FOUR DAYS AT THE DRACHENFELS. 
BY R. C. BR. JORDAN, M.D. 
Having a few days that could be spared from work, I thought that 
I would take a ramble by the Rhine, which had not been visited by me 
for many years; and the 10th, 11th, 12th, and 13th of June were spent 
at Konigswinter. These days were given up entirely to entomology, 
and, therefore, a slight account of them may be of some interest. In 
1853, I had an afternoon of insect-hunting in the wood just below the 
Castle of the Drachenfels, on the 24th of August: the Lepidoptera 
then captured were Lycena Dorilis (common), Smerinthus populi (one 
larva), Callimorpha Hera, Hypogymna dispar (the males flying very 
actively on the wing like Lasiocampa querciis), Cosmia trapezina, 
Livula sericealis, Pyrausta punicealis, Pterophorus pentadactylus, Minoa 
euphorbiata (common), ELubolia meniaria, E. bipunctaria, and Campto- 
gramma bilineata. 
We came to the excellent Hotel de l’Europe on the evening of 
the 9th of June, and early on the morning of the 10th, my little girl 
and I set off for the Drachenfels. The day was not good for entomo- 
logy, there was a high wind which just kept off the rain that otherwise 
would have fallen; it was, however, favourable for walking, which, 
perhaps, made the scales of the balance even. We first crossed the 
railroad and went up the little path amongst the vineyards, and at the 
first wood began to entomologize; Lithographia Penkleriana was very 
At the end of this little wood were plenty of broom plants, on beating 
which, Cemiostoma spartifoliella appeared in clouds, and this was the 
case wherever broom occurred in the district; we then emerged on a 
hilly field with a little round summer house on the summit, here a bad 
abundant amongst the oaks, and Harpella Geoffrella was also common. 
specimen of Satyrus Megera occurred, and afterwards in some plants | 
of tansy, amongst the corn, Dicrorampha plumbagana was met with ; 
then followed the wood surrounding the castle, and here the larve of | 
Hypogymna dispar were common enough for us to find two on one oak | 
wreath ; amongst the undergrowth of shrubs were abundance of plants 
of Populus tremula, these had many galls upon them, and Saperda | 
{ 
populnea was so frequent as to become troublesome ; Huonymus euro- | 
peus was also plentiful, and its branches were in great measure stripped - 
by the larvee of Hyponomeuta evonymella; there were very numerous 
pyriform galls on the leaves of the beech; here Pygera bucephala 
occurred, asleep, of course.
