Co2)era atomaria Kirby, Cat. Odonata, p. 129. 



Three females and a male, all immature, from Kwala Aring, in 

 September. 



The upper anal appendages of the male are fully one-half the 

 length of the lower pair. The second pair of tibias ai'e not 

 dilated, the third pair are unfortunately lost.

This species is one of the largest and in some respects the most 

 remarkable member of the " legion." It has previously been 

 recorded from Java and Sumatra, but apparently the appendages 

 of the male have not hitherto been described. These, it will be 

 seen, bear a closer resemblance to those of species belonging to the 

 genus A7nphic7iemis than to those of species of Teinohasis. 



The most striking peculiarity of the species, apart from its large 

 size and extremely slender proportions, is the pentagonal shape of 

 the pterostigma, most' mai-ked in the fore wing. The pterostigma 

 is brownish black with a lighter margin, the whole surrounded 

 by a thick black nerve. 



Another remarkable feature is the curious " horn " curving 

 upwards and a little forward from the middle of the hinder 

 margin of the prothorax. 



The upper pair of appendages of the male are rather slender ; 

 they curve inwards and a little downwards. They axe black at 

 the base, but for the greater part of their length dull yellow. 

 Each bears rather beyond its middle a small tooth on its upper 

 inner surface. 



The lower pairs are shorter and much slenderer ; they run 

 nearly straight back, converging slightly. Each at its extremity 

 meets the extremity of the upper appendage of its own side. 

 Coloration similar to that of the upper pair. Both pairs are 

 black at the tip. 



TeINOBASIS KIRBYI, Sp. n. 



A single male, unfortunately much damaged, from Gunong 

 Inas. As it is quite distinct from any described species, it is 

 well, I think, to desci-ibe it in spite of its mutilated condition. 



Length of hind wings 25 mm. 



Wings petiolated to the level of the commencement of the 

 quadrilateral. Claws smooth, without teeth. Inner margin of
