Victoria, Tamaulipas, January 14 or 15, 1903. (S. N. Rhoads.) 

 Two males, two females. 



One of the male specimens was kindly compared by Mr. A. N. Cau- 

 dell with typical specimens from San Luis Potosi, and he states that 

 they are probably identical, though some slight differences do exist. 

 The drawing of the genitalia given by Scudder is misleading, as one 

 receives the impression that the subgenital plate is longer in the Vic- 

 toria males, while Mr. Caudell, after comparison with a co-type, states 

 that the reverse is true.
