The strong bisiniiation o£ the base of the prothorax and the 

 evidently produced anterior margins of the elytra in this 

 insect are scarcely consistent with a place in the genus 

 3Ielohasis. There is, however, an approach to similar charac- 

 ters in M. speciosa, which certainly belongs to the genus, and 

 the general aspect of M. thoracia, structure of the apical seg- 

 ment, &c., are quite of the ordinary type. The lateral 

 serration of the elytra carried nearly to the base and the 

 shining iinpunctured space on either side of the metasternum 

 are also very distinctive characters. There is a very distinct 

 impression at the base of each of the intermediate ventral 

 segments on either side. 



I have a single specimen in my collection taken by myself 

 in South Australia, but unfortunately I have no exact record 

 of the circumstances of its capture. 



EIIETBIA. 



E. australis, sp. nov. Elongata ; cylindrica ; senea, vix cupreo- 

 tincta ; fortiter punctulata ; prothorace quam longiori 

 baud latiori ; elytris baud conspicue 4-costatis ; antenna- 

 rum articulo quinto sexto simili. Long. 4 1 . lat. 1 1. 

 The head scarcely differs from tjiat of E. chalcodes, Hope ; 

 the antennse are a little longer than in that sjDecies, the 

 series of dentate joints beginning with the fifth (not as in 

 JE. chalcodes, with the sixth). The prothorax is, by measure- 

 ment, equal in length and width, and is scarcely contracted 

 towards the front ; in other respects it hardly differs from that 

 of the older species. The elytra, however, are differently 

 sculptured. Outside the two costsB (which are really the 

 alternate interstices of an ill-defined system of punctured 

 striae) next to the suture, the striae (at least on the posterior 

 half of the elytra) become defined, and all their interstices are 

 convex, the alternate ones (representing the third and fourth 

 costae of E. clialcodes) being very little more so than the rest ; 

 the whole puncturation tends to run in longitudinal lines, and 

 the apex, which is feebly emarginate, has an obscure spine only 

 at the sutural edge of the emargination. The general form is 

 narrower and more cylindric than that of E. clialcodes, with 

 the elytra less pointed apically. 



Several specimens were taken by Mr. J. Anderson and my- 

 self about six miles from Port Lincoln. 



ANILAEA. 



This genus was formed by M. Deyrolle for the reception o£ 

 Antliaxia Adelaides, Hope. The truncate hind margin of its 

 prothorax, non-spinose apical ventral segment, and basal joint 

 of hind tarsi quite strongly compressed (on its wide face wider
