
