milled, C. morpheus, C. alsines, C. taraxaci, C. ambigua, Amphi- 

 pijra tragopogonis, A. pyramided, Calymnia trapezina, Cosmia 

 paleacea, Dyschorista suspecta, D. fissipuncta, Pyrrhia umbra, 

 Catocala nupta, Aventia flexula, Zanclognatha tarsipennalis, and 

 Z. emortualis. A fine specimen of Cerura furcula was found at 

 rest on a pine-trunk. Neuroma cespitis, N. popularis, Plusia 

 chrysitis, P. festucce, a,nd G. papilionaria came to light. Rhodo- 

 strophia vibicaria, Scotosia vetulata, Cidaria prunata, C. populata, 

 C. associata, C. dotata, C. truncata, Larentia fumata, L. didymata, 

 L. vittata, L. bilineata and L. comitata, Phibalapteryx polygram- 

 mata, Ellopia prosapiaria, Semiothisa liturata, Boarmia roboraria, 

 B. lichenaria, Gnophos obscuraria, Bupalus piniarius, Perconia 

 strigillaria, Acidalia bisetata, A. deversaria, A. emarginata, and 

 A. marginepunctata were netted while putting on the sugar. 



On July 27th a visit was paid, with a couple of friends, to the 

 limestone hills of Eiidersdorf. The day was delightful, and 

 butterflies were in profusion. Dryas paphia, Argynnis aglaia, 

 and A. niobe were in fine condition; Epinephele jurtina, C. 

 arcania, C. ijihis, and C. pamphilus were in countless numbers. 

 Chrysophanus virgaurece was in fine condition. The blues were 

 somewhat scarce, only two Lycana cyllarus, two L. arion, and 

 about a dozen L. argus being boxed . Up a stony path a fine 

 A. lathonia was netted as it was sunning itself on a stone, and 

 then I saw for the first time that fine butterfly, Satyrus alcyone, 

 sailing majestically through the air. It is fairly difficult to cap- 

 ture ; one must wait till it settles, and then approach carefully. 

 In about half an hour four fine specimens were netted. Its near 

 relative, S. semele, was also about. Both these species have the 

 habit of settling on pine-trunks, and are then quite invisible. 

 Later in the season we frequently found S. alcyone sitting on the 

 old sugar patches when putting on the sugar, and a good series 

 were thus secured. A few worn M. athalia and M. didyma were 

 also obtained. All this time a small Hesperid had been dashing 

 about : this we at first left severely alone, believing it to be the 

 common A. thaumas, but a chance capture apprise us of the 

 fact that it was A. actceon, and a fine series was soon obtained. 

 Butterflies are common enough, but they cannot compete with 

 the burnets, which are now out in full force. Zygcena meliloti, 

 Z. purpuralis, Z. lonicerce, Z. trifolii, and Z. filipendidce are all 

 about equally common, the latter being perhaps the commonest ; 

 Z. meliloti and Z. trifolii were getting worn. 



Our objective being the limestone hills, we had to leave this 

 Eldorado, and for about an hour our way led through a fairly 

 gloomy pine wood. Much to my astonishment, a species of 

 Melitaa was fairly common, together with C. arcania, all through 

 these woods. I captured a good many, and they proved very 

 variable, some striking varieties being amongst them ; but the 

 question is what are they — M. athalia or M. aurelia? I confess
