On Some Coccinellidae (Coleoptera) From Newfoundland and Nova Scotia

In 1949 and 1951, Dr. Carl H. Lindroth, of the Univer.sity of Lund, Sweden, and party made extensive collections of insects in Newfoundland, with some attention paid to Nova Scotia and Miquelon. The writer has been privileged to examine the lady-beetles collected by the members of the two expeditions, which were made possible by grants from the Arctic Institute of North America and the University of Helsinki, Finland. A total .of 348 specimens, representing 19 species, one of which appears to be new to science, was taken. The first set of specimens is deposited in the Helsinki University museum, the second (including the unique type of the new species) in the Canadian National Collection. Other specimens are in the collections of the United States National Museum, the Museum of Comparative Zo.ology and the writer. A list of the species taken, with localities, dates, collector’s initials and station numbers, is given at the end of this paper. The collectors were C. H. Lindroth and E. Palmen. The following species seem w,orthy of special comment. Coccinella undecinpunctata L. Known fr.om various stations along the Atlantic coast from Massachusetts northward. At this time it seems best to correct the record of this species from Alaska. Dobzhansky, in his revision .of North American Coccinella reported two specimens from Alaska as belonging doubtfully to this species. Dissection .of one of them, a male, showed them to be C. difficilis .Crotch. Therefore, at present, the known distribution of C. undecimpunctata L. in North America is al.ong the Atlantic coast from Massachusetts to Newfoundland and the distribution of C. difficilis Cr. is from Colorado, Utah and Nevada north to a point 60-75 miles north of Rampart House, Alaska.
