COCKERELL ON PANURGUS AND CALLIOPSIS

Extract

Prof. cockerell's treatment of these genera is likely to create an erroneous impression, which should be corrected wherever his statements are made. In Trans. Am. Ent. Soc., XXIV., 150, he says : “It is perfectly evident that the so-called species of Panurgus of North America are not all of the same genus.” In the Dec. Can. Ent., p. 287, he says : “The result is extremely interesting, and seems to show that we have for many years been placing bees in genera to which they by no means belong.”
