biirchclli, I conclude that Blackburn was misled by the 

 malformation. 



(52) Is my conclusion from figures and descriptions. 



(53) (54) Common species that include all the names; 

 noted. 



(57) The synonymy of alacris, Kerr., with alternecosta,. 

 Thorns., has been published by M. Kerremans himself. A 

 co-type of quadrinotata , Blackb., in the South Australian 

 Museum shows the same insect. A species I often used to 

 find near Cook Biver, Canterbury (near Sydney). 



(58) The commonest insect of the whole genus, with a 

 corresponding variation, which I believe includes the names 

 given . 



(59) (61) I feel sure of the synonymy, from descriptions. 



(60) S. •equina, Blackb. Type in National Museum, 

 Melbourne, examined by me and found identical with type of 

 violacea, Macl. The suggestion of mine that cupreofiava, 

 Saund., was the same was confirmed by Dr. Ferguson. 



In the following tabulation an asterisk (*) is placed 

 against species unknown to me. This tabulation is put 

 forward with some diffidence, and is probably not without 

 error. The difficulties can be partly estimated by the follow- 

 ing statement of the uumbers of names so far catalogued : — 



No. of species in tabulation. No. of names catalogued.. 



A. S fir/ mod era 8 15 



B. Themognatha 69 121 



C. Castia'rina 241 386 



Total 318 522 



In other words that 204, out of 522 names, should be 

 either sunk as synonyms or treated as variations; a formidable 

 list with which to make oneself familiar. M. Kerremans gave 

 345 species in the Genera Insectorum, and I find that four 

 species were then omitted — viz., subpura, Blackb. ; tyrrhena, 

 Blackb. ; pallas, Blackb. ;. and erubescens, Blackb. If my 

 tabulation is correct there are thus 318 existing species, of 

 which 31 are here described as new. 



The species can be divided into subgenera as follows : — 



1. Elytra pitted with large fovea te pnnctures (also striate- 



punctate in cancellata, Don.) — a. stigmodeea, Eschs, 



2-4. Elytra .striated or striate-pnnctate, the intervals some- 

 times costate. 



3. Tarsal hooks lobed or toothed at the base — b. themo- 



gnatha, Sol. 



4. Tarsal hooks simple — c. castiarina, C. and G.
