Series 2. — Graphidineae. Apothecia seldom round, usually elongated- 

 ellipsoidal, no capittilium — 



Arthoniacese, Graphidiaceae, Rocellacege. 

 Series 3.— Cyclocarpinea. Apothecium usually circular, no capittilium. 

 (rt) Spores usually two-celled, either with a strongl}^ thickened 

 cross-wall often perforated by a narrow canal or with cross- 

 wall only slightly thickened. In the first case the spores are 

 usually colourless, the second case always brown— 

 Buelliaceae, Physiaceae. 

 (6) Spores unicellular, parallel-multicellular, or niuriform, usually 

 colourless, cross- walls usually thin, 

 (a) Thallus in moist state more or less gelatinous. 



Gonidia always belonging to the Cyanophyceae, Lichinaceae, 

 Ephebaceae. Collemaceee, Pyrenopsidaceae. 

 (6) Thallus not gelatinous. 



Coenogoniaceae, Lecideaceae, Cladoniaceae, Lecanoracese , 

 Pertusariaceae, Peltigeraceae, Stictaceae, Pannariaceae, 

 Gyrophoraceae, Parmeliaceae, Cladoniaceae, Usnaceae. 

 Basidiolichenes (Hymen- Lichens). 



Cora, Dictyonema, including Laudatea, Corella (doubtfully placed here, 

 as the hymenium is unknown). 

 Such is the Engler system, and it is favoured by many eminent 

 botanists. This will intimate to the lichenologist the way in which 

 modern thought is tending, and I would strongly recommend to every 

 student a careful perusal of Engler and Prantl's valuable work. 



NOTES OX THE COLEOPTERA OF NORTH-WESTERN 



VICTORIA. 



Part V. 

 By J. C. GouDiE. 

 {Read before the Field Naturalists' Club of Victoria, i^th Oct., 191 3.) 

 The last paper on this subject * concluded with an account of 

 the Scydmaenidge. We have now to pass over three families — 

 viz., Silphidse, Trichopterygidse, and Scaphididae — as being un- 

 represented (or at least unrecorded) in the insect fauna of the 

 Mallee. It is difficult to account for the absence of some of 

 these " missing links " from the entomological chain. For 

 example, the species of an interesting blind genus, Rodwayia, 

 of the Trichopterygidae, are found abundantly both in Tasmania 

 and New South Wales. They occur as inquilines in the nests 

 of several species of ants, at least one of which, Ectatomma 

 metallicum, is evenly distributed over the Eyrean sub-region, 

 of which this district forms a part. 



HESTERIDiE, 



This is a moderate-sized family, comprised in two groups — 

 the Hololeptides, typical species of which are broad and flat, 

 living under the bark of trees, &c., and the Histerides, recog-
