C^NOPSEN, gen. nov. 



? . Comes nearest to Psen, with which it agrees in the 

 neuration of the wings and in the form of the abdomen, but 

 may be readily known from that genus by the second joint of 

 the antennai (pedicle) being not small, but as long as the 

 third joint ; the antenna? themselves are longer, more slender, 

 and not dilated towards the apex, resembling more those of a 

 male than of a female. 



Antennai distinctly longer than the head and thorax 

 united; all the joints elongate; the scape as long as the 

 second joint, slightly curved. Eyes large, reaching near to 

 the base of the mandibles, parallel on the lower half; the 

 ocelli • . • Clypeus roundly convex, its apex transverse and 

 depressed in the middle. Labrum small, rounded. Man- 

 dibles ? Parapsidal furrows obsolete. Base of median 

 segment depressed, the depression clearly defined, striate i, 

 the rest of the segment irregularly reticulated. Tarsi pilose, 

 without spines, the base of the anterior roundly incised ; the 

 anferior spur curved, bifil at the apex ; the outer spur of the 

 posterior curved, dilated at the base, the inner spur shorter 

 and narrower. Anterior wings with three transverse cubital 

 nervures ; the first recurrent nervure is received in the basal 

 fourth of the cellule, the second is interstitial. In the hind 

 wings the transverse anal nervure is received beyond the 

 cubital. Abdomen with a long curved petiole, which is as 

 long as its dilated apex and the second segment united ; the 

 apical ventral segments are fringed with stiff hairs, and more 

 particularly the fourth. Pygidial area smooth, keeled late- 

 rally. 



The head behind the eyes is obliquely narrowed and is there 

 nearly as long as the eyes ; the occiput is sharply margined. 

 The antennge are placed ojjposite the middle of the eyes; 

 between them is a short distinct keel, narrowed at the top 

 and bottom ; the coxae and trochanters of moderate size ; the 

 niesosternum furrowed down the apex ; the tubercles are 

 large and are placed distinctly in front of the tegulee ; the 

 eyes have a narrowed but distinct furrow surrounding them ; 

 tlie episternal furrow on the mesopleurse is distinct, wide, and 

 deep ; the pronotum is clearly separated from the mesonotum j 

 the scutellum and postscutellum large, not much raised.
