and second only showing feeble punctuation, and with the disk of the elytra 

 destitute of the setigerous punctures that occur on the fourth and seventh 

 intervals in canadensis. In canadenis the fourth interval bears six to eleven 

 setje, the seventh interval five to eight setae ; in blanchardi no setse or 

 setigerous punctures are found on these intervals. The submarginal interval 

 also usually bears fewer setse in blanchardi (about 12) than in canadensis 

 (about 16). Length, 11 to 13 mm. 



Occurs in White Mountains of New Hampshire and near the sum- 

 mit of Mt. Watatic in Massachusetts, very near the New Hampshire 

 Line. Type from Randolph N. H., in my collection ; other specimens 

 in Mr. Blanchard's collection. 



In regard to the subgenus Psctidonomarctus, it may also be added 

 that the tendency toward a loss of the elytral striae is carried further 

 in a specimen in Mr, Blanchard's collection from North Carolina 

 (Highlands) than in any of the described species in that only one 

 sutural stria remains. It probably represents a new species, though 

 additional specimens might show intergrading forms. The rarity 

 in collections of most of the species of Nomaretus inhabiting the Alle- 

 gheny Mts. makes their study difficult especially in determining the 

 limits of individual variation. 



NOTES ON CICADAS FROM THE UNITED STATES 



WITH DESCRIPTIONS OF SEVERAL 



NEW SPECIES. 



By Wm. T. Davis,

While the writer has a rather large collection of Cicadas from 

 the United States, more material may cause the opinions here ex- 

 pressed to be considerably modified. Especially is this the case re- 

 garding those species originally described without locality, such as 

 sii'alei, olympnsa, viridifascia and scx-guttata. More specimens are 

 also to be desired from the type locality of what is here considered 

 as Say's Cicada vitripennis^
