384 Mr. A. M. Lea's Notes on 



median spot ; the latter is usually oblong-elliptic. There is 

 always a narrow black margin at the base of the elytra and 

 scutellum. The head varies from entirely black to entirely 

 reddish-brown, but is usually black, with a few indistinct 

 reddish-brown spots in the male, and reddish-brown with a 

 few more or less blackish spots in the female. In the 

 male there is usually a dark (sometimes quite black) stripe 

 on each side of the middle of the prothorax, the dark por- 

 tions being frequently confined to the two large tuberosities. 

 The intercoxal process of the abdomen is always paler than 

 the surrounding surface, and there is usually a transverse 

 black patch behind it. Tlie tuberosities on the elytra vary 

 considerably in number and elevation, and are usually 

 more clearly defined in the males, the largest one on each 

 is always granulate and close to the base. 



The antennae of the male if drawn back over prothorax 

 would pass the scutellum, those of the female if so drawn 

 back would scarcely reach the base of the median velvety 

 spot. In the male also the prothoracic tuberosities are 

 usually more pronounced and with a greater space between 

 them than in the female. 



Usually Tasmanian specimens are darker than those 

 from the mainland; those from Mt. Kosciusko, however, are 

 as dark as Tasmanian ones. On the elytra of specimens 

 from Tasmania and Mt. Kosciusko there is frequently in 

 both sexes an oblique slightly curved pale stripe. In the 

 elytra, however, there are frequently no distinct markings 

 to be seen, the surface being obscurely mottled ; in many, 

 however, there is a somewhat obscure pale triangular 

 patch on each elytron, the triangles approaching each 

 other at the suture slightly beyond the middle ; usually a 

 triangular space, at the sides of and behind the scutellum, 

 is darker than the rest of the elytra. 



A specimen from N. W. Australia is paler than usual 

 and with the median prothoracic marking reduced in size 

 and subtriangular in shape. 



Of the six species of Onchosoma described by Saunders 

 I am confident that Eivingi, dorsal is, Tasmanica,fovcicollis 

 and Tufcsccns should be regarded either as varieties or pure 

 synonyms oiferrugincus ; Klugii is distinct ; Cadmus vcr- 

 rucosiis, Chp., appears also to be only a variety of this 

 species, I have seen specimens of it from Mackay.
