*S. ma7-ginatus Sol. — I have neither seen the description, nor 

 any identified specimen of this. 



Notes on the Species in the Table. 



The species of this group are very difficult to separate by 

 literary means, and it is doubtful whether many of them should 

 not be considered as varieties only. For example, S. Lindi 

 Blackb., *S'. mediocris Blackb., *S'. Odervahni Pasc, diifer only in 

 characters of size, and small points of structure or sculpture that 

 might well occur in the same species, so far as I am able to judge 

 without a close examination of the types. 



S. latus Blackb. — A very distinct species, which I have from 

 Sea Lake, Victoria; form very globular, and with the costte 

 almost entirely broken up into nodules. 



The synonymy of S. levicostatus Macl., with S. interrnjjHis 

 Breme, is extremely probable from De Breme's description and 

 figui'e. I have cotypes of S. levicostatus Macl. 



a. cassidoides Boisd. = 6'. emarginatus Guer., a synonymy given 

 in the Munich Catalogue, but I have not met with the authority 

 for this. It is a relief to be rid of any Boisduvallian species. 



S. infelix Pasc, though near, is quite distinct from *S'. emargi. 

 natus Guer. The latter has a wide range, and is common at tlie 

 roots of plants near the ocean at Sydney, but is found in all the 

 Southern States to West Australia. S infelix Pasc, from Tas- 

 mania (Mr. Lea has recorded it, and has sent me specimens from. 

 King Island, Tasmania) is very distinct in the sculpture of its 

 prothorax. 



S. hicarinatus Champ. — I believe I have correctly identified 

 two specimens under this name, from Camoweal, ISTorth Queens- 

 land, and Tennents Creek, South Australia, respectively. They 

 correspond with the figure and description. The name, however, 

 is misleading, as the three costse on each elytron are quite distinct. 



.*>'. tricarinatns Blackb. — Specimens from Condon, West Aus- 

 tralia, agree with the description exactly. These specimens,
