ON SOME RACES OF LASIOCAMPA QUERCtS. 313 



volcanoes were practically devoid of insect life altogether. A few Krehia 

 aet/nops flitted among the bracken, and one or two Lcptidia sinapis, 

 and with them ended my collecting abroad for 1901. From a purely 

 entomological point of view the expedition was not an unqualified 

 success, though in every other respect delightful. The Cevennes, 

 poor in forest trees and flowers, show a corresponding scarcity of 

 lepidoptera. All the species encountered — with but few exceptions — 

 were small and stunted, and quite unlike the splendid forms of 

 similar Pala^arctic insects occurring in the Basses-Alpes and the 

 mountains of central Europe. The roadside banks and cuttings, 

 prolific of life elsewhere, yielded nothing but a few Satyrids, of which 

 the iS'. statilinus struck me as peculiarly meagre-looking insects. On 

 the other hand S. circc, as I have already stated, was present in 

 great profusion, and fully up to the normal size. Subjoined is a com- 

 plete list of the Rhopalocera observed between July 16th and August 5th, 

 inclusive, at Florae, in the gorges of the Tarn, at Mende, Balsieges 

 and Clermont Ferrand, numbering in all seventy-four species :

The Cross-breeds. — For convenience of reference the various races 

 on which we worked received numbers as follows : — 



(1 and 2) L. var. meridionalis, Tutt. (3 and 4) L. var. rihurni, 

 Gn. (5) Dorset L. qnercns. (6) L. var. mrridionalisx vibnrni, with 

 white-haired larvie. (7) L. var. meridionalis xviburni, with brown- 

 haired larvae. (8) L. var. ealhniae from Aberdeen pupie. (9) L. var. 

 siciila, Stgr., of Sicilian parentage. (10) Paris L. qnercfis. 



The following 28 crosses were obtained, or attempted (the <? being 

 first mentioned in each case) : — 2x3 ( = 6 and 7), 2x4, 2x8, 3x5, 

 3x8, 5x2, 6x2, 6x3, 6x5, 6x6, 6x8 (did not lay), 7 X 2, 7 X 3,
