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,
