behind ; but the difference is quite a trivial one. A difference in the widths of these 

 areas appears to be the only character in the least degree likely to be of importance 

 between L. macassariensis and L. papua as described by Kuwert.

The principal differences between L. novaeguineae and L. hansemanni , as des- 

 cribed by Kuwert, seem to be that the pronotum is somewhat less and the inter- 

 mediate areas of the metasternum are somewhat more extensively punctured in the 

 former than in the latter ; I do not think that these differences are very likely to 

 prove constant. It is impossible to tell with certainty from the structural characters 

 mentioned in Kuwert's descriptions whether L. batchianae , cicatrosus and consequens 

 differ in any constant character either from this species or from L. bicolor ; or whether 

 ribbei and geminatus differ in any constant character either from this species or from 

 L. dentatus. But the two last are much larger than any known specimen of 

 L. novaeguineae or of any of the forms I have identified with it ; so for the present 

 their names are best associated with that of L. dentatus. I have moreover, seen 

 specimens identified by Kuwert as L. batchianae and L. cicatrosus , all of which 

 appeared to meto beL. bicolor ; while a specimen identified by him as L. ribbei was 

 L. dentatus. It is possible, 1 think, that all the forms here grouped together as 

 L. novaeguineae, may ultimately prove to be identical with one or other of the 

 dominant forms dentatus and bicolor.
