When insect-hunting over some sandy ground at Botany about 

 the first week of last June I noticed the boring of lepidopterous 

 larvfe in the stem of ^ Dillwynia ericlfolia, and when pulling it 

 up to get this specimen I saw a large oval gall on the roots close 

 to the stem. Upon opening it I found it to consist of a thinnish 

 shell containing a perfect specimen of this beetle. 



Since then I have carefully hunted the same locality and have 

 found that nearly every bush of Dillwynia had its roots more or 

 less attacked by these beetles, some having as many as twenty of 

 the curious excrescences upon their roots. The galls are about 9 

 lines in length, 6 lines broad, 5 in depth, rounded on the apex. 



The larva is a whitish semi-transf)arent grub, consisting of 

 twelve segments, which are very distinct and almost globose in 

 shape, except the thoracic and anal ones ; mouth parts small. 



The perfect beetle is about the same length as E. affine, but is 

 much broader, the head and thorax bright bronzy colour, the 

 elytra much darker, marked with punctured striae, the minute 

 scales forming the scroll-like patterns of a silvery tint showing 

 out very distinctly on the apex of the wing covers. 



As far as I know this is a more common species than the last, 

 but it is evident that if one looks for the galls they are all 

 plentiful.

There seems to be some misapprehension about this species. 

 Saunders in his paper in Trans. Ent. Soc. 1868, p. 60, gives 

 Cisseis marmorata, L. and G., as a synonym of C. acuducta ; but 

 in his Catalogue of Buprestidse (1871) C. marmorata appears as a 

 recognised species, and E. marmoreum is given as a synonym of 

 C. acuducta. In Masters' Catalogue C. marmorata is omitted 

 altogether, and E. marmoreum appears among the synonyms of 

 C. acuducta. 



On the roots of several bushes of Dillwynia ericifolia pulled up 

 by me in the search for the galls of E. corpulentum, I found longer
