I am indebted to Mr. D. S. Fletcher for kindly responding to my inquiries about the Walker types and for lending specimens, and to Drs. C. W. Sabrosky and J. F. G. Clarke for conveying specimens to and from London.

TRANSFER OF CYMORIZA ABROTALIS WALKER, 1859, FROM
NYMPHULA SCHRANK TO DISMILILA DYAR
(PYRALIDAE: NYMPHULINAE, MIDILINAE)

Cymoriza abrotalis Walker (1859: 956) was described from a single male from Rio de Janeiro "in Mr. Fry's collection." Hampson (1897: 140) transferred the species to Nymphula, without comment. This placement was followed by Klima (1937: 92).
The holotype of C. abrotalis is in the Oxford University Museum. A photograph made by myself in 1958 (Fig. 1) shows clearly that the species is a midiline not a nymphuline, and that it belongs to the genus Dismidila Dyar. Although I had seen and photographed the type, I had not noticed the relationship and I omitted the name from my Revision of the Midilinae (Munroe, 1970). The maculation and wing shape show that the species is very close to Dismidila similis Munroe, type-locality Buenavista, East Bolivia, and to D. obscura Munroe, type-locality Petropolis, Rio de Janeiro State, Brazil. In colour it resembles D. similis more than D. obscura, but it has the hyaline spot of the fore wing much larger. In the absence of series and not having compared the types directly I think it better not to establish synonyms. I content myself with transferring the species to Dismidila as Dismidila abrotalis (Walker), new combination.

UNUSUAL COPULATORY BEHAVIOR IN THE NYMPHALIDAE AND SATYRIDAE

Interspecific, heterosexual coupling among Rhopalocera in the wild is relatively uncommon enough to warrant being recorded in the literature (Hovanitz, 1949; Shigeru, 1956; Stallings et al., 1959; Downey, 1962; Shapiro & Biggs, 1968; Perkins & Gage, 1970; Priestaf, 1970; Piatt & Greenfield, 1971). Even more rare are occurrences of intergeneric, heterosexual coupling (Frechin, 1969; Jae, 1972).
