Professor Ball, however, finds but one generation in Colorado. He writes us as follows: The species (0. lutcralix) is but single brooded in all parts of Colorado from the coldest to the warmest. The adults hil^ernate over winter, as do all of the tettigonids here, and are common from the middle of March into June, most of them disappearing by the middle of that month; but a few scattering ones run on into July. They lay eggs in May and June. The first larv;e apjiear about May 24 and continue to cnne out through June, the last ones disappearing in August, about the 15th. Fresh males appeared July 6âthe females not until laterâand ran on tiirough the season, without mating or developing eggs. Thus there is a wide variation in the time of appearance of all stages; one could find nearly full grown larva' in June and again in August, two months later". From almost daily ol)servationH on a single area where they were common, I am very positive that there is but one brood. The difference in latitude l)etween Colorado and Texasâequal to that between Washington, I).

Front longer and narrower, proportionately, giving the larva a much more pointed head as viewed from the side, and a long sloping face. Color
