NATURAL HISTORY NOTES IN HOLLAND. 15 
to understand that for the small sum of “twee gulden” they 
would take us to our own boat, otherwise, if we remained where 
we were, the tide would rise up to our breasts. We paid our 
money, and they kept their bargain. Of course we did not 
venture there again. 
The following insects were procured at Valkenswaard, in the 
identification of which my friend Mr. Naylor has kindly helped 
me :— 
CoLEopTEeRA :— Cicindela campestris, hybrida, and Germanica; 
Silpha thoracica, nigrita, and reticulata; Pterostichus dimidiatus ; 
Carabus granulatus and auratus; Lina populi; a species of 
Galerucide, and also one of Hlateride, not determined yet; 
Coccinella 14-punctata. 
OrTHOPTERA:—Acheta campestris. 
HyMENopTEeRA:—Vespa crabro. 
The caterpillar of the Goat Moth, Cossus ligniperda, was 
taken on some willows on the banks of a pond, and that of the 
Poplar Hawk Moth, Sphinx populi, was also obtained. Four 
dead specimens of the Emperor Moth, Saturnia pavonia-minor, 
were picked up on one of the heaths, and the Buff-tip, Pygera 
bucephala, was very common. Near Dordt we found some hedge- 
rows and gardens completely devastated by the Forty-spot Moth, 
Hyponomeuta padellus. Without exaggeration, in several hundred 
yards of hawthorn hedge, there was not a single leaf; it was com- 
pletely covered by their webs and caterpillars. Hundreds of 
apple-trees, too, were in the same state. On the hawthorn there 
were also mixed with them a considerable number of caterpillars 
of the Gold-tail, Porthesia auriflua, but we did not see them on 
the apple. We also took the Drinker Moth, Odonestis potatoria, 
on the buckram grass near the Savi’s Warbler nest, and of 
other Lepidoptera :—Cataclysta limnata, Lomospilis marginatus, 
Camptogramma bilineatus, Tortriz viridana, from Willemsdorp: 
Clisiocampa neustria, from Dordt. 
Amongst the Neuroptera we procured specimens of Panorpa 
communis. 
We collected a few Mollusca, amongst which were identified 
Planorbis corneus and carinatus, Limneus stagnalis, Helix 
nemoralis and hortensis, and Paludina vivipara.
