338 MR. F. F. LAIDLAW OX 



than 3-6. Bronze-black above, brownish white below. Anal 

 appendages (see text-fig. 4) brown tipped with black. 



Legs : grey-white, with black articulations and black lines on 

 the posterior surfaces. 



Wings : rather smoky ; pterostigma almost square, but its inner 

 margin more oblique than its outer ; dark brown, very finely 

 edged with lighter colour surrounded by a thickened black vein. 

 Px 15. 



Abd. 40 + '5 mm., h. w. 23 mm. 



Segments 3-6 ol' the abdomen measure 29'5 mm. 



Comparison of this specimen with Eis's figures and examina- 

 tion with his diagnostic table (Ris, Nova Guinea, xiii. Zool. 2, 

 pp. 100-102, fig. 22) has enabled me to determine that this 

 species is not T. superba Selys, from which species it diiTers in 

 its smaller size, absence of antehumeral stripes, and shape of anal 

 appendages. My species, 2\ kirhyi, is unfortunatel}'' very im- 

 perfectly known, but on the whole the present specimen would 

 seem to resemble it closely in colouring and venation, and it may, 

 I think, be regarded as conspecifi'c with it.

[I propose the following arrangement of the Oriental species 

 grouped under the Selysian genera Disparoneura and Caconeura 

 {AUoneura Selys). It is, I think, natural, and has the advantage 

 of retaining many of the species in the originid geneia : — 



A. Ac lies midway between axi and a.r-2. 



a. Posterior lobe of protliorax of female armed with 

 liook-Iike projections. 

 a. Ab meeting nerve descending from quadrilateral, 

 i. Cni reaching hinder margin of wings beyond 



half the wing-length Chloroneura Laidlaw. 



ii. Cuj reaching hinder margin of wings before 



half the wing-length Disparoueiira Selys. 



/3. Vestige of Ab not meeting nerve descending 



from quadrilateral, or absent altogether Caconeura Kirby. 



h. Posterior lobe of prothorax of female simple IndoHenra Laidlaw. 



15. Ac lies nearly at level of cm-, or proximal to it Eisioiieura Muii/,.
