The black spot on the elytra is sharply defined and very con- 

 spicuous ; it touches the apex in a point on the suture, thence its 

 outline runs in a sinuate curve forward and outward on either 

 side nearly to the lateral margin at a point considerably behind 

 its middle, whence it turns towards the suture parallel to the 

 base of the elytra to about the 5th stria, thence it runs up the 

 elytron (but obliquely towards the suture) to a point not very 

 much behind the middle of the same, and almost on the 4th 

 stria where it makes a round turn and runs obliquely down the 

 elytron to the suture. The prothorax, compared with that of 

 S. posticalis, Guer., is more transverse and less narrowed in front 

 and has the hind angles more rounded off. The black spot on 

 the elytra somewhat resembles in form that on the elytra of 

 S. corticalis, but is of less zigzag outline, extends much less 

 forward, and is very much more sharply defined and conspicuous.

COPTODERIDES. 

 Philophlceus eucalypti, Germ. 

 This species is unsatisfactorily treated by de Chaudoir in his 

 *'Mem.surlesCoptoderides," 1869. The description of it is limited to 

 the statement that it is very close to intermedius, Chaud., and differs 

 from the latter in a few specified characters among which the 

 piliferous punctures of the prothorax are not included. In inter- 

 medius they are said to be only two on each side. In describing 

 P. ohtusus the author states that " as in Eiicalypti " there are 

 only 2 piliferous punctures on either side, but a little further on 

 we are informed that P. planus^ Newm., has 4 piliferous punctures 

 on either side " placed as in Eucalypti.^'' As it is quite impossible to 

 make anything of de Chaudoir's remarks on this species, and as 

 there can be little doubt that a well known species occurring 

 commonly in many parts of S. Australia is that which Germar had 

 before him, I subjoin a description of this latter, which I am
