and iv. p. 98. 
I follow Stal in restricting this genus to £. longipes and its allies, these species 
having the anterior tarsi long, compressed, and claw-like, non-articulate, and biungui- 
culate. They are winged, and have the very long neck-like portion of the thorax 
formed entirely by the pronotum, this latter being extended backwards over the 
mesothorax in fully-developed specimens. The armature of the anterior femora is 
similar to that of Ghilianella. The head is without frontal spine.

tT The type of H. affints, Dohrn (in the Berlin Museum), a drawing of which is before me, is labelled 
“‘Veragua” : Dohrn merely gave “ Colombia”’ as the locality. It is without front legs.
