The species Colias australis Vty. is recorded as a form of Colias hyale L. Pieris bryoniae O. is discussed as a subspecies of Pieris napi L.
In Rumania 44 species of the family Nymphalidae are recorded. In the introduction the author gives a short review of morphology and geographical distribution of this family. The immature stages, distribution, and variability of all species are discussed in more detail. Important are the morphological notes with good drawings. All species and some forms are figured in plates as black and white photographs.
Both books are of interest for all students of European butterflies.—J. Moucha, Prague, Czechoslovakia

FIRST MINNESOTA RECORDS OF THORYBES BATHYLLUS
Although recent popular literature lists the distribution of the southern cloudy wing, Thorybes bathyllus (Smith) (Hesperiidae), as westward to Wisconsin (Milwaukee) and Nebraska, Macy and Shepard (1941)1 do not cite any records for Minnesota. The southeastern corner of Minnesota, which is typically pseudo-Carolinian in its flora and fauna, provides good habitats for numerous "southern" species of butterflies. Unfortunately, a general lack of collectors has left as with very little knowledge of that area.
Recently, Ray Glassel donated to me the bulk of his butterfly collection and among these was a single specimen of Thorybes bathyllus, taken by him near Cedar Grove, Dakota County, Minnesota on 4 July 1960. I thought this to be the first Minnesota record, but a check of the University of Minnesota collection revealed one earlier specimen, taken at Mississippi Bluff, Houston County on 31 May 1942 by Morris Rockstein. Still another record appeared in the Season Summary (Lepidopterists' News, 1963, No. 4: 8); a specimen was reported from Houston County, Minnesota, taken on 30 June 1962.
These are the only known Minnesota specimens to date. Further collecting will probably find T. bathyllus in most of the southeastern corner of Minnesota where two of its foodplant species of Fabaceae, trailing wild bean (Strophostyles helveola), and small wild bean (Strophostyles leiosperma) are found.
