Hub. Claremont, Calif. {Baker ; Pomona coll., 228). 



This extraordinary species might have been referred to a 

 new genus, but it is evidently related to P. atriceps (('ress.), 

 from which it ditl'ers by the large head with toothed 

 cheeks. 



Perditn feilorensis, sp. n. 



? . — Length nearly 5 mm. 



Like P. vespertilio, Ckll., except that the flagellum is 

 longer and darker, and conspicuously hooked at end ; and 

 the clypeus is dark brown with a white cuneiform mark on 

 each side. The lateral face-marks are between triangular 

 and quadrate, notched above ; tubercles with a small white 

 spot. Wings clear, with hyaline nervures and stigma. 

 Abdomen dark brown, without markings. Legs dark brown, 

 the tarsi pallid. The apical two-thirds of the Hagellum is 

 rather narrowly testaceous beneath. 



Hub. Fedor,' Texas, April 29, 1898 (Birkmann, 87). 



Very close to P. vespertilio, but apparently distinct. 

 Mr. Birkmann has also taken P. ignota, Ckll. (Lee Co., 

 Texas, Oct.), and P. crawfurdi, Ckll. (male, Fedor, May 7).
