pale yellowish, probably pruinose in fresh specimens, with a narrow 

 black portion in the center and the pleura also are sometimes black. 

 The opercula are about as broad as long, rather convex and uniformly 

 pale yellowish in color. The uncus of the genitalia is stout and dilated 

 subapically. 



Types : $ and 9 , in the collection of the New Jersey 

 Experiment Station; co-types in U. S. N. M., and Acad. Nat. 

 Sci., Philadelphia. 



Described from five males and three females; Anglesea, 

 N. J., August 25th; Paterson, N. J., September 4th; Miami, 

 Florida, August 13th, Georgiana, Florida. 



This is a very distinct species hitherto confused with cani- 

 cularis. It may be separated at once from that species by the 

 greater width of that portion of the pronotum posterior to 

 the transverse sulcus, by the shape of the black marks on the 

 anterior portion of the pronotum and by the comparatively 

 narrow black central portion on the under side of the abdomen. 



Cicada marginata Say. 



This, the remaining species of Cicada — using the term 

 within generic limits — in New Jersey, is so distinct from any- 

 thing else that a detailed description of it at this time is 

 unnecessary. It may be recognized by its large size, averaging 

 over 40 mm. to tip of abdomen, and over 60 mm. to tip of 

 wings, and its exceedingly robust form. The thoracic mark- 

 ings illustrate the general type of maculation, and the body 

 above as well as below is largely pruinose. The opercula of 

 the male are broader than long, pale green covered with white, 

 pruinose and the anal abdominal segment below is considerably 

 broader than long. The male genitalia are chunky, with the 

 uncus knobbed at the apex. 



It occurs commonly in the southern portions of New Jersey, 

 more rarely northernwardly, and is recorded from New York 

 to the Gulf States and as far west as Utah. 



Plate III, figures 7 and 8, illustrate the genitalia of a Mexi- 

 can species of Cicada, which we have not attempted to identify 

 and present merely to show the variation of the structure in the 

 genus. The specimens were sent from the U. S. N. M., with 

 the tibicen, and were labelled C. opercularis Oliv., which, of
