broader, but No. 28, from Queensland, is by far the broadest. No. 24 is 0. hoh- 

 sonii, female, but differs but little from No. 25, which is a mainland specimen. 



This species is wide-ranging, but has not developed clearly defined races. 

 The name, 0. ministraUs hohsonii, may be retained for Tasmanian examples, 

 which appear to have the facial shield transverse.

Hah. New South Wales, South Australia, Central Australia, and Western 

 Australia. 



This species is distinguished by its slender pronotum and the orange fore- 

 margin of elytra. The male figured is from Adelaide, the female from Mount 

 Painter. We have nearly thirty specimens, which do not show any variation 

 towards the other members of the genus. 



ORTHODERA BURMEISTERI Wood-Mason.

Orthodera hurmeisteri Wood-Mason, Cat. Mant., 1889, p. 21; Orthodera longi- 

 collis Brancs., Jahresb. Nat. Ver. Trencs., 1897, p. 61, pi. i, fig. 6. 

 9 Allied to 0. 7ninistralis, but differs in being longer and more slender. 

 Head very similar, wider, vertex arched, eyes bluntly pointed ; facial shield with 

 corners rounded, ocelli less prominent. Pronotum long, margins nearly smooth, 

 pale silvery green, a median area reddish (in dried specimen). Wings long, pale 

 silvery green, hyaline, fore-margin of front wings reddish. Legs orange, anterior 

 femora with a green area on inner face. Length, 38 mm. 



Hah. New Guinea (Port Moresby, type) ; Queensland: Dalby (Mrs. F. H. 

 Hobler). 



Our single female agrees very well with the description of this species, which 

 was first recorded from New Guinea. The measurements given in the original 

 description agree, except that in the present specimen posterior femora and tibiae 

 are each 1 mm. shorter.
