(Plate XXV, figs. 136, 137, 157.) 



In this species and its varieties the dark parts of the 

 head and prothorax vary considerably in extent independ- 

 ently of sex, and specimens from Tasmania as a rule are 

 larger and darker and the markings greater in extent than 

 on those from N. S. Wales. 



The form described by Boisduval was without the yellow 

 elytral margins and appears to be rare ; Blackburn 

 (T. R. S. S. A., 1891, p. 139) records it from N. S. Wales. 



Co'i/ptocephalus tricolor, Fab. var. Suffrian (Linn. Ent., 

 1859, p. 101) says the supposed variety of ^n'co/or described 

 by Fabricius belongs to consoles. 



Idiocephala rod, Saund. This is the common form, 

 having, as described by Saunders, the yellow margins not 

 continuous to the apex of elytra, the scutellum black and 

 the femora black except at base. It was described origin- 

 ally as from the Swan River and Van Diemen's Land, and 

 is fairly common in N. S. Wales, Victoria and Tasmania. 



/. atripcnnis, Saund. A variety having the elytra black 

 and 3rd and 4th joints of antennse brownish ; it is appar- 

 ently a very rare variety and is unknown to me ; no locality 

 for it is given by Saunders. 



/. elegans, Saund. Described as having the scutellum 

 and femora pale and the external markings of elytra 

 almost continuous to apex. In a pair taken m cop. near 

 Sydney the male has the scutellum black and the female 

 pale but with dusky margins. 



LoxophiLrus plagicollis, Chp. This appears to be a 

 synonym only of the variety elegans. 



A variety, hitherto undescribed, of which I have a speci- 

 men from Sydney, has the scutellum and femora pale, the 

 lateral markings of elytra very narrow towards but con- 

 joined at apex, and the prothoracic blotch reduced to a 

 narrow brownish streak; the 3rd and 4th joints of its 

 antennae are paler than the others.
