HAAS: ABIDA AND CHONDRENTA. 285 



extraordinarily large but otherwise typical bigorriensis, which 

 besides its size is distinguished only by the weak development 

 of its teeth and lamella?. My specimens vary between 11 and 

 12 mm. high and 4 to 4.5 mm. diameter. Further on we will 

 come to a pronounced giant form of C. bigorriensis tenui- 

 marginata (DesM.). 



What Pupa cereana Kstr. is will probably never be cer- 

 tainly known. According to Raster's illustration we have to 

 do with a species very closely related to bigorriensis, perhaps 

 quite identical with it; but the locality records, France and 

 southern Germany, does not permit this view. Westerlund 

 mentions Carinthia, southern France and northern Spain as 

 further localities, whereby the records of Kiister become some- 

 what easier to understand, since his "Siiddeutschland" may 

 very well coincide with Westerlund 's "Karnten," as in Kiis- 

 ter 's time Austria-Hungary was still considered a part of 

 Deutschland. But in Carinthia, C. megacheilos (Cr. & Jan) 

 occurs, which under the circumstances might be taken to be 

 Kiister 's cereana. The western distribution, southern France 

 and northern Spain, would answer therefore for C. bigor- 

 riensis, though the conjectures expressed above do not justify 

 placing cereana directly in the synonymy of that species. 



Pupa baregiensis Locard and P. centralis Fagot, both from 

 the High Pyrenees, are known to me only by the descriptions, 

 which indicate relationship with bigorriensis. Considering 

 the species-splitting of their authors, we will not go far wrong 

 if we conclude that their species were based upon individual 

 variations of C. bigorriensis bigorriensis. 



Bofill and Haas have mentioned this local race under the 

 name P. megacheilos bigorriensis, and have recorded it from 

 the Valle d'Aran, the part of Spain lying on the north side 

 of the Pyrenees, through which flows the uppermost Garonne. 



For the distributon of C. bigorriensis bigorriensis can be 

 given in general: the High Pyrenees. Moquin-Tandon men- 

 tions also C. b. tenuimarginata from there (at Luchon) ; but 

 I convinced myself, by examples from him in Rossmassler's 

 collection, that there had been an exchange of specimens. 

 We may therefore regard C. b. bigorriensis as the local race
