THE CANADIAN ENTOMOLOGIST. 177 



Primaries with 7 to lo on a stalk, 10 branching a very short distance 

 from the end of the subcostal, 7 to 9 branching rather beyond the middle, 

 of the common vein ; 3, 4 and 5 almost equidistant from the end of the 

 median. 



Secondaries with 6 and 7 forking from the subcostal shghtly before 

 the end of the cell ; 3, 4 and 5 very close together from the end of the 

 median. 



The antenna are simple in both sexes, and the tarsal claws are also 

 simple.

Habitat — California, Mexico. 

 Whether we have here to do with one or two species is a question ? 

 Packard, in describing his species, does not refer to aulcea at all. 

 Moeschler says the difference between the two is that m picta the costal 

 margin of primaries beneath is yellow, whereas in aulcea it is red. 

 Whether or not the Mexican form is different from the Californian ex- 

 amples must be settled by those who have the material. All the California 

 specimens I have ever seen refer to the picta variety.
