stein). The altitude of the type locality, according to the data of the map, is about 900-1000 m; the foodplant and the collecting method are unknown. The distance of the two type localities is approximately 120 km, but they lie on the opposite sides of the main chain of the Pyrenees with 2500-3000 m altitude in average. These higher zones are far above the timberline, with pioneer rocky grasslands and nude stony walls and ravines. Thus the twin species have been evolved most probably from a common ancestor, as a consequense of the isolation of the formerly common area and the subsequent allopatric speciation. As the known material of the two species is very scarce, we have no information about the possible existence of populations with transitional morphological features. On the other hand, the type series of C. (T.) pinivorus is rather homogeneous, displaying only a small range of variation in the mentionable features. Etymology - The specific name refers to the indepted foodplant of the taxon. Acknowledgement -The author is greatly indebted to Dr Thiéry Bourgoin (MNHN, Paris) for his kind help with the loan of the holotype of C. lineolatus and the discussion supporting my opinion about the taxonomic relationships of the two species mentioned in the paper.
