Notes on the Genus Hemiargus Hiibner in Dyar's 



List (Lep.). 



By G. T. BETHUNE-BAKER. Edgbaston, Birmingham, England. 



Months ago my friend, Dr. McDunnough, wrote to me in 

 reference to the confused state of Lycaena hanno Stoll. and 

 asked if I would attempt to clear up the synonymy of it and 

 its near allies. The only way to do this was to see Boisduval's 

 types and also to endeavor to settle whether antibnbastits 

 Hb. was the same species as hanno. The oft-experienced and 

 renewed kindness of Monsieur Charles Oberthiir has relieved 

 me of the first difficulty, for he has been so good as to send 

 me all the necessary specimens from the Boisduval section of 

 his magnificent collection, so that, with these before me, the 

 second point will be easier. 



In Dyar's list we find all these species grouped as follows 

 under the genus Hemiargus: 



Hemiargus Hiibner. 



444 isola Reakirt, Proc. Acad. Nat. Sci. Phil. 3321866. 



Syn. zachaeina Butler & Druce alee Edwards.

 & Le Conte, astcnidia Boisduval (recte astcnidas), filcnus Poey.

Taking these into consideration seriatim, we have first to 

 settle the genus Hcmiargns Hiibner. 



Scudder (Hist. Sketch p. 186) names bitbastus, parsinwn 

 (celaens), lyshiion (ubaldiis}, Jianno, isis (isarchus) , larydas, 

 and he says hanno may be selected as the type. In making this 

 selection he gives Hiibner's Yerz. Bek : Schm. p. 69, as his 

 only reference and he dates that work as 1816. We know, how- 

 ever, today that that date is 'an error; pages 65-80, with spp. 

 622-819, cannot have appeared earlier than 1822 ( Durrant and 

 Sherborn both agree on this point). This is proved by the 

 fact that these pages of the J'crzcichiiiss have several refer- 

 ences to his ( I Kilmer's) earlier work, the Zulriujc, in them.
