Subfamily Eurybrachydina, Stal. 



Euryhrachydida, Stal, Hera. Afric. iv, p. 129 (1866) : Eurybrachydina, Ofvers. 

 K. V.-A. Forh. p. 753 (1870). 



Anal area of wings very rarely reticulate, wlien so, clypeus convex 

 without lateral ridges : last tibiae without a mobile spur at the apex. 

 Frons broad, transverse or almost equally long and broad, amplified on 

 both sides in a distinct angle : anterior feet compressed, more or less 

 dilated : anal area of wings sometimes reticulated (Stal). 



Stal distributes the genera included in this subfamily into two 

 great groups : — 



(1) those in which the eyes beneath are spinose. 



(2) those in which the eyes beneath are unarmed. 

 a. Genera furnished with eyes spinose beneath. 



L Wings less ample, not or scarcely broader than the tegmina : 

 head very broad ; antennae briefly cylindrical ; eyes beneath very dis- 

 tinctly spinose ; clavus very broad at the apex. 



A. Head very slightly prominulous before the eyes ; genae nar- 

 rower ; frons scarcely or only a little broader than the thorax ; last pair 

 of tibi^ 5- spinose : — E^lryhrachys^ Guerin. 



B. Head more prominulous before the eyes ; genee broader ; frons 

 distinctly broader than the thorax ; vertex scarcely or only a little shorter 

 than the thorax ; last pair of tibiae 6-spinose : — Messena^ Stal. 



II. Wings ample, broader than the tegmina. 



A. Vertex distinctly sinuate at the base : lateral angles of frons 

 much produced ; antennas briefly cylindrical ; clavus broad at the apex, 

 two longitudinal veins separated through their whole length : median 

 longitudinal area of wings dilated, furnished almost entirely with trans- 

 verse veins ; last pair of tibiae 6-spinose : — Thessitus, Walker. 



B. Vertex very slightly sinuate at the base or truncated : lateral 

 angles of frons somewhat straight, less produced than in Thessitus, Wsilkev : 

 clavus narrowly open at the apex, the longitudinal veins united nearly 

 in the middle ; wings without a dilated area. 



a. Head hardly broader than the thorax, vertex truncated at the 

 base ; second joint of the antennae very briefly subcylindrical ; last pair 

 of tibiae 5-spinose : — Loxocephala, Schaum. 



h. Head narrower than the thorax, vertex subsinuate at the base ; 

 gecond joint of the antennae subglobose : last pair of tibiae normally 

 4-spinose : — Nesis, Stal.
