762 AUSTRALIAN AND TASMANIAN PSELAPHIDiE, 



Readily distinguished from all previously described species by 

 the conspicuous fovea on the undersurface of the eleventh joint. 

 The impressions on the ventral segments are so feeble that from 

 most directions they appear to be absent. The spur of the hind 

 tibise is so placed that the apex itself appears to be wide and 

 triangularly notched. The elytra are shorter even than in P. 

 mirandiis P. armatus, described as having shorter elytra than 

 in P. Victorice, has the metasternum and abdomen very different. 



Palimbolus dimidiatus Raffr. 



Only the female of this very distinct species was known to 

 Raff^a3^ 



The male has the antennae slightly longer and more thickened 

 at apex than in female, but with the long basal joint no longer;, 

 the prothorax wider near apex and narrower at the base; the 

 undersurface with a strong impression from middle coxpe to apex 

 of abdomen; a strong obtuse median tubercle on each side of im- 

 pression on metasternum; an obtuse tubercle on each of the four 

 hind trochanters; and the hind tibiai curved, somewhat inflated 

 and pilose about middle, and thence to apex concave; at about 

 their apical third there is also a feeble spur, indistinct or invisible 

 from most directions.

Palimbolus VicTORiiE King. 



The species described by Raffray as probably P. Victorice is the 

 commonest of all the larger species of Pselaphidce occuri'ing in 

 moss in Tasmania; and the males are easily recognisable by the 

 undersurface of the apical joint of the antennae, four hind tro- 

 chanters, abdomen and hind tibiae. Raffray describes the hind 

 tibise as " posticis intus ante apicem calcare maximo, lato, com- 

 presso et laminato armatis " and his figure(These Proceedings, 

 1900, PI. X., fig.39) agrees with this description; but the spur is 

 not solid as it appears at first sight, and is really a compressed 

 fascicle of setae or hair, evenly truncated. When stuck together 

 by gum, however, it appears really solid, no matter how examined 

 with a pocket-lens.
