258 REVISION OF THE AUSTRALIAN SPECIES OF ADELIUM, 



Tasmania), the so-called Adelium from New Zealand and New 

 Caledonia having markedly different characters. So far back as 

 1866 this was pointed out by Pascoe* when he formed the genus 

 Pheloneis for the reception of A. harpaloides White; at the same 

 time also he separated Seirotrana and Coripera from the true 

 Adelium. All three of these genera are differentiated from 

 Adelium by the character " Elytra prothoraci arete applicata," 

 while Pheloneis has the further distinction in "antennae articulis 

 apicalibus, ultimo excepto, transversis," and " tarsi antici et 

 intermedii articulis, ultimo excepto, plus minusve latioribus, et 

 triangulariter transversis." Considering therefore that Seirotrana 

 and Coripera are generally held by entomologists (I consider 

 rightly) as good genera (although the Munich Catalogue made 

 the mistake of confounding Coripera with Pseudhelops; and the 

 Supplementary Catalogue of Mr. G. C. Champion again merges 

 Seirotrana with Adelium) it is difficult to understand why Bates 

 should rename Pheloneis harpaloides as an Adelium] without 

 giving sufficient, or any, reason except that "Adelium is evidently 

 a polymorphous genus." 



Even if the genus Pheloneis be not accepted, as in my opinion 

 it should be, the New Zealand insects are much nearer Seirotrana 

 or Coripera than Adelium; while one species, A. auchlandensis 

 Broun, seems to be very near Licinoma. While in New Zealand 

 I captured some ten species of so-called Adelia, and identified 

 them from Captain Broun's excellent Catalogue. 



Blessig's memoir has supplied another character which is an 

 additional aid in the separation of Pascoe's genera from Adelium, 

 namely in the posterior intercoxal process being " abruptly 

 truncate." In some of the New Zealand insects there is some 

 modification of this, e.g., A. nigritulum Broun, and A. indagator 

 Broun, have this process moderately truncate (i.e., truncate with 

 slightly rounded angles), but in the narrow epipleurse, in the 

 position and structure of the coxae, and in the elytral sculpture
