THECLA SYLVINUS AND ALLIED SPECIES. 



By William Phillips Comstock, Newark, N. J. 



1. Thecla sylvinus, Bdvl., 1852. Region of San Francisco, Cal. 



Var. itys, Edw., 1882. Prescott, Arizona. 

 Var. putnami, Hy. Edw., 1876. Utah. 



2. T. dryope, Edw., 1870. California. 



3. T. acadica, Edw., 1862. Eastern States. 



Syn. souhegan, Whitney, 1868. 



4. T. californica, Edw., 1862. California. 



Syn. horus, Bdvl., 1869. California. 

 Syn. cygnus, Edw., 1871. Nevada. 



The recent appearance of M. Oberthiir's paper figuring the 

 Boisduval types furnishes an opportunity for the revision of that 

 group of Theclas about which considerable ignorance has existed 

 since the days of W. H. Edwards and Henry Edwards who de- 

 scribed the majority of the species. 



T. sylvinus, the first species of the group to be described, has 

 never until now been figured, and has not been recognized by 

 American entomologists, a fact that W. H. Edwards remarked 

 upon in his Catalogue of Diurnal Lepidoptera of 1884. I have 

 specimens fromf Pasadena, Cal., Summit, Cal., and one male cap- 

 tured by Henry Edwards, labeled Sierra Nevada, Cal., which are 

 quite typical ; also a series from Jemez Springs, New Mexico, and 

 Verdi, Nevada, which are slightly more ruddy above than the type. 



I have listed T. itys as a variety of sylvinus. It was described 

 from one male and two females from Prescott, Ariz., and there 

 were apparently more specimens before the author when he made 

 his description. I have a male metatype bearing W. H. Edwards' 

 label which is curiously marked a female. Dr. Holland in his 

 " Butterfly Book " figures a male which he also calls a female.
