fusco = "dark", can also mean "brown"
lineata = "lined"
limbata = "bordered"
saturata = saturated or suffused (with color)
io = can have different meanings in different contexts, and depending on
whether it is from a latin root or a Greek root.  However, here I
believe it is from Latin, and means "violet"

Therefore -
fuscolineata = "dark-lined"
fuscolimbata - "dark-bordered" or "dark-edged"
iosaturata = "suffused with violet"
iolimbata = "violet-bordered"
