FURTHER NOTES ON AUSTRALIAN COLEOPTEEA 
TEXEBRIOXID^. 
Platydema. 
P. OBSCURA. sp.nov. 
Ovalis ; supra ni^ra, subtns picea, antennis, palpis pedibnsque 
sordide testaceis; capite maris inter oculos comubus 2 acuminatis 
antice directis instructoj prothorace quam longiori plus duplo 
latiori ; elvtris puncrulato-striatis, interstitiis punctnlatis fortiter 
convexis. [Long. 2i, lat. lines (vix). 
Resembles P. teiraspilota in shape. The prothorax is quite tvrice 
and a half as wide across the base as it is long down the middle 
and has its front margin truncate or nearly so, its hindmargin 
strongly bisinuate ; it is margined all round, rather strongly and 
evenly narrowed from Ijase to apex with its surface moderately 
and rather closely punctured, and an elongate fovea running 
forward from the base on either side about halfway between the 
middle and the lateral margin. The horns on the head are not 
much shorter than that segment and viewed from the side are 
triangular, their upper outline r unning almost straight forward. 
The eyes of the example before me are of a testaceous colour. 
Resembles P. oritica, Pasc., in which, however, inter alia, the 
prothorax is said to be less than twice as wide as long. Also 
probably resembles P. Pascoei and laticoUe, Mad., (apparently 
described on females) ; it appears to be considerably larger t han 
the former and differently coloured, and to differ from the latter 
inter alia by its prothorax strongly bisinuated at the base. The 
other described species are veiy different. 
X. Territory of S. Australia ; collected by Prof. Tate. 
Trieolium. 
T. FERRUGINEUM, Fab. 
This species is not included in Mr. Master’s Catalogue; it is, 
however, plentiful, — doubtless introduced I have it from South 
Au.stralia and the Northern Territory.
