On May 24 A. obtained a stone-fly and twostone-fly exuviae, small may-fly larvae, a couple of species ofcaddis-worms, a galgulid (toad-shaped bug)—all similarin general appearance to forms in the eastern United States. On the same day some Ithomiine butterflies, Hymenitisoto (with clear transparent wings spreading two and one-eighth inches, whose margins and veins are blackish, andwith an oblique milky-white band and milky-white spotson the front wings) and Dircenna klugii (already mentionedin Chapter V) were found only in dark shady spots in thesewoods.

M. of May 30, in the same generallocality, and in bright sunshine on a road above TierraBlanca on July 12.
