308 THE ENTOMOLOGIST. 



ever, that while Dr. Keverdin has unravelled the tangled alveus 

 skein by the same entirely scientific methods, M. Charles Ober- 

 thiir, from personal field-knowledge of the so-called "varieties" 

 of alveus and serratuhe, and a close study of the series in his 

 museum, has arrived at almost similar conclusions, with the 

 addition of a new species, which, from its association with 

 western France, he names Hesperia armoricanus. Both authors 

 refer Conyzce to onopordi; cirsii, Kbr., retained as a separate 

 species by M. Oberthiir, is found by Dr. Keverdin to belong to 

 carlincB, Rbr., the whole group working out as follows: — 

 Hesperia alveus, Hb. (mountain form and type). 

 [a) var. (lowland form). 



{h) var. speijeri, Stgr. (Advanced to the rank of a 

 species in Staudinger's 1901 Catalogue on extremely 

 slender evidence.) 

 H. CARLIN.E, Rbr. 



(a) var. cirsii, Rbr. 

 {b) var. iherica, Gr. Gr. 

 H. ONOPORDI, Rbr. 



(fl) ? var. conyzce, Guenee. 

 H. FRiTiLLUM, Rbr. (? =fritilliim, Hb.). 

 H. sERRATULiE, Rbr. 



(rt) var. occidentalis, Lucas.* 

 H. armoricanus is described by M. Oberthiir as " more 

 nearly approaching carlince than cirsii," and, pending further 

 investigation, should therefore follow carlince in the above list. 

 So far it is reported only from Bretagne and the western littoral 

 Departments — as far south as Charente-Inferieure. 



Local races of H. alveus M. Oberthiir also describes and 

 figures as follows : — 



(c) var. constans, bellieri (Larche, Basses-Alpes, and Pyre- 



nees-Orientales). 

 {d) var. ? ab. numida (Lambese, Algeria), 

 (e) var. ? ab. foulquieri (Basses-Alpes and Bouches-du- 



Rhone). 

 (/) var. hallotce, Bsdv., in litt. (Dovrefjeld, Norway). 

 It remains only for entomologists on the spot to breed out the 

 several species and these local forms, in order to put their 

 identity upon an entirely satisfactory and final basis. 



Meanwhile, in presenting the summarized results of these 

 two important contributions to our knowledge of the Hesperiid 

 group, I have refrained purposely from entering into details. 

 In the case of the appendages. Dr. Reverdin leaves no shadow 

 of doubt in our mind as to the scientific value and accuracy of 



■■'• Described by M. Daniel Lucas, 'Bull. Ent. Soc. France,' 1910, as a 

 new variety of serratulce from examples taken by himself in the Forest of 

 Vouvant, Vendee. "Almost var. major, Stgr." — Oberthiir.
