has been recorded in the paper. The remainder of the paper contains de- 

 scriptions of new species of Tenebrionidae , and a description of one new 

 species of the Genus Stigmodera (Family Buprestidaej found (and so far 

 recorded only) from Mount Kosciusko. - — 3) Descriptions of new Species of 

 Australian Coleoptera. Part III. By Arthur M. Lea. — The paper contains 

 descriptions of 22 new species and one new genera (a blind one) of Staphy- 

 linidae, a new genus of Paussidae, a remarkable new genus of Ptinidae, 

 the only known species of which occurs in ants' nests, ^Ti.Inopeplus^ aPelonium 

 (a genus of CI erida e not hitherto recorded from Australia), four species of 

 Lathridius, and a very beautiful Lemodes. Several introduced species belonging 

 to the Lathridiidae, Ptinidae, and Cioidae are recorded, and a plate 

 of 9 figures is given. — 4) New Australian Species of the Family Agrionidae 

 [Neuroptera: Odonata]. By R. J. Tillyard, B. A. — Eleven new species 

 are added to the Australian list, bringing the total for this family up from 

 twenty-eight to thirty-nine. Seven genera are represented, of which two have 

 not before been recorded for Australia. Of the species described, ten are new 

 to science, and the eleventh has only been recorded befor from Central Africa, 

 where it is common. The species are apportioned as follows: two each to 

 Lestes, Älloneura, Pseudagrion and Agrioenemis, and one each to Agriolestes^ 

 Geriagrion and Ischnura. In two cases the females are not yet known. All 

 the new species come from Northern Queensland, mostly from the Cairns 

 district, and several exhibit very close affinities to species found in Java, 

 New Guinea, and the Solomon Islands. — Mr. David G. Stead exhibited 

 examples of the common »Freshwater Perch« of the eastern rivers of New 

 South Wales^ which though so common and so widely known as a valuable 

 game-fish, he considered to be new to science. On account of its purely 

 fluviatile habitat, Mr. Stead proposed for it the name oi Percolates fluviatilis. 

 The structural features at present chiefly relied upon for the diS'erentiation 

 of this form from its ally P. colonorum (Estuary Perch) are as follows : — 

 a) The far more elongate habit, b) The non-excavate character of the upper 

 profile of the head (which in P. colonorum is invariably concave — often 

 highly so), c) The relatively greater general thickness as compared with 

 body-height, d] The shorter head, e) The much more ctenoid character of 

 certain body scales in all but older specimens. It was also pointed out that 

 the habits of P. fluviatilis were difi'erent from those of P. colonorum. Mr. 

 Stead stated that he considered that none of the names now taken as syno- 

 nyms of P. colonorum were applicable to this form. Specimens of P. colo- 

 norum for comparison with those of the new species were also exhibited.
