BUTLER, F.L.S., F.Z.S., Assistant Keeper Zoological Department, British Museum. [Received April 20, 1880.] (Plate XXXIX.) The very interesting little series of Lepidoptera which forms the subject of the present paper was collected by Major Howland Roberts at Rokeran, a small village only about six miles from Candahar, on the river Urgundab (or " Argandab " ) . Major Roberts writes (date 9th January, 1880) :- "I made no observation after the 2nd July, further than that I saw two species of Macroglossa, viz. stellatarum or one nearly allied, and one considerably larger. " After the beginning of April no rain fell; and when I arrived at Rokeran about the end of April the country was dried up, except where irrigation came into play and a few moist spots in the barren hills. The only plants that were green in these hills during the summer months were chiefly milky plants such as Euphorbia, and a few other stunted ones, but no trees ; consequently insects were comparatively rare. # " Along the dry bank of the river were little nullahs running into the river; these were kept moist from a small canal running above PROC.
