EXPLANATION OF PLATE XXXVIII (Unless otherwise indicated, the specimens figured are contained in the collection of W. J. Holland.) 17. Hemerocampa definita Packard, ♂, U. S. N. M. 18. Notolophus antiqua Linnæus, ♂, U. S. N. M. 19. 20. Hemerocampa vetusta Boisduval, ♂, U. S. N. M. 21. 22. Genus BEHRENSIA Grote Only one species has thus far been attributed to this genus. (1) Behrensia conchiformis Grote, Plate XXVIII, Fig. 44, 6. This little insect, which is as yet very rare in collections, is found in northern California and Oregon. Genus DIASTEMA Guenée (1) Diastema tigris Guenée. Syn. lineata Walker. The sole species belonging to the genus, which occurs within our borders, has been reported from Florida. We give in the ac companying cut an illustration of a specimen. which is found in the American Museum of FIG. 149.-Diastema Natural History. Genus OGDOCONTA Butler tigris. (1) Ogdoconta cinereola Guenée, Plate XXIX, Fig. 1, 9. Syn. atomaria Walker. This is not at all an uncommon species in the Atlantic subregion. I have found it particularly abundant in southern Indiana, where it comes freely both to light and to sugar. Genus PÆCTES Hübner Eight species are enumerated as belonging to this genus in Dyar's recently published Catalogue. Of these we have given illustrations of three in our plates. (1) Pæctes abrostoloides Guenée, Plate XXIX, Fig. 3, 9. The insect occurs in the Atlantic States, and ranges westward into the Mississippi Valley. (2) Pæctes pygmæa Hübner, Plate XXIX, Fig. 2, 8. This is a southern species. The specimen from which the figure on the plate was taken was captured in Texas. (3) Pæctes oculatrix Guenée, Plate XXIX, Fig. 4, 8. The species is by no means very common. It has a wide range from the Atlantic into the basin of the Mississippi. The specimen figured on the plate was taken in western Pennsylvania. I have specimens from Indiana and Illinois. Genus EUTELIA Hübner (1) Eutelia pulcherrima Grote. Syn. dentifera Walker. The only species of this genus known to occur within our territory is that which is figured in the accompanying cut, which FIG. 150.-Eutelia pulcherrima, . . was made from the type now in the possession of the British Museum. The insect is found in New York and New Jersey, but probably has a wider southern range. It is as yet very rare in collections. Genus MARASMALUS Grote (1) Marasmalus inficita Walker, Plate XXIX, Fig. 6, 3. Syn. histrio Grote. This species is found from the northern Atlantic States and Canada southward and westward to Texas and Colorado. (2) Marasmalus ventilator Grote, Plate XXIX, Fig. 5, . This species, which is considerably larger than the preceding, has the wings more or less marked by reddish scales, which enables it to be easily discriminated from its congener. Its range is practically the same. Genus AMYNA Guenée (1) Amyna octo Guenée, Plate XXIX, Fig. 7, 9. This little moth has suffered more than any other known to the writer by being made the sport of the makers of synonyms. No less than nineteen synonyms have been applied to it in addition to its true name. In Dyar's Catalogue it appears under the name orbica Morrison, and tecta Grote is given as a synonym. The student who wishes to know what some of the other names are which have been given to it may consult Hampson's "Moths of India," Vol. II, p. 251. It is found throughout the hot lands of both hemispheres. |
