\^ol. Xxii] EXTOMOLOGICAL XEWS. 415 



white fascia, edged narrowly by a black line, and interior to 

 this in the basal upper half wing, is a blue fascia narrowly 

 lined with black, and still nearer the base is an orange brown 

 fascia edged with black and the base of the wing is blue. In 

 calif ornica the first blue fascia is replaced in its lower half by 

 an orange brown spot and this spot is separated on its lower 

 half from the inner orange brown fascia by a blue space. 



These maculations of the upper half of the hind wing basally 

 are very marked and serve to sharply separate the two species. 

 If intergrades occur I have not seen them. 



Another character of moment is found in the border of the 

 under side of both wings. In hredoivi there are two rows of 

 submarginal lunules ; the outer ones narrow and the inner ones 

 three times the width of the outer ones. In californica the 

 outer row of lunules is absent or only faintly indicated. 



None of the markings of the upper side of the wings serve 

 to differentiate the two forms. 



The following are the records : Four specimens of califor- 

 nica (presumably from California) ; four specimens from Cali- 

 fornia (no exact data) ; one from the San Bernardino ^foun- 

 tains, Cal. ; one from Los Angeles, Cal. ; one from Tehachapi, 

 Cal.. July 6th; one from Havilah, Cal., June 17th; two from 

 Ashland, Oregon, Sept. 7th and 30th. 



Nine specimens of bredoici, Carr Canyon, Huachuca Moun- 

 tains, Arizona, Aug., taken by myself; one from the City of 

 Mexico and three taken by H. A. Wenzel in the Chisos Moun- 

 tains, in southern Texas, July 22nd. 



The Cotton Moth in Large Numbers. — From September 23rd to 

 the 26th, Philadelphia experienced a large flight of the cotton moth, 

 Aletia argillacea. They swarmed in some parts of the city and hun- 

 dreds were resting head down on the electric light poles and on plate 

 glass windows of stores. There were many thousands of them and 

 nearly all that I saw were in perfect condition as though just from 

 the chrysalis. These moths are known to migrate in numbers, but it 

 is quite strange if the great numbers seen here came from the cotton 

 districts in the south. The moths in some places appeared to create 

 considerable alarm, people thinking they would cause damage to plant 

 life here. — Henry Skinner, Philadelphia.
