THE LINN^EAN GENUS GRYLLUS— ADDITIONS AND COR- 

 RECTIONS. 



Quite recently I was kindly informed by Mr. S. H. Scudder, that in 

 my paper on the divisions and species of the original genus Gryllus 

 (Canad. Ent., XXXIII., pp. 118-121), I had overlooked the fact that 

 Fieber's paper had appeared in Lotos in 1853. With the information 

 furnished by Mr. Scudder, I examined the work, and found that Meco- 

 stethus appeared in the May number, on page 99, and PacJiytyhis and 

 Psoplius in the June number, on pages 121 and 122, respectively. This 

 fact further clinches the Linnrean Locusta on Fischer's Stenobothrus. 



The date given for Thunberg's Gomphocerus is erroneous, and should 

 be 1815, while the original spelling of Bolivar's " Humbella" is Humbe.
