Australian and Tasmanian Cryptocephalides. 377 



Idiocephala albilinea, Saund. 

 Idiocephala marginicollis, Saund. « 



(Plate XXIII, fig. 53.) 



As noted in Masters' catalogue, Saunders described the 

 male as marginicollis. The species is fairly common in 

 early summer.

Idiocephala flaviventris, Saund. 



(Plate XXIII, figs. 54, 55.) 



Referred by Baly to Eu-phyma. The species occurs near 

 Sydney, but appears to be rare ; in all the specimens I 

 have seen there is a wide subtriangular black patch in the 

 middle of the metasternum. 



Idiocephala nigripennis, Baly. 



I have seen three specimens which I refer to this species ; 

 in only one of them, however, are the elytra black, and 

 even then with a bluish gloss ; in the other two the elytra 

 are decidedly bluish ; the scutellum in one is black, in the 

 others it is somewhat reddish. The species appears to be 

 distinct by its entirely red head, prothorax with wide and 

 pallid (almost transparent) margins, the surface sparsely 

 punctate, and the elytra with coarse punctures in distinct 

 series. 



OCHROSOPSIS VERMICULARIS, Saund. 



I have several species under examination which agree 

 fairly well with the specific description of this insect. The 

 specimens which I refer to the species, however, have the 

 scutellum very slightly longer than wide, the base slightl}^ 

 wider than the apex, slightly notched, and narrowly 

 bordered with black, and with the sides slightly incurved. 

 In Saunders' diagnosis of the genus Ochrosopsis the 

 scutellum is described as " subquadrate," but in the 

 description of vermicularis its shape is not mentioned. All 

 the closely allied species here noted or described, however, 

 except the above described ones, have the scutellum 

 decidedly transverse. 



Two of these specimens are from New South Wales
