the longitudinal wrinkling of the ventral segments is more con- 

 spicuous. The " height " of the body (as defined in the description 

 of A. tardus) does not exceed a third of the length. 



The perfectly unicoloroiis dark blackish-green colour of the 

 upper surface is quite identical in the three examples before me, 

 and in itself distinguishes this species from any other known to 

 me. The colouring of A. bicolor, Fab., must be somewhat similar, 

 but that species is said to be " aeneous " on the upper surface ; the 

 present species is not at all so. Unless the type can be referred 

 to, A. bicolor cannot be positively identified as the description is 

 quite insufiicient. 



The mandibles are those of an Ainarygmics, but the facies is 

 entirely of Chalcojjterus.

POROPTERUS PRODIGUS, Pasc. 



There is nothing in the description of this species to distinguish 

 it from P. (Acalles) conifer, Er. If the two are distinct (as 

 seems likely enough from the wide divergence of their localities, — 

 Eclipse Island and Tasmania) they must be very closely allied. 

 The description is in both cases fairly detailed; but I can find no 

 point of diflference whatever. 



LONGICORNES. 



Tritocosmia digglesi, Pasc. 



This species appears to be identical with T. atricilla, Newm. , 

 described nine years previously.

AULACOPHORA AUSTRALIS, Blackb. 



I have come to the conclusion that this insect is a variety of 

 A. analis, Weber (described from Sumatra). I think the var.
