Though some amount of variation is shown in each of the series 

 before us, there appears to be little difference in the size and pro- 

 portions of specimens from the various natural divisions of the range 

 of the present insect. As has been noticed in other species, macrop- 

 terous specimens always are found to have the pronotum more 

 widened caudad. 



Color Notes. — The great majority of specimens from Texas are of 



°' This specimen is the type of A^. comanchus Saussure.
