MR. F. F. LAIDLAW ON 



thal^i 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 ; pteroytigma ahuost 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 of the abdomen measure 29*5 mm. 



Comparison ot" this specimen with Ris'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. superha Selys, from which species it differs in 

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

 appendages. My species, T. kirhyi., is unfortunately very im- 

 perfectly known, but on the whole the jn-esent specimen would 

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

 I think, be regarded as conspecific with it.

[I propose the following arrangement of the Oriental species 

 grouped under the Selysian genera Disparonenra and Caconeura 

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

 of retaining many of the species in the original genera : — 



A. Ac lies midway between ax\ and ax-z. 



a. Posterior lobe of protborax of female armed witb 

 book-like projections, 

 a. Ab meeting nerve descending from quadrilateral. 



i. Cui reaching binder margin of wings bej'ond 



balf tbe wing-lengtb C/?Zoroj^(?'?(ra Laidlaw. 



ii. reacliing binder margin of wings before 



balf tbe wing-lengtb Disparoneara Selys. 



/3. Vestige of Ab not meeting nerve (le>;cending 



from quadrilateral, or absent altogetber Caconeura Kirby. 



h. Posterior lobe of protborax of female simple Indoneura Laidlaw.
