Darling ton — Australian Carabidae 
53 
tralian Carabidae after (I hope) another collecting trip to 
Australia and accumulation of much more material. The 
later work is planned to take the form of revisions with 
comparative illustrations. Since I cannot foresee the exact 
forms of illustration which will prove most useful in dif- 
ferent groups, I do not plan to illustrate the present pre- 
liminary series. 
All statements of proportions, e. g. the relative widths of 
head and prothorax, in my descriptions are based upon 
actual measurements made with a ruled ocular in a binocular 
microscope. It is not possible to estimate proportions accu- 
rately without measuring. Width of head includes the eyes ; 
width of prothorax is greatest width ; length of prothorax, 
length at middle including margins, but not including ad- 
vanced anterior angles or the peduncle; width of elytra is 
greatest width; length of elytra, length from a transverse 
line tangent to the base to apex at suture, with the specimen 
in normal, flat position. 
Sloane’s revision of Australian Clivina appeared in 1896; 
his supplementary revision of certain groups, in 1904; and 
additional descriptions in 1896, 1907, 1916, 1917, and 1923 
(see references). These papers lay the groundwork for 
classiflcation of the Australian species of the genus, but 
much detailed work remains to be done. There is hardly a 
species which does not need to be redescribed and figured 
and its variations studied. Two characters deserve special 
mention here, one because it has been overstressed by 
Sloane, the other because it has not been noticed enough. 
The transverse impression of the declivity of the prosternal 
process is not a trustworthy taxonomic character ; the 
impression is sometimes both present and absent in different 
specimens of series of single species from single localities. 
The inner or flying wings, supposed by Sloane (1896, p. 145) 
always to be present in Australian Clivina, are actually 
vestigial in some of the species, including one of the new 
ones described below. Dimorphism of inner wings may occur 
too, but has not yet been demonstrated in any Australian 
species of Clivina. 
The new species of Clivina here described have been 
checked not only against the collection of the Museum of
