Gynandromorphs have been reported from many orders of insects and especially from those orders in which large numbers of individuals have been collected or reared. It is therefore not surprising that, with the accumulation of large scries, ephemerid gynandromorphs should be found occasionally and it seems advisable to put descriptions of such individuals on record. Needham, Traver, Hsu, etc.

The small group of the genus Ips placed at the end of Dr. Swaine's key seems to have a character not found elsewhere in the genus. The epistomal region, in the males, is elevated and often has a dense brush of hairs which make the elevation look greater than it really is. However, this brush is often rubbed until it has entirely disappeared. This has apparently given rise to the idea that two entirely different females are associated with the males in the same gallery.

Most of the records which follow are the compilation of field work during the period of September 1936 to September 1937 and the summer of 1938 while I was a member of the faculty of the University of Miami. Several able Orthopterists, particularly J. A. G. Rehn, Morgan Hebard, W. T. Davis, A P. Morse, and T. H. Hubbell have collected widely in southeastern United States, describing many new species.

The orthopterous fauna of this area of eastern Canada and of Newfoundland is exceedingly limited but at the same time is of considerable interest to those who are interested in the faunistics and ecology of this group.

In different regions of North America, Plebeius aquilo Bdv. varies considerably in size and maculation and appears to be differentiated into at least six geographical races. The distribution of each of these known races is roughly outlined in the accompanying diagram, and the localities marked are represented by specimens in the Canadian National Collection.

The Leng check list (1920) records under Scotochroa, which is a distinctly American genus established by Leconte in 1874, two species, S. atra Lec. and S. basalis Lec. Scotochroa buprestoides Kirby (described in 1837 as a Xylita) is listed under atra, indicating it as either a synonym or as being questionable as a valid species. The Csiki Catalogue of the Serropalpidae (1924) lists one species, atra, under Scotochroa with buprestoides given under this and with basalis as a variety. The Supplement of the Leng list (1927) records basalis as a variety of atra. The general question as to the species in this group seems to warrant a review of the genus with a key to the species.
