Subfam. Stenocotinae. 



This s.ubfamily is characterized by the peculiar shape of the 

 vertex and by the ocelli being placed in cavities on the anterior 

 margin (viewed dorsally) of the head ; the posterior tibiae are 

 c[uadricarinate with 6 strong spiniferous spurs on the outer mar- 

 gin, shortly but strongly spined on the upper margin, and feebly 

 bristled on the others. 



Stal includes this in his heterogeneous Ledrina, the typical 

 form of which however has the ocelli on the disk of the vertex. 

 To the Stenocotinae belong Sfciwcofis Stal., and two new genera, 

 viz : Siiiicrocofis and Kyphocotis ; the general venation is that of 

 Ledra.
