When seven years ago I had the honour of occupying the Presidential chair of this Society, I ventrued in my annual address, as some of you will doubtless remeber, to suggest the formation of a North American Entomolgists' Union on similar lines to those on which the American Ornithologists' Union has been so successfully carried on; and in my second address the following year I again returned to the subject.

In the following descriptions the term sericeous or sericeously roughened in applied to the silky lustre induced by the minute striation or roughening of the surface.

57. Tychea, Koch 1857, Pflanzelause, 296 t. graminis, Koch.*

58. Smynthurodes, Westwood, 1849, Gardener's Chron. 420, t. beta, Westw.

A fine large Oncideres, which agrees very well with the description of Thomson's tesselatus, was sent me lately for identification by Prof. Snow, who collected this fine addition to our fauna in S. Arizona this year. This occurence of this species in our fauna gives me the opportunity to make known another large Oncideres from Texas, apparantly new, which belongs with tesselatus to the sub-genus LochmŒcles.

The above-named paper which has lately appeared in the Deutsche Entomol. Zeitschrift (1905, II, pp. 1–56), is of the highest value of American students of the Coleoptera, though in these days of minute subdivision and endless creation of genera and species upon the lightest pretext, it come as a surprise to those who have consluted only our American publications on the subject.

Prof. Smith of New Jersey, records TŒniorhynchus (Culex) squamiger, Coq., as being a strictly fresh-water form in the State, and it will be interesting to know that so far as my experience goes during the past season, it is exclusively a salt-marsh mosquito in the San Francisco Bay region of Californa.
