Triosa marginata Crawford. 



The head and female cauda of this species come- exceedingly 

 close to T. maura. The length of branches of M and Cu are 

 different and a smoky caudal margin of the wing further char- 

 acterizes this species. The wing specimen at hand is 2.85 mm 

 long. Figs. 321, 332, and 360. 



Lot 1348 Sub 75. Two females with data "Ariz. 2217. 5-20-96. Tus- 

 con, Ariz. R. E. Kinze."

Trioza maura Foerster? 



Twelve collections are either maura Foerster as figured by 

 Sulc 191 1 or remarkably close to that species. Included here 

 are pale specimens with white faces and cones which are easily- 

 separated from black coned specimens in the collection by color 

 characters, but as they show no specific structural differences 

 I am of the opinion that the paler individuals are teneral and 

 that the darker ones are those with a more mature coloring. 



Wing measures about 2.85 mrh in length. Figs. 322, 323, 337, 

 349, 351, 359. Fig. 322 is a wing taken from a specimen with 

 black cones and Fig. 323 from one with white cones.
