with dull red apical margin, third with broader red margin, fourth red clouded with 

 dusky- tiftK and sixth more strongly clouded ; venter clear red except base and 

 apex. 



Armidale. N.S.W., 5-2-15 (Dr. A.J. Turner). This is structurally allied to 

 E. diversipes. I cannot refer it to any described species. 



Exoneura abstrusa n. sp. 

 Male. Length about 6-5 mm. ; head, thorax, and abdomen black ; knees, 

 anterior, and middle tibiae, and anterior tarsi reddened, the anterior tibiae clear light 

 ferruginous, with a large elongate black mark basally on outer side, middle tibiae 

 much more obscurely coloured, with a larger black mark ; head and thorax with 

 rather long thin pale hair, tinged with brownish dorsally ; eyes very large ; clypeus 

 (except a small spot on each side of middle), labrum, and linear lateral face-marks 

 clear ivory-white, the face-marks diverging from the clypeus at the lateral spots, 

 and ending very acutely some distance below level of upper margin of clypeus, 

 which is straight ; antennae black ; tegulse very dark-brown ; wings hyahne, faintly 

 dusky, stigma and nervures dull ferruginous ; anterior and middle tibiae and tarsi 

 slender, but their femora stout ; hind femora rather robust, with much w^hite hair 

 beneath ; hind tibiae claviform, very broad apically, hind basitarsi very thick ; 

 abdominal venter reddish. 



Brisbane, Q., 8-2-16 (Hacker). One male. Very distinct among known males, 

 and apparently not to be associated with any described female. 



The males of this genus show remarkable differences. In such species as 

 E. nitida the general appearance is more like that of a female ; the face is not hairy, 

 the eyes are not remarkable, and the legs present no unusual features. In contrast 

 with this, E. diversipes has a narrow face with much long erect black hair, enormous 

 eyes converging below, and greatly modified legs with slender femora. Such insects 

 seem so far apart as to be hardly congeneric. E. abstrusa, however, is intermediate, 

 and the females seem all to be strictly of one genus. 



The above species of Exoneura may be separated by the following table. The 

 distinction between those with red and black abdomen becomes obscure in certain 

 members of this series, so in order to avoid any chance of error, I have repeated 

 them under both categories : —
