Melolasis sordlda, Blackb.=J/. olscura, Saund (E.M.M., Dec. 

 1876). This change of name appears to be necessary, as the 

 name ohscura was applied by Hon. W. Macleay to another 

 species of the genus in 1872. The insect is evidently a common 

 one in South Australia ; I have many specimens before me from 

 Adelaide and Port Lincoln districts ; like others of its genus 

 it varies greatly in size (from 4 1. to 6 1.), and in colour from 

 an unicolorous coppery tint (with only the front of the 

 anterior legs greenish and the apex of the tarsi blue) to 

 coppery, with the head, front half of the underside and front 

 of all the legs bright green. 



M. cufreo-vittata, Saund. There is a nice series of this species 

 in the South Australian Museum. The size varies from 6 1. to 

 9 L, the ground colour of the upper surface from fuscous to a 

 bright copper color, and the spots and vittae on the elytra are 

 Tnore frequently bright green than coppery. The structure of 

 the apical ventral segment is very peculiar. In one sex the 

 excavation (usual in the genus) is extremely wide and deep, 

 and the anterior part of its margin is produced backwards in a 

 kind of tooth, so that the segment appears to be tridentate 

 apically ; in the other sex the incision is narrow, deep, and 

 with the anterior part of its margin rounded, and there is a 

 small notch on either side of the lateral margin of the segment 

 just before the apex.

 pubescentibus, illo fortiter sat crebre (abdominis seg- 

 mentis ultimis 4 subtilius) punctulato. Long. 6f L, lat. 2-yq 1. 

 This large and beautiful species is very distinct from any 

 other previously described ; its narrow elongate form strongly 

 pointed behind, and the margins of the elytra scarcely den- 

 ticulate except round the extreme apex, are conspicuous 

 characters. It should be noted that the anterior margin of
