resembling in colour Elaphomia waUacei. The horns are 

 very remarkable, being suddenly dilated into a flat plate, 

 strongly toothed round the outer margin, and strikingly 

 resembling the horns of the elk, after which it has been 

 named. They are of a yellowish colour, margined with 

 brown, and tipped with black on the three upper teeth. 

 The fourth species (Elaphomia brevicornis, the short- 

 horned deer-fly) differs considerably from the rest. It is 

 stouter in form, of a nearly black colour, with a yellow 

 ring at the base of the abdomen ; the wings have dusky 

 stripes, and the head is compressed and dilated laterally, 

 with very small flat horns, which are black with a pale 

 centre, and look exactly like the rudiment of the horns of 

 the two preceding species. Xone of the females have any 

 trace of the horns, and Mr. Saunders places in the same 

 genus a species which has no horns in either sex (Ela- 

 phomia polita). It is of a shining black colour, and re- 

 sembles Elaphomia cervicornis in form, size, and general 

 appearance. The figures above given represent these 

 insects of their natural size and in characteristic attitudes. 

 The natives seldom brought me anythiug. They are 

 poor creatures^ and rarely shoot a bird, pig, or kangaroo, or 

 even the sluggish opossum-like Cuscus. The tree-kangaroos 

 are found here, but must be very scarce, as my hunters, 

 although out daily in the forest, never once saw them. 

 Cockatoos, lories, and parroquets were really the only
