This insect was first known in 1876, near Fremont, Nebraska, where it was taken and named. It then disappeared from that vicinity, its disappearance caused, it has been surmised, by the severe grasshopper invasions of 1875 and 1876, and was unknown until 1911 when it was reported as doing much injury to small grains in Alberta, Canada. During the succeeding years it appears to have moved south, or, possibly, to have multiplied locally, and in 1919 it was doing noticeable damage to crops in eastern Montana and western North Dakota. Its chief injury was to wheat and corn but it also attacked rye, barley, oats and, to a limited extent, flax and millet, also potatoes.

notice of printer's error. Description No. 15 in the December, 1927 issue should read—Lycaena helloides (Bdv.), tr. f. sternitzkyi, instead of Lycaena thoe (Guer.), tr. f. sternitzkyi. Author's manuscript, as submitted. stands correct and illustration No. 15 is obviously not a thoe (Guer.).

In working up considerable material which the writer collected in the western United States certain new species of Hadronema have been recognized, with the result that a key is provided for the thirteen known species of which five are described as new. In 1918, Mr. E. H. Gibson published a key (Can. Ent., xl, pp. 81-84) to the species known to him, describing two new species. The writer examined these types in the U. S. National Museum during 1926 and found that Hadronema confraterna Gib. is in fact a good species of Lopidea, allied to Lopidea lepidii Kngt., but smaller and the left clasper somewhat differently shaped.
