NOTES ON AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES. By the Rev. T. Blackburn, B.A., Cork. Mem. Linn. Soc. N.S.W. Part V. CARABID.E. SiLPHOMORPHA AMABILIS, Cast. Among the insects taken by Dr. Bovill in the N. Territory of S. Australia is a specimen that seems to appertain to this species, though it is difficult to be quite sure as Count Castelnau's descrip-tion deals only with colour and markings. In respect of these the example before me shows the following discrepancies, — the prothorax instead of being "yellow with a large black spot occupying its centre " is black with the lateral margins broadly yellow and the front and hindmargins narrowly pitchy-red ; the base of the elytra instead of having " a black spot near the centre" is narrowly black on its inner half, with the black colour a little dilated at its outer extremity. The elytra are widely and feebly (but quite regularly and distinctly) costate, a wavy and very fine scratch-like stria running between each two costse. The species may be readily recognized by the remarkable resemblance of the black|^markings (excluding the narrow black edging of the apex), when viewed with the head towards the observer, to the figure of a tree, — the black front portion of the suture representing the trunk, and the mark that Castelnau calls a " black fascia" repre-senting the branches and foliage. SCOLYPTUS OBSCURIPES, Sp.nOV. Minus elongatus ; minus nitidus ; niger, antennis palpisque I'ufescentibus, tarsis ruf o-piceis ; menti dente lato triangulari lobis
