Juga separated to apices; chitinized portion of wings narrowed very much from 
base to apices, or if not so the lateral margins of pronotum and of chitin- 
ized portions of wings are fringed with long hairs, the costa is rounded, 
without a longitudinal groove, or the hind tibia has 5 series of long spines. 
Lateral margins of pronotum and of chitinized portions of wings with long 
hairs; apices of chitinized portions of wings obtuse; hind tibia with long 
spines on antero-ventral, anterior, antero-dorsal, postero-dorsal, and postero- 
ventral surfaces; at least fore and hind femora without spines.2. Cydnoides. 
Lateral margins of pronotum and of chitinized portions of wings without long

* The term “Spiracles’” in this connection includes the true spiracle and the two 
sensory setigerous punctures, the ‘anterior spiracular puncture” referred to under 
Corimelaena being the true spiracle.
