SUPPLEMENT TO "A CHECKLIST OF THE BUTTERFLIES OF GRANT COUNTY, NEW MEXICO AND VICINITY"1
Although drought conditions prevailed in the Southwest during much of the summer of 1976, some localities in the mountains north of Silver City, New Mexico received a moderate amount of moisture. The Burro Mountains and the high plateau areas such as L-S Mesa were very dry, but both Cherry Creek Canyon and the Mimbres River Valley supported fairly lush vegetation in July. On the east slope of the Black Range below Emory Pass, there was an especially good crop of wild-flowers along Highway 90. Butterflies were abundant about these flowers for the first time in a number of years. Many species were taken that had not been seen in Grant and Sierra counties for at least five years.
In April 1976, the author published a checklist of the butterflies of the Grant Co., New Mexico region (J. Lepid. Soc. 30: 38-49). This paper reported the results of 10 years of collecting. Collecting in July 1976 produced three species new to the area and a number of range extensions. The purpose of this note is to update the checklist published earlier. The list for this region now stands at 160 confirmed species with several additional sight records. Additional locality data were obtained for 48 species.
The locality alphabetic codes are those used in the original checklist and shown in Figures 1 and 2 of that paper. One additional code, MRV, has been introduced. This applies to the Mimbres River Valley from San Lorenzo to just south of Sherman. The three new species entries are preceded by an asterisk.
As in the past, the author's cousin, Ralph A. Fisher, Jr. assisted him in the field and he is responsible for many of the Sierra Co. records.
Hesperiidae-Pyrginae
Epargyreus clarus huachuca (Dixon). Grant Co.: SP.
* Erynnis lucilius afranius (Lintner). Grant Co.: BM, CCC, LR, SP. Sierra Co.:
EP. July. This species, which had not been seen prior to 1976, was quite common. Perhaps it was overlooked or mistaken in the field for E. persius fredericki H. A. Freeman, which is also common in the region. This species was confirmed by genitalic examination.
