ELACHISTIDAE 



COELOPOETA BALDELLA, n. sp. 



Palpi, head and thorax white. Antennae white witli black annulations. 

 Forewings white more or less suffused with golden ochreous and in some speci- 

 mens dark brown, scattered scales, mostly on the outer half of the wing. Some 

 specimens are nearly unmottlcd white except for a small suffused area below the 

 end of the cell on which the darker scales persist. Cilia white sprinkled with 

 ochreous. Hindwings and cilia white on the upper surface. Underside of both 

 wings dark fuscous, contrasting strongly with the white upper surface of the 

 male. Legs white sprinkled with dark fuscous. Abdomen silvery white. 



Alar expanse, 10-14 mm. 



Habitat: Camp Baldy, Bernardino Co., California. 



Type and cotypes in Collection Barnes; cotvpes in U. S. National Museum 

 (No. 22676). 



A very large series, more than one hundred specimens, shows this 

 species to be very close to the type of the genus Coelopocta gliitinosi 

 Walsingham, but much lighter in color than the large series of cotypes 

 sent to the National Museum by Lord Walsingham. The description 

 of C. glntinosi however would include the present species and it is pos- 

 sible that Lord Walsingham had a mixed series before him. Exam- 

 ination of the genitalia prove these to be of a simple primitive type 

 without much specific differentiation but sufficient to indicate that the 

 two species are distinct and not merely varieties. 



The genus Coelopoeta is intermediate between Elacliista Auct 

 and Cygnodia Herrick-Schaefifer, correlated with or derived from the 

 latter.
