By far the most complete description of 5. titus is to be found 

 in "The Butterflies of the Eastern United States" by S. H. Scud- 

 der. However, he makes no reference to such a variation as I 

 have described, but calls attention to the fact that "male speci- 

 mens from Idaho and Minnesota differ from all others that I have 

 seen in having the spots of the inner row of both wings much 

 larger, being nearly half as large as the marginal spots of the hind 

 wings. " 



Mr. Scudder also gives us infonnation concerning the distri- 

 bution, and his faunal map shows the species extending from 

 northern New England to central Georgia on the Atlantic coast, 

 and then in a broad belt westward along the line of the Lakes 

 on the north and through central Texas to Arizona on the south. 

 It also extends westward to the coast through the states of Mon- 

 tana and Washington. Mr. Scudder's map excludes southern 

 Texas and the larger part of Utah from which I have specimens, 

 and shows but one Canadian locality, in the Province of Ontario, 

 though specimens are now recorded from Manitoba. 



So far as I know 5. titus is not recorded from California, but 

 the type locality of the synom^an mopsus is given as Georgia 

 and Florida, although I know of no actual Florida records. 



I record one other specimen, a male from Texas, which is 

 interesting because the marginal row of spots on the secondaries 

 beneath are pale buff and the specimen is of large size, being 

 about 37 mm. in expanse. Otherwise it is typical. More material 

 might prove this to be a member of a local race, presumably a 

 desert form.
