Genus BELLURA Walker We cause this genus to be represented by a figure of the species named gortynides by Walker. Synonyms are densa Walker, vulnifica Grote, melanopyga Grote. The insect is peculiar to the Atlantic States, so far as is known. The cut was drawn from a specimen in the American Museum of Natural History in New York. Genus SPHIDA Grote (1) Sphida obliqua Walker, Plate XXV, Fig. 36, female. Syn. obliquata Grote & Robinson. The range of this moth is from the Atlantic to the Mississippi. The specimen figured was taken by the writer at light in Minneapolis. It feeds in the stems of Typha latifolia. Genus NONAGRIA Ochsenheimer A rather small genus of obscurely colored moths, the larvae of which burrow in the stems of aquatic plants, below the water-line. The genus is represented in both hemispheres. Six species belong to our fauna. (1) Nonagria oblonga Grote, Plate XXV, Fig. 33, male. (The Large Nonagria.) Syn. permagna Grote. This is a Southern species, thus far only recorded as found in Florida. (2) Nonagria subflava Grote, Plate XXV, Fig. 34, female. (The Yellowish Nonagria.) The insect ranges from Maine to Illinois, where it is found in the vicinity of lakes and pools of water in which rushes grow.
