ABSTRACT. Twenty-eight moths, most of which are recorded from the U.S.A. or Texas for the first time, are illustrated. The text includes a brief description and distributional records known to the authors.

This paper reports 28 species of moths collected in Texas by the authors. In most cases, these have not been illustrated previously or have been mentioned only in publications that are now long out of print and difficult to obtain. The species were selected because in some cases they represent new U.S. records and are not included in the new Check List of the Lepidoptera of America North of Mexico (Hodges et al., 1983); in other cases, the species were included in the new check list based on the records given here, the specimens having been previously examined by the authors of the check list. Certain species were included because they represent important new range extensions. Finally, some represent species that have not been adequately illustrated previously. The authors hope that this information on striking and easily recognized species will be useful and that perhaps it will encourage others to develop an interest in this field of lepidopterology.

Sphingidae

Xylophanes libya Druce (Fig. 1). Hidalgo Co., Bentsen Rio Grande Valley St. Pk., 11-X-75, 1 male, E. Knudson coll. New U.S. record. Det. R. Hodges and V. Brou. This species is common in Mexico and has been collected there by the junior author within 200 miles of the border. The forewings are several shades of olive brown; hindwings are banded with black and dull orange yellow.
