somewhat triangular at the base, curved, narrowed 

 towards the apex, and bhuitly toothed there. l\alpi 

 longish. Antenn;e long and slender. The fore lobe of 

 the mesonotuni is largely raised and does not reach to 

 the middle of the mesonotum, which is depressed behind 

 it. Scutellum large, only slightly roundly raised. The 

 median segment is elongate, has a gradually rounded 

 slope to the apex and has no keels ; its spiracles are 

 oval and are placed be\'ond the middle, half-way between 

 it and the ajjcx in a hollow. Abdomen long and slender ; 

 the petiole long and slender, not curved at the apex, longer 

 than the second segment ; its spiracles small, round, and 

 placed shortl)' be}'ond the middle ; the gastrocceli are 

 small, indistinct. Legs long and slender ; the hinder 

 coxa^ large ; the tarsi spinose ; their claws long, curved 

 and thickened at the base ; the front tarsi are bent at the 

 base ; the fore calcaria curved, pilose. 



Unfortunateh" I have only a $ of this genus. In the 

 form of the abdomen it does not differ much from 

 Mesoleptus, but in other respects it differs completely from 

 that and from any known genus of the Tryphofiides. It is 

 undoubtedly nearly related to Balioia, as is shown by their 

 agreement in the form of the head, thorax, and legs, but 

 differs in the fore wings wanting the areolet.
