Note. — This insect appears to inhabit New Holland and 

 New Zealand, according to Fabricius and Christius ; America also; 

 but its size there is 15 lines, while in Europe it is seldom more than 

 half that length ; though very similar, may they not be distinct spe- 

 cies ? The O. luteus of Gravenhorst is exceedingly common in this 

 country. 



3. Ophion undulatus.
