842 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



wide as the front margin, the sides being very gently arched ; the 

 striae on either side of the disc are extremely fine and very close 

 together, the external one scarcely continuously traceable ; the 

 punctures on the disc are fine and moderately close, with a little 

 tendency to a longitudinal serial arrangement. The sculpture of 

 the elytra scarcely differs from that of the preceding species 

 except that the 7th interstice is costiform, whereas in L. difficllis 

 it is scarcely so. The scutellura is rather strongly transverse. 

 The antennte in both the specimens before me are very stout and 

 reach back a little beyond the base of the prothorax ; their joints 

 diff"er inter se very little in respect of width, the 1st being a little 

 wider than the 2nd, and the second slightly wider than the next 

 6, the 9th and 10th a little widest of all, the 11th rather elongate. 

 Allied to L. bistriatus, Gronvelle, but difiering in the much 

 closer puncturation of the prothorax, the grooved forehead, ifcc, &c. 



LAMELLICORNES. 



BOLBOCERAS KiRBII, Westw. 



In Mr. Masters' "Catalogue of Australian Coleoptera " this 

 appears as a distinct species. Prof. Westwood, however, in a 

 note to his description of it states that after his description was 

 in type he became possessed of evidence that it is only a variety 

 of B proboscideum, Schreibers, — and I believe his opinion has 

 not since been controverted.
