friends, accumulated a collection of about one hundred specimens of 

 this species from Wells County, Indiana (E. B. Williamson), 

 HolHster, Missouri (H. H. Knight), Falls City, Nebraska (H. G. 

 Barber), Wakefield, Kansas (J. C. Warren), McPherson, Kansas 

 (Warren Knaus), and Chetopa, Kansas (D. R. Beardslee). We 

 have also examined many more in other collections including several 

 from Texas. From this evidence it appears that the coast speci- 

 mens, which have the stripe on the third abdominal segment com- 

 paratively broad, constitute a variety and cannot be considered typical 

 with those from the interior of the country which have the stripe 

 more attenuated or sometimes wanting. Of the variety we have 

 collected about twenty in Cape May County, New Jersey ; Mr. Francis 

 Harper has sent us seventeen from the neighborhood of Beaufort, 

 N. C, and a number of others have been examined in collections, 

 from along the coast of New Jersey, and North Carolina, and two 

 examples marked " Pennsylvania " are in the collection of the 

 Academy of Natural Sciences of Philadelphia. In the collection of 

 Mr. Otto Hiedemann there is a male of this variety from Victoria a 

 town near the coast of Texas, and in the Uhler collection, U. S. Nat. 

 ]\Iuseum, there is a specimen collected by Belfrage in Texas. 



Say says of Cicada pruinosa: "Found on the Missouri; it is also 

 very common in Pennsylvania, and much resembles C. tibicen Fabr., 

 but differs in being pruinose beneath, and in having white abdominal 

 spots." Probably true pniinosa as well as the variety occurs in Penn- 

 sylvania, the latter being confined to the coastal region. 



Cicada pruinosa was originally described in part as having the 

 " tergum black : segments destitute of differently colored posterior 

 margins, basal segment with a white pruinose spot each side of the 

 back, another transversely elongated and attenuated one on the lateral 

 base of the third segment, and another upon the lateral base of the 

 caudal segment : venter dusky in the middle : caudal segments beneath 

 testaceous, dusky near the middle tip." 



Smith and Grossbeck say of the specimens they had from the 

 coast of New Jersey and which we now know to be a variety : 

 " Abdomen above black, base of first segment with a white, heavily 

 pruinose lateral dash, which encroaches to some extent upon the 

 second segment; a similar but longer and broader lateral dash extends 

 along the base of the third segment and a spot of the same color is
