162 THE entomologist's record. 



zag leads to the Weisses Kreuz, and immediately beyond this there 

 occurs the only chance one has of missing the way, a path diverging to 

 the right, which leads to a cave but goes no further. At the Quelle, 

 which is the favourite haunt of several species of butterflies, the routes 

 diverge. The right hand path leads up to the Kleiner Domogled, 

 where one emerges from the forest, though one must not expect to 

 meet with many insects until one has traversed the intervening ridge 

 and reached the peak of the Domogled itself. The left hand path 

 leads to the summit of the Suskului and, although we made only one 

 ascent towards the end of our stay, we were on this occasion surprised 

 that it had not been more recommended by previous visitors ; it is only 

 described by Dr. Rosa, though the ascent is much more direct than 

 that of the Domogled, pleasanter, and on the whole more productive. 



The Hesperiidae seem to be comparatively scarce in this part of 

 the country, and were represented only by occasional specimens of 

 Krynnis alcaeae, E. althaeae, Hesperia cartliami, Nisoniades toijen, 

 Aufiiades sylvanus, and Adnpaea flava. The Coppers were represented 

 by three species — Heodes virganreae, Lmreia alcipliron, and lUimicia 

 phlaeas, which were to be found most abundantly in the meadows 

 at the head of the valley, but sometimes also at the Quelle. The 

 specimens of H. virifaurcae are considerably larger than any we have 

 taken in Switzerland or the Pyrenees (up to 46mm.''') and they shew 

 a marked tendency to obsolescence of the white markings on the 

 underside hindwing. The J s of H. alciphron are all darkly suffused 

 with purple, and the $ s are of the typical dark brown form with an 

 orange band on the hindwing. The <? s of B. phlaeas are considerably 

 suffused, and both sexes are very distinctly tailed ; they are, however, 

 not dark enough to be typical ab. eleus, and must perhaps be referred 

 to ab. siiffasa. 



The blues to be found at Herculesbad did not include many species, 

 but this was compensated for by the great abundance of Scoiitantides 

 orion : this species was also very variable, and, though the majority 

 are of the form var. ornata, our series contains several specimens of 

 var. nif/m and every intermediate gradation. S. orion occurred not 

 only in the valley, but also on the Domogled route up to the summit 

 of the peak. In the latter locality, at an elevation of over 6,300 feet, 

 we made one of our most interesting captures, and the only one which 

 was totally unexpected, namely, Aricia anteros. Of this species 

 we took five <? s on July 1st and 3rd, three of which were quite fresh. 

 They were found over an exceedingly restricted area on the top of 

 the Domogled, and we mistook them at first for P. eros; a comparison 

 shews, however, that the ground colour of A. anteros is rather greener 

 than that of P. eros, and the former is further distinguished by its 

 chequered fringes, by the more suffused dark borders of the forewings, 

 by a well marked discoidal spot on each wing, by the large orange- 

 ringed black spots bordering the hindwing upperside (though the 

 orange is almost absent in one of the specimens), and by the very 

 pronounced series of orange spots bordering the underside of both 

 wings. Kane also describes the possession of one, and sometimes 

 two, basal spots on the underside forewing as a distinctive difterence 

 from the underside of Aricia astrarche ; of our specimens, however, 



* This and subsequent measurements are obtained by doubling the distance 

 from the tip of the forewing to the centre of the thorax.
