Of the series those from (Maniatoco are the largest, and those 
from Susumuco the smallest. The female from Honda shows 
decidedly the strongest intensification of coloration, with area 
between anal field and discoidal vein to median point on tegmina 
very heavily suffused with Itlackish brown. Every variation 
occurs to the more usual condition, in which the humeral trunk 
only, to opposite the apex of the anal field, is heavily suftused with 
blackish brown. 
Juveniles of this species have the occiput and inter-ocular- 
ocellar area dark Ijrown, rarely showing traces of buffy on the 
former and narrowly margining the eyes. Those of parabolicus 
are in general very similar, but have the occiput bufty in a usually 
extensive area, this color V)roadly bordering the eyes to the ocellar 
area.
