In No. 4 of this series of papers the only beetle recorded from Pearson 

 Island was Saragns oleatus, Carter (^^; the special visit to the island in January 

 of this year enabled more species to be taken (for notes on this visit see ante, 

 p. 97). The most interesting species obtained was a new Mandalotus, which 

 at the request of Prof. F. Wood Jones I have pleasure in naming after Sir George 

 Murray. 



CARABIDAE. 



Scop odes sigillatus, Germ. Simodonfus australis, Dej. 



TROGOSITIDAE (?). 



Phycosecis algarum, Pasc. (PI. xxxi. fig. 1.) Several specimens were 

 obtained on the island; the species is common on the beaches of New South 

 Wales and Tasmania. The derm of the head is usually black, the other parts 

 are usually pale castaneous, but vary to black ; the upper-surface is clothed with 

 scales that are normally snowy-white, but there is frequently a large median 

 blotch extending from apex of prothorax to beyond the middle of elytra, which 

 is stramineous or pale brown ; the elytral punctures are normally concealed, but 

 are indicated through the clothing; there is a beautiful fringe of long silvery 

 hairs on the prothorax and elytra. Specimens, however, are very easily damaged, 

 the scales and fringes are often partly abraded, and the scales are easily stained. 



LATHRIDIIDAE. 



Corticaria adelaidae, Blackb. 



SCARABAEIDAE. 

 Pseudopimelopus lindi, Blackb. 



BUPRESTIDAE. 

 Germarica casnarinae, Blackb. 



ELATERIDAE. 



Two specimens of this family were obtained ; one of a species too near the 

 description of Cardiophorus octavus, Cand., from the Swan River, for it to be 

 described as new ; the other a small Monocrepidius, which cannot be satisfactorily 

 dealt with at present.
