 smd. Sf/ndesii'S cormi^itis (§ )are forms peculiar to this island. 

 Passalus -presents only one species, P. /ie.vajj/i^llu$ Jjaiv. {\\). 

 Of the family Melasoma (belonging to the Heteromerce) 

 but one insect appears ; it is 8'd2^]ia IcsvicolUs Fabr., of which 

 none but Fabricius (^) and Olivier {^^) make any mention, 

 I must therefore form it into a separate genus Saragus, A 

 genus described by Dejean as Cestrinus, is nearly related to 

 Ojpatrum, but separated from it again by its crippled (small) 

 wings, and a few other characteristics : two species of 

 Cestrinus appear both in Van Diemen^s Land and on the Con- 



The edge of the tip of the mandibles is not rimmecl, even in the largest specimens 5 

 'the wing-cases, as compared with the neck-plate are a little longer than in L. Latreil- 

 lei ; Mac Leay appears to have confounded both species with aurata and Latreillei 

 but Donovan's plate is very accurate. 



L. rutilans. Prosterni mucrone prominente, obtusiusculo, rubrocuprea, tlio- 

 race obsolete canaliculato. 



3Ias- — Subopacus, thorace crebrius subtDiusque punctato. 



Fern. — Nitida, thorace creberrime fortiterque punctato, elytris parcius subtiliusque 

 punctulatis. 



The mandibles as in the last species; the male is distinguished by its color, the female 

 ■by the scarcely visible punctm-es on the wing-cases, these are a little longer as com- 

 pared with the neck.

185-7, t. 20, f. 1. Lethr. ceneus Fab. Syst. El. I., 2, 2, from Norfolk Island : with the 



exception ot the spined thig-h it appears to resemble naostly the following species ; it 



resembles this also in the structure of the mandibles (compare Scln-eib. a. a- 0. 1. 19, f. 1-3. 



. * Tertniaation of one spine of the front thig'h of the male knife-shaped. 



L.viridis (n. sp.) Prosterni mucrone rectetruncato,viridis,nitidula. 



Mas — Thorace vage subtiliter punctato. The hmder thighs have also a different form 

 from those of other Lamprimee ; they are rather longer and thicker, but equally thick 

 throughout, whereas in other Lamprimee the point is somewhat broad. A second 

 species of this division would be L. Micardi Reiche (a. a. O ) 



L. pyrfmma Machesij, a., a. O. 101-4, is perhaps an eighth species, unknown on the 

 Contuient : it belongs probably to the first division,
