spots one at vein 5 the other near anal angle. Hindwings fulvous brown, 

 with oblique white medial band not quite reaching costa.and terminating 

 near anal angle, narrowing at the dorsal part, this band as well as those 

 of forewings are blackish bordered, that of the hindwing most distinctly; 

 cilia white, dark brown at base, except a spot between veins 5 and 6, 

 which is white to the base. 



This species is closely related to our Omiodcs species. It is a 

 widely distributed species, occurring in Asia, Africa, and 

 Australia. It is very al)undant in the Hawaiian Islands. The 

 caterpillars feed chiefly upon Pigweeds (one or more species of 

 Euxolus, and Portulaca oleracea) , often being so abundant as to 

 entirely strip the leaves from these common weeds over large 

 areas. Th(^y also feed upon garden beets, cockscomb, and other 

 cultivated and wild plants or weeds of the Amarantaceae and 

 C'henopodiaceae. The caterpillars feed on the under-side of the 

 leaves protected by a slight Aveb; being green, they are easily 

 hidden, somewhat resembling ribs of the leaf. The moths are 

 often so numerous in cane-fields where the above mentioned weeds 

 are abundant, that they may be mistaken for cane leaf rollers, or 

 other injurious moths. 



Life History 



The eggs are flattish oval about % mm. by 34 mm.; 

 finely reticulated and somewhat wrinkled and of an iridescent 

 greenish hue. They are deposited singly on the surface 

 of a leaf, usually beside a rib or vein, or in a groove produced by 

 a vein on upper surface of a leaf. They hatch in a few days, and 

 the caterpillars are full grown in about two weeks. 



Caterpillar.— (Plate IV, figs. 9, 10). Full-grown, 19 mm. 

 long, tapering towards the ends, the head quite narrow compared 

 with the middle of body; light green, turning rose-colored a day 

 or two before spinning cocoon. The head has some faint 

 brownish mottling, black ocelli, a tiny black dot on postero- 

 ventral angle; cervical shield has faintly black lateral margin, a 

 conspicuous black spot in each lateral lobe, a tiny dot behind 

 each spot, anterior part of lateral lobe has brownish mottling 

 similar to that on the head; two black spots on segment 3 larger 

 than those of cervical shield, these are tubercles ii. The tubercles 

 are arranged similarly but they are not so conspicuous as in 

 Omiodes. 



The pupa (Plate IV, fag. 11) is formed within a slight cocoon
