In the article, ``Biology of Cybocephalus sp. nr. nipponicus (Coleoptera: Cybocephalidae), a Natural Enemy of Euonymus Scale (Homoptera: Diaspididae),'' by Juan Manuel Alvarez and Roy Van Driesche, published in Environmental Entomology, 27 (1): 130-136, the following correction is to be noted:

On page 132, 1st column, the equation should read as follows:

Arcsine (Square root %) = [gb]0 + [gb]1A + [gb]2D + [gb]3A2 + [gb]4D2 + [gb]5A*D.
