var. apicifuscus, n. var. • 

 Two specimens from Karoonda to Peebinga (G. E. H. 

 Wright), and one from Mindarie (South Australia), have the 

 apical fourth of the elytra deeply infuscated (almost black), 

 they may be readily distinguished from the typical form of 

 macleayi by the basal angles of prothorax and by the front 

 tibiae. 



Phyllotocus, sp. 



An entirely pale specimen (from Edithburgh in the 

 Blackburn collection) combines characters of two species, as 

 the hind angles of the prothorax are rectangular as in 

 macleayi, and the front tibiae bidentate as in occidentalis. 



Phyllotocus marginatus, Macl. 



Specimens of this species taken on Stradbroke Island 

 (Queensland) by Mr. Hacker are smaller (5 mm.), than usual, 

 with part of the apex of the elytra black, and the pale 

 marking on the sides of the prothorax of the female smaller 

 than usual. 



Phyllotocus australis, Boi. 



Specimens of this species taken on Stradbroke Island by 

 Mr. H. Hacker, and at Cairns by Mr. F. P. Dodd, are 

 smaller (5*75 mm.) than usual, and with the pronotum, 

 scutellum, and elytra (except for a slight infuscation of the 

 latero-apical margins of the latter) entirely pale. 



Phyllotocus ustulatus, Blanch. 



The prothorax of this common Western Australian species 

 varies from entirely black (as on the type) to entirely reddish ; 

 several specimens before me have the prothorax reddish, with 

 three infuscated spots : a moderately long median one and a 

 small one towards each side. 



Phyllotocus navicularis, Blanch. 



In his table of the species of this genus Blackburn placed 

 navicularis in the firslt section "A. Elytra glabrous (or 

 nearly so) except along their lateral margin." But on many 

 specimens before me the hairs are quite as numerous about 

 the suture and base as on specimens of species he referred to 

 "AA. Elytra clothed with hairs (at any rate along the suture 

 and base)." 



The typical form has the head, prothorax, and a large 

 spot on each elytron black, the spots frequently have a 

 greenish or bluish iridescence, on the sides they occupy 

 about half the length ; along the suture they are conjoined for 

 about half their own length, being divided in front by a
