 pronotum beyond post, fern., S 2-2-5, $ 2-5-3-5 ; wings beyond pronotum, S 1-2, 2 1-5-3 millim. 



Hob. Mexico, Coliraa (coll. S. H. Scudder: $ ), Chilpancingo, Rincon, and Xucu- 

 manatlan, all in Guerrero, 2800 to 7000 feet (H. H. Smith : 6 2 ), Jalapa (coll. Bruner 2 ) ; 

 Guatemala 1 , near the city (Champion: <j $ ) ; Nicaeagua, Chontales (Janson: s), 

 Ometepe (ShimeJc, in coll. Bruner 2 : <S 9 ). 



This is an easily recognizable species, though very variable in size, as the above- 

 given measurements show.

Hab. Noeth Ameeica, South-western United States, Lower California.— Mexico l 2 , 

 Cuernavaca (Beans, in coll. Bruner) ; Nicaeagua, Ometepe (ShimeJc, in coll. Bruner 4 ). 



This species is common in the South-western United States of America, having 

 been recorded from California, Colorado, Arizona, and Texas, and is probably more 

 plentiful in Mexico than the material at hand seems to indicate. I have also seen 

 specimens from San Jose del Cabo, Lower California, Cuernavaca, and Ometepe. 

 The long-winged form is distinguished as P. toltecus extensus ; it has been found in 

 California 4 , as well as at Ometepe, Nicaragua 4 .
