as before, and again gives America meridionale as the habitat. 

 To this is added, in the Academy copy, in Say's handwriting, 

 "St. Paulo, Brasilia, Germar," indicating that some effort has 

 been made to identify this with a South American form. 



At p. 37, variegata is again described, placed as before and 

 recorded from Carolina. 



In 1825, Say described his pruinosa, knowing of the Fabri- 

 cian and Linnaean species ; but what forms he identified with 

 the names I have no means of knowing. 



In 1830, Germar gives in Thon's Archiv., II, p. 40 et seq., 

 a descriptive list of Cicadids in which he refers to -variegata 

 Fabr., describes it at some length, and cites Roesel's Ins., pi. 

 XXV, f. 5, as representative of the species. 



Roesel's figure, unfortunately, tells nothing. It is not well 

 drawn for identification and may be meant for any one of 

 half a dozen or more species. It is said to be an "Indian" 

 variety, but this may mean American as used. 



Germar also refers to operations Oliv., gives Java as the 

 habitat, and then adds that he believes it to be a variety of 

 variegata in spite of the difference in locality. He cites Stoll's 

 figure as usual and there is at least one important hint in 

 this, because Stoll's figure does resemble scptcndccitn in gen- 

 eral build, and the Fabrician comparative reference is there- 

 fore in so far confirmed. 



Walker's work in 1857 adds little to our knowledge, but he 

 makes lyricen De G., pruinosa Say and mannifera Linn, syno- 

 nyms of tibicen, while recording operations as a species un- 

 known to him. 



In 1869, Stal in his Hemiptera Fabriciana, II, 6, cites the 

 tibicen of Linne, gives all the Fabrician references, adds as an 

 additional synonym operations Oliv., gives America meridion- 

 alis as habitat and then comments : — this species inhabits boreal 

 America. 



Since that time matters have remained much as Stal left 

 them. In 184 1, Dr. Harris described canicularis in "Insects 

 Injurious to Vegetation," p. 175, but Fitch disposes of that 

 species in his Third Report in 1856. He says pruinosa is tibicen 

 with the mealy powder not rubbed off, and canicularis is only a
