Mesepimeron with a large patch of flat white scales

cinereus
20--Hind femora indefinitely pale beneath, legs otherwise

pale anterior stripes running the whole length; hind
tibia without an evident pale apical spot above but the
anterior stripe reaches the tip; costal and subcostal
veins with more or less numerous pale scales over the
basal -2/3 of the wing .......................................
Femora and tibiae either unstriped or, if stripes are

pre-alar scales present ........................ argenteopunctatus kingi
() Some specimens of C. p. quinque[asciatus with lighter scales over hind

of the associated male is perhaps the best way to ascertain the identity of such
palo females.
