GENUS DIRCENNA DOUBLEDAY 



Medium-sized butterflies, with quite transparent wings. 

 Abdomen not as long as in the preceding genus. Hind wing of 

 male strongly bowed forward at middle, the costal vein tend- 

 ing to coalesce with the subcostal. Only one species occurs 

 in our region. There are many species in the American tropics. 



(1) Dircenna klugi (Hiibner), Plate III, Fig. 1, d" (Klug's 

 Dircenna). 



The wings are pale brown, narrowly margined with darker 

 brown; the fore wings have a pale yellowish diagonal bar at 

 the end of the cell, followed by two bands of similar spots, 

 curving from the costa to the inner margin. Expanse 2.5 to 

 2 75 inches. 



Habitat: Southern California and Mexico according to Rea- 

 kirt. The citation of California by this authority may refer 

 to Lower California. In recent years no specimens have been 

 taken in Upper California. It may be that with the changes 

 which have taken place in the development of the country the 

 insect has become extinct about Los Angeles and San Diego, 

 where Reakirt collected.
