450 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



as long as wide and has gently arched sides, its greatest width 

 being just in front of the middle. 



Compared with L. grandis, GylL, this species is considerably 

 smaller and very much less dilated behind ; its antennee are much 

 shorter and stouter ; its prothorax and head are a little more 

 coarsely and rugulosely punctured, and the same coarse rugulose 

 sculpture extends over its elytra ; the apical joint of the palpi is 

 less strongly securiform ; the tarsi are more slender, with the 

 penultimate joint not so much wider than the preceding joints, the 

 ventral segments are much more strongly punctulate, and the 

 eyes are more prominent and more strongly granulated. 



A specimen in the South Australian Museum which I believe 

 to be L. cyaneay Macl., has a shorter prothorax and less rugulose 

 puncturation, besides being very differently coloured. From the 

 brief description of L. affinis, Boisd., that species would appear to 

 have the prothorax and elytra dissimilarly punctured, and the 

 expression "geniculis nigris" would seem to differentiate it from 

 the present insect. The three species described by Sir VV. 

 Macleay from Cairns all differ widely in colour and other 

 characters. L. tomentosa Fab., also is very different.

I have to acknowledge and correct an unfortunate error in my 

 notes on this genus published in the Proceedings (2), Vol. III. 

 part 4, pp. 1456-63. At the time I was unable to refer readily 

 to the description of T. hamata, Newm., and accepted without 

 verification the assertion in Mr. Masters' " Catalogue of Aus- 

 tralian Coleoptera " that that species and T. long/ijjennis, Hope, 

 are identical. I have since had reason to conclude that this is 

 not the case — indeed, judging by Hope's description, his insect is 

 as unlike hamata as could well be. The result of this oversight
