(Ecanthus fasciatus. Fitch, 3d Report, Noxious Ins. 

 N. Y. ; 132 (omitting reference). (1856.) 



Not only do individuals of this species differ from one 

 another, as Fitch mentions in his distinctions between (E. 

 niveus and (E. fasciatus, but even to a much greater extent, 

 some males having three branches of the " fiddle-bow," 

 and some even five, while they take their origin and ter- 

 mination at very different points in different individuals, 

 and vary besides very much in coloration, many individ- 

 uals being met with of quite a dark color, especially upon 

 the abdomen and legs. These all belong, however, to one 

 species, no differences being discoverable upon which true 

 natural groups can be founded ; nor are there any such 

 concomitant characters among them as Fitch asserts ; 

 neither did Harris make any such blunder as to have mis- 

 understood the sexes in this^ genus as is alleged by him. 

 It would be strange indeed if an entomologist were not 

 acquainted with the very apparent differences existing 

 between them in the prolonged ovipositor of the female, 

 and peculiar structure of the wing-covers in the male.

I have never met with Gryllus bipunctatus, De Geer, 

 which Fitch refers to under the name of (E. punctulatus. 

 (3d Rep. 133). 



LOCUSTARI^3, Latreille. 



In a paper OH the genus Raphidophora, (Proc. Bost. 

 Soc. Nat. Hist. ; VIII. 6,) I enumerated the known species 

 inhabiting the United States, amounting in all to three, 

 and added to them descriptions of four others. Since 

 then I have had an opportunity of examining many other 

 species from various parts of the country, through the 

 kindness of Mr. Uhler, arid have made a study of others 

 in the Museum of Comparative Zoology, so that the num- 

 ber of species is found to be very considerable, and to
