Book excerpt: Excerpt from Some Miscellaneous Results of the Work of the Division of Entomology, Vol. 7 Report for 1856) a Very interesting article on the grain Aphis (aplw's avenge Fab), in which he made the unfortunate mistake of confound ing several other species with the true grain louse; erroneous figures of one of which were published on Pl. 1, figs. 5 and 6, representing a species of Siphonophora Arooiz. This error of judgment in distinguish ing genera as found upon grain has mainly been the cause to divert the attention of later entomologists from the true characters of the Species described by Fabricius. Until the spring of 1880 the writer also entertained the opinion that the species treated of by Prof. Cyrus Thomas, in his Eighth Report (pp. 51 was identical with that mentioned and described by Fitch as Apfiz's avenge Fab. During the spring of 1880, however, the writer became suspicious that something was wrong, since the description given by Thomas did not agree with that published by Fabricius. At that time I happened to examine a lot of aphides from Pocomoke City, Md, which were reported to be extremely numerous and destructive to wheat in that vicinity. These, in my opinion, agreed exactly with the description of ap/lz's arenze Fab., and Kaltenbach, but not with the description by Thomas, and I have held to this opinion ever since. The same form, having been found by myself or received from various localities, infesting grains or grasses, agrees well with the description of the Species published by Fitch, but not with that of Thomas.
