of reach, much to our disappointment, as the under side of 

 these are Ukely resting-places for many sedentary forms of 

 micro-organisms. The patches of Ottelia were found to be 

 literally covered with a large pond snail, Limnaea, sp. The 

 quaint little Entomostracean, Bosmina, was present in 

 immense swarms, and the Rotifers Synchota and Euclanus 

 were also noted. During the examination of the collected 

 material it was noted that the cercaria of the liver-fluke was 

 being given off freely from many of the snails, while the 

 dissection of some of the snails in search of the rediae of the 

 fluke showed that every snail opened contained specimens of 

 the curious worm Chaetogaster. The rocks here were seen to 

 be folded into an anticline, and the quartz and mudstone 

 intimately associated. Some of this hardened rock contains 

 small cubical cavities, indicating the former presence of pyrites 

 crystals, which had been subsequently dissolved out. — F.

NOTES ON THE COLEOPTERA OF NORTH-WESTERN 



VICTORIA. 



Part VII.* 



By J. C. GouDiE. 



{Read before the Field Naturalists' Cluh of Victoria, 8th Sept., 1919.) 



A CONSIDERABLE time has elapsed since the last paper on this 

 subject appeared in the Naturalist. The delay, however, has 

 been more advantageous than otherwise, since a fair number 

 of additional species has been obtained during the interval. 

 Moreover, several valuable memoirs on Australian Coleoptera 

 have been published by various authors, and this has enabled 

 me to identify with certainty many species that would other- 

 wise have been excluded from the list. 



cucujiD^e. 



The Cucujidae are represented in this district by very few 

 species, all of small size and comparatively rare. They are 

 greatly depressed or flattened and more or less parallel in form, 

 with four- jointed tarsi and short antennae, and are found gener- 

 ally under the bark of trees or in ants' nests. 



Mr. Lea states that' the genus Nepharis " has been trans- 

 ferred from the Colydiidae to the Silvanides of the Cucujidae 

 by Mr. Grouvelle {An?i. Soc. Ent. Fr., 1912, p. 320), who also 

 proposed a new genus (Nepharinus) for N. goudiei."
