These specimens, though sHghtly smaller, agree very well with 

 individuals from Jalapa and Teocelo, Vera Cruz. 



Gryllus barretti Rehn.

 [Cuernavaca, Morelos.] 



Tuxpan, Jalisco. September 4, 1903. (McClendon.) One female. 



This individual fully agrees with the type of barretti, and is interesting 

 as it demonstrates the fact that the species is brachj'pterous as well as 

 macropterous, the typical series being in the latter condition. 



Gryllus mexicanus Sausaure.

 Brit. Mus., p. 94. [Mexico.] 



Guadalajara, Jalisco. September 14, 1903. (McClendon.) One 

 female. 



This specimen does not fully agree with Saussure's figures and descrip- 

 tion in the Biologia Centrali- America" as the pronotum is not so elon- 

 gate, though this may be due to sex, as Saussure figured a male and 

 the individual in hand is the other sex. Walker's description is so 

 general that little can be made of it, but the Guadalajara specimen 

 fully agrees with it as well as the structure of the opposite sex and the 

 insufficiency of the diagnosis will allow. This species has been 

 recorded from as far north as Tepic.
