C. maculicollis* is closely allied to C. maculatus Macl.; while 

 C. globicoUisf is a thoroughly distinct species. 



I have recently described six new species, C. strigicollis, C. 

 quadraticollis, C. substrigos-us, C. cnrvipes, C. aureomaculatus, 

 and C. rectipf>s;l C. quadraticollis now proves, however, to be 

 synonymous with C. stp.rilis Pasc. 



In the present paper, seven new species are described, which, 

 with the elimination of synonyms and species removed to other 

 genera, make a total of twenty-eight species in the genus. 



Geographical Distribution. — The genus is almost universally 

 distributed in Australia, but is unrecorded from Tasmania. I 

 have never met with it in the Sydney district or on the Blue 

 Mountains; it seems absent from the entire area of the Hawkes- 

 bury Sandstone formation. On the western slopes and inland 

 plains, specimens of one or more species of Cubicorrhynchus are 

 plentiful, and are, indeed, very characteristic of the inland areas. 

 In South and Western Australia, it seems equally common. 

 The genus has not been recorded, however, from North Australia 

 or North Queensland, though it probably occurs in the inland 

 portions, but not in the jungle-areas. The dentate forms are 

 almost exclusively western.
