The Secretary read a letter from Mr. C. A. Wilson, a Corresponding Member of 

 the Society, which bore date Adelaide, March 26, 1863, and contained a brief account 

 of the natural-historical results of the exploring parly under Stuart, which had recently 

 succeeded in traversing the Australian Continent from the South to the Norlh-West 

 Coast and back again. About fifteen hundred specimens of insects had been obtained, 

 but none of the Orders Orthoptera, Neuroptera, Diptera or Lepidoptera; many Lepi- 

 doptera were seen, including some butterflies of singular form and beautiful colouring, 

 but, owing to the accidental loss of all his entomological apparatus, Mr. F. G. Water- 

 house, the naturalist attached to the expedition, had been unable to capture any. A 

 few Hymenoptera had been obtained, and some Hemiptera, nearly all Sculelleridae. 

 In Coleoptera a new Cicindela, the first representative of that family in the South- 

 Australian province : upwards of fifty specimens were knocked down one damp evening, 

 about six hundred miles north of Adelaide ; the species was of large size, smooth, and 

 of a brilliant metallic green colour. There were a few new forms of Carabidae, and 

 many species of Dyticidae and Gyrinidae, evidently quite new. The South-Australian 

 species were generally unicolorous, but these were spotted or banded with difierent 

 colours. Of Staphylinidee or Paussidae none; of Lamellicorns but few; some of 

 Copris?; a few Cetoniae ; some large and handsome Buprestidae, probably new; and 

 many additions to Agrilus and the allied genera. There were many new Heteromera, 

 Curculionidae both large and small, and several distinct species of a genus with long 

 antennae, which was either curculionideous or was intermediate between the Curculi- 

 onidae and the Longicorns. Of the last-mentioned tribe there were also a few repre- 

 sentatives, principally Lamiae, which did not occur in any of the South-Australian 

 collections.
