METHODIC HABITS OF INSECTS WHEN VISITING FLOWERS. 8l 



C. arcania was fairly plentiful on the Marienbad road. 



C. davus was not numerous. 



A few specimens of Syrichthus serratulce were taken on the 

 Marienbad road, on July 10th. 



Hesperia linea and H. sylvanus were very common in suitable 

 localities ; the first preferring the woods, the other the open 

 country. 



The Heterocera we never attempted to work, but observed 

 the following :— Sesia culiciformis, Procris statices, Zygcena 

 minos, Z. trifolii, Z. Jilipendidce, Euthemonia russula, Chelonia 

 plantaginis, C. caja, Bombyx quercns, Boarmia repandata, 

 B. abietaria, Melanippe cdbicillata, M. hastata, Anaitis plagiata, 

 and many others. 



The climate of Carlsbad is subject to sudden and great 

 variations of temperature, but we were exceptionally favoured. 



The cost of living, lodging, &c, is moderate up to the middle 

 of July ; after that the English season begins, and everything 

 costs about double. 



I ought to mention that a friend told me that Vanessa antiopa 

 may be taken at Carlsbad occasionally.

[It having been thought desirable that the readers of the 

 'Entomologist' should be provided with a summary of the 

 conclusions arrived at as the results of my somewhat lengthy 

 observations on this subject, which have already appeared, I 

 have pleasure in publishing the following remarks, which are 

 extracted from a paper of mine, read before the Linnean Society 

 on March 1st, 1883, and published in the Society's Journal 

 (' Zoology,' vol. xvii., p. 186). As the details of my observations 

 have already been given so fully, it has not been thought neces- 

 sary to reproduce the tables published by the Linnean Society, 

 in order to show more clearly at a glance the result of the 

 observations, although the following remarks are, to some
