Odonata from Queensland. 17 



Fore wings witli ten to eleven antenodal cross-nervure.s, 

 the last not continuous, generally with pale spaces between ; 

 eight to ten postnodal cross-nervures ; pterostigma dark testa- 

 ceous or black ; triangle long, rather narrow, with three cross- 

 nervures, and followed by five or six cells, increasing ; two 

 supra-triangular ncrvures ; cells of the subtriangular space 

 numerous. 



IJah. Mackay, Queensland. 



Described from one male and four female specimens. 



Probably allied to R. regies and chalcoptilon, Brauer. Very 

 like R. cuprina^ Kirb., from Sierra Leone, in general 

 appearance.

Long. Corp. 12-14 millim. ; exp. al. 44-48 millim. ; long, 

 pter, \\ millim. 



Four specimens (three males and a female), almost precisely 

 alike, the opaque colouring in the fore wings extending only 

 just laeyond the nodus on the fore wings, instead of two cells 

 beyond, but ceasing five to seven cells before the pterostigma 

 on the hind wings, instead of only two or three, as in typical 

 resplendens ; the opaque part of the wing is shot with brilliant 

 blue in the males, more or less bordered with black ; in the 

 female it is cupreous, with the larger oval vitreous patch in 

 the hind wings covering rather more than three cells on each 

 side of the upper sector of the arculus ; the smaller patch only 

 covering part of one on each side of the nodal sector. 



IJah. Mackay, Queensland. 



De Selys noticed this form as a variety from a single male 

 in the collection of Mr. M'Lachlan. I have not thought it 

 necessary to give a detailed description, but think that the 

 constancy of the characters in the four specimens now received 

 entitle it to be considered distinct from typical resplendens^ 

 which the British Museum possesses from New Guinea. 

 There is also a female from Batchian in the Museum agreeing 

 with R. Turneri in the opaque part of the wing ceasing just 

 beyond the nodus ; but the opaque part ceases on the hind 

 wings four cells before the pterostigma, and the hyaline spots 

 are much larger and more conspicuous. This form was also 

 regarded by De Selys as a variety of R. resplendens^ but may 

 prove to be distinct when more specimens are obtained.
