70 REVISION OF THK AUSTRALIAN AM AUYCi.MIDKS, 



these characters, if not strongly develoi>c(l (with the exception of 

 that concerning the colour of the jtrothorax), are in the main the 

 characters that in Part I. of this memoir I have indicated as 

 ilistinguishing the male from the female, and as I am not sure 

 whether I sent to Mr. Champion a male, a female, or both sexes 

 of the insect which I take to be cupripeiuds, Hope, I shall 

 await further correspondence, with which 1 hope Mr. Champion 

 will favour me, btfore I regard the correctness of my identification 

 as disproved;* but I think it well to embody Mr. Champion's 

 observation in this memoir, so that thor.e who make use of the 

 memoir may be on their guard to rely on my description of the 

 insect rather than on the name, and to call it " Chalcopterus 

 cupripennis, Blackb. (? Hope)," for the present, and until a 

 further expiession of opinion from Mr. Champion, which I doubt 

 not that gentleman with his usual friendly courtesy will send me 

 in duo course, shall enable me to report to the Linnean Society 

 more definitely on the point. It is of course likely enough that 

 the "etc." at the end of ]Mr. Champion's note quoted above may 

 include characters that will be quite decisive. 



C, EXOLETUS, sp.no v. 

 C. difficili, Blackb., atfinis ; minus nitidus ; elytris (exempli 

 typici) purpureo, certo adspectu viridi-micantibus ; antennis 

 (S ^) apicem versus baud incrassatis, articulo 3° quam 4"* 

 5"^que conjunct! sat breviori, articulis 8-10 quam prsecedentes 

 nuUo modo brevioribus ; prothorace quam longiori (et postice 

 quam antice) dui)lo minimum latiori ; elytrorum puncturis 

 seriatis postice minus fortiter impressis. 



[Long. 7, lat. 4 lines. 



* In a later communication Mr. Champion expresses himself fully con- 

 vinced that the differences are specific, a determination which I regard as 

 conclusive. The insect that I have throughout this revision called 

 cnpri2'>en)ii-i, Hope, must, therefore, bear the name of aifini-^, Blessig, if I 

 am right in thinking that name to represent a mere var. of (7r/>?vjiK«»?'-s. 

 Blessig (nee Hope) ; it is with still greater certainty the species that Mr. 

 Pascoe described subsequently as ^4. Hou'lffi. It is undoubtedly, I think, 

 the insect that Germar and Blessig believed to be cuprijjennis, Hope. 

 Unfortunately, I followed them.
