A day with Chrysophanus dispar var. rutilus. 



By E. M. DADD, F.E.S. 



July 18th, 1909, was a sunny but windy day, bat, in spite of the wind, 

 I decided to go to Finkenkrug, as I was desirous of getting females of 

 Lycaena alcon. This species is very local in the Berlin district, as its 

 foodplant, Gentiana pneumonanthe, is confined to marshy meadows. 



The Grosse Laake, at Finkenkrug, is one of the chief localities for 

 the gentian, and it was here, some years ago, that I discovered the 

 larv® of Adkinia graphodactyla feeding on the gentian flowers. How- 

 ever, the search for L. alcon proved abortive, not a single specimen 

 being seen ; perhaps I was too late. Pohjommatus amandus and 

 Cyaniris semiargus were perfect wrecks, only a few possible females of 

 Loweia alciphron and Chrysophanus Idppothoe were left, scarcely a 

 Melitaca was to be observed, and only the abundance of Brenthis ino 

 $ from red to deep bluish-black compensated somewhat for one's 

 efforts. But the wind which continued to increase in strength, soon 

 made collecting impossible except in sheltered corners. 



Having secured a fair series of B. ino $ , I decided to take a look 

 at the Chrysophanus rutilus ground, which is a water-meadow beside 

 a small stream overgrown with reeds and sedges, and, generally speak- 

 ing, impassable. On the way I had to traverse a small portion of 

 bushy woodland, and here that extraordinary skipper Heteropterus 

 worpheus was not uncommon ; also a few Araschina var. prorsa and 

 Euyonia polychloros were about. 



On arriving at the meadow where C. var. rutilus is to be found, I 

 was pleased to see that it was dry enough to work, and it was not long 

 before the first male rutilus was observed on a thistle-head. Mean- 

 while the wind so increased in power that flight was out of the 

 question for butterflies, but, probably owing to this circumstance, I 

 made a very good bag of the species, seven males and eight females. 

 "With one exception, they were all seated on thistle, scabious or rag- 

 wort flowers, and were so intimidated by the wind, that one could 

 have picked them ofi' with the hand. 



Unfortunately, the males were somewhat worn, but the females 

 were in grand condition. Besides C. var. rutilus, Heodes viryaureae 

 was in countless numbers, and a few females of C. hippothue, Loweia
