second, and the other segments broadly testaceous ; the 

 testaceous colour more extended on the apical ones. 



Etha, ^^«. nov. 



Areolet quadrangular, large ; below scarcely angled ; 

 the transverse cubital nervures parallel ; the recurrent 

 nervure received in the middle ; the third discoidal cellule 

 elongate, its base two-thirds of the width of the apex ; 

 arched above ; the cubital nervure in its middle with a 

 short branch. Antennae longish, slightly thickened beyond 

 the middle ; the first joint of the flagellum distinctly longer 

 than the second. Eyes large, parallel, not reaching to the 

 base of the mandibles. Mandibles stout, with two large, 

 triangular, equal teeth on the apex ; the second joint of 

 the maxillary palpi dilated. Parapsidal furrows distinct. 

 Median segment large ; its spiracles linear ; there are two 

 transverse keels. Petiole narrow, curved, not much 

 dilated towards the apex ; its spiracles small, round, 

 and placed near the base of the apical third ; the second 

 and third segments become gradually dilated towards their 

 apices ; the other segments become gradually narrowed. 

 Legs longish ; the anterior slightly curved ; the tarsi 

 twice the length of the tibiae, incised at the base ; the 

 penultimate joint largely projecting at the apex beneath, 

 the projection ending in some stout spines ; the hinder 

 tarsi spinose, the penultimate joint ending, on each side, 

 in a bunch of long stiff spines ; the claws dilated at the 

 base ; their apex simple. 



The affinities of this genus are clearly with Ospyrti- 

 chohis, from which it may be known by the less elon- 

 gated face, by the shorter bidentate mandibles, by the 

 larger, more quadrate areolet, much longer third discoidal 

 cellule, through the cubital nervure originating nearer the 

 transverse basal, by the stouter, less elongated petiole ;
