This is a very peculiar insect, occupying a rather isolated position amongst its 
relatives, which are the Western Mediterranean genus Amphiestris and the 
Siberian Onconotus. The male is unfortunately unknown, but there is no doubt 
that it has the elytra more developed than the female, and transformed com- 
pletely into a sounding apparatus ; it is not impossible that its pronotum is also 
modified. I do not know any other records of Orthoptera from such an extra- 
ordinary high altitude as this one.
