August — October 1S90. PSYCHE. 3.S7 edge Is blackish on the Sth and 9th segments, the vulvar lamina with the lobes more pointed on the tip, and better separated at the base. If D. Jlavicosta^ as I believe, is merely a variety of D. madida^ four smaller females from Victoria, Vancouver Island, July, can not be separated. The smallest is 31 mm. in length; alar expanse 50mm. ; pterostig-ma 2 mm. The wings are fumose, the anterior margin flavescent in one, another has the l)ase to the nodus or only beyond the triangle flavescent ; the anterior pale band on the sides of the thorax is plainly visible ; a large black band on each side of the abdomen is complete ; in one female the black extends from the end of the segments to the middle ridee. SYNONYMY OF THE HOMOPTERA DESCRIBED BY SAY, HARRIS AxND FITCH. BY E. P. VAN DUZEE, BUFFALO, N. V In the /lomoptcra as in other branches of our favorite science a solid founda-tion was laid by that illustrious pio.neer of American entomology, Thomas Say, whose brief but concise descriptions of manv of our native insects have eli-cited universal commendation from later students. Scarcely inferior to that of Say is the work done many years later by Asa Fitch most of whose numerous species mav be readily recognized from his short, clear diagnoses. Intermediate in point of time comes the work of Thaddeus William Harris to whom, however, we owe the description of but very few homopterous insects. In the present paper I propose to give the cor-rected nomenclature of the homoptera cicadinae described by these honoied leaders of American entomology so far as it is known to myself or has been made known l)v recent writers. Many of these names have been in common use for years, but a number are to be found only in rare or little known papers, and not a few are now for the first time systematically placed. In a few cases where I still feel in doubt the reference is followed by a question point. Of the 71 species described by Say 60 are known to me ; all of tliose de-scribed by Harris, 6 in nimiber, and all but 15 of the 74 species described by Fitcli. Two of those described by Say, viz., y ass us sanctus ant! Membracis SHbulatUy are, so far as I can learn, un-known to our later entomologists. In the cicadidac and typhlocybidae I have quoted all references from the studies of Messrs. Uhler and VVoodworth whose valuable synonymical notes on these families may be found in Ent. Amer. v. 4, 21 and Si, and Psyche,
