Prochalia pygmaea sp. nov. (PI. Ill, Fig. 5). $. Head, thorax, abdomen and wings uniform black-brown, much as in M. nigrita B. & McD. Abdomen extending slightly beyond margin of secondaries. Expanse mm. Habitat. Everglade, Fla. (May 1-7). i $. Type, Coll. Barnes. The sacks are narrow, cylindrical tubes of silk 12 mm. long, mixed with excrement and more or less covered with small pieces of lichen. They were not rare on the trunks of orange trees, feeding doubtless on the lichens which covered the bark; only one specimen was, however, successfully reared, this emerging after leaving Ever- glade. It is probably this species referred to by Hylaerts, (Bull. Soc. Ent. Belg., 1884, p. 209), as an unknown sack from Florida. COCHLIDIIDAE Prolimacodes scapha argentimacula subsp. nov. (PI. II, Fig. 2). Differs from typical scapha in having the silvery line from apex of wing closer to outer margin and the basal angle of same filled with silvery white, nearly as in trigona H. Edw. Habitat. Ft. Myers, Fla. (Apr. 16-23, May 1-7). 6 S- Type, Coll. Barnes. This constant form seems worthy of a varietal name; it probably represents a geographical Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illu
