in length, viz., Scaraphites crenaticollis — Mount GTambier, 

 Bremer, G-lenelg; and Sc. donastes — New Mecklenburg, Ard- 

 rossan), Calixia by fifteen, Philophlcms by twelve, Adelotobus 

 by six, Sylphomorpha by five, Pterostichus by four species. Other 

 genera again exhibit but one or two representatives, as 

 Catadromus (C. australis, the largest beetle of the family, 

 attains the size of one and three-quarter inches at Blanchetown, 

 River Murray ; while those captured at Lyndoch and Blumberg 

 are much smaller, and may be, though coloured similarly, a 

 distinct species). Other genera, similarly poor in species, are 

 Calosoma (two), Platysoma, Hell/us, and JSracMnus (each one). 

 The last is the curious Bombardier Beetle, emitting a small puff 

 of blue smoke several times in succession, with a perceptible 

 noise when approached by the hand. They were taken near 

 Lyndoch and Nuriootpa. In February last I met for the first 

 time, and in a single instance, with a species of Eudema at 

 Ardrossan, resembling a species from Queensland. Sorue other 

 genera, names unknown to me, make up the total given above. 



Of JNatatoees, the "Water Beetles, twenty-one species (not 

 including the largest of all, the gigantic Hydrophilus of Lake 

 Alexandrina) have been obtained, forming at least four genera, 

 viz., Dytiscus, four ; G-yrinus, two ; Hydrophilus, seven ; and 

 SydrocantJiara, eight species. The giant of the family measures 

 about two inches ; the smallest scarcely exceeds one-twelfth of 

 an inch in length. 



The Staphyliist, those curious beetles with shortened elytra, 

 are, except two or three species, generally very rare, showing a 

 total of twenty-six species in five or six genera. 



Proceeding to the Sebeicoenia, those Coleoptera which 

 exhibit more or less serrated or saw-like antennae, we find 

 them in plenty. They will be enumerated under five heads. 



The Moedellid^:, a family of small-sized beetles, living upon 

 the sweet juices of flowers, and whose last pair of legs is fitted 

 for leaping, furnish us with twenty-one species in two or three 

 genera. Some of the species are exceedingly numerous in 

 their season, every flowering Eucalypt or Melaleuca hiding 

 numbers of them. 



The Elateeedje are much more numerous in species than the 

 preceding, supplying a contingent of forty- two in, probably, six 

 or seven genera. All, with exception of one or two, are of 

 sombre uniform colour, ranging from light brown to jet black. 

 One species, not enumerated (because not in the collection), is 

 known by me to occur in the Barossa Banges. It is of small 

 size, but great beauty, the thorax of a bright red and the elytra 

 of metallic steel blue colour. The largest Elater, inhabiting 

 the Crawler scrub, is about one and three-quarter inches 

 long and three-eighths of an inch wide ; the next in
