FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
WITH DESCRIPTIONS OF NEW GENERA AND 
SPECIES. 
By the Rev. T. Buacksurn, B.A. 
[Read May 2, 1899.] 
XXV, 
STAPHYLINIDZL. 
PADERUS. 
The following two new species belong to the same section of 
the genus as ser alis, Guér., differing © an Simsoni, Blackb., 
Meyricki, Blackb., and sparsus, Fauv., by their well developed 
parallel elytra, and from er uenticollis, Germ. , by their subfiliform 
and comparatively slender antennz. They all differ from 
australis inter alia in not having in combination black legs and — 
testaceous mandibles; from Adelaide, Blackb., by much smaller 
size, apical ventral segments black, &c. As there are now, 
including these two, nine known species of Pederus from 
Australia it is perhaps desirable that a statement of their 
distinctive characters should be given in tabular form as follows: 
A. Apterous species, with the elytra very narrow at the base; eves very 
small. 
B. Elytra closely punctulate. 
C. Prothorax with strongly rounded sides,— 
almost subglobular ~ ... Meyricki, Blackb. 
CC. Prothorax much more elongate in form, its 
sides not much rounded a ... Stmsoni, Blackb. 
BB. Elytra sparsely punctulate . .. Sparsus, Fauv. 
AA. Winged species ; elytra normal* (if otherwise, - -- 
the eyes not particularly small). 
B. Hind body entirely rufo-testaceous_ ... . Adelaidw, Blackb. 
BB. Hind body with some or all of the segments of 
dark colour (piceous or black). 
C. Antenne long, robust, and apically dilated .... cruwenticollis, Germ. 
CC. Antenne notably more filiform and slender. 
D. Mandibles testaceous. ° 
K. Legs black ... ... australis, Guér. 
EE. Femora (except at apex) testaceous... tweedensis, Blackb. 
DD. Mandibles black. 
K. Apical part of antennz dark ... ... angulicollis, Macl. 
EE. Apical part of antenne testaceous ... Koebeli, Blackb. 
P. tweedensis, sp. nov. Alatus; testaceus, capite (mandibulis 
palpisque testaceis exceptis) et segmentis ventralibus 
* This provision is inserted on account of a statement of M. Fauvel that 
he has seen abnormal specimens of P. cruentecollis, Germ., which are 
apterous.
