THE CANADIAN ENTOMOLOGIST. 1; 



speak from my own experience, which is fully corroborated for the American 

 species by two entomologists here. In Kahlberg, Mr. Schindofsky came 

 to show me the insect in the field, and told me he was sure I would pass 

 by it without seeing it. On a rustic fence I really passed it ; the speci- 

 men had been sitting on the same place at least for two hours, and 

 matched perfectly with the color of the bark of the fence rail. I threw it 

 in the air to see it fly. It fluttered in the most lazy and awkward manner, 

 until it tumbled in a potato field very near ; when I took it up again, 

 without any resistance on its part, the same show was experienced. Per- 

 haps they are more agile during the night. Tha-not uncommon presence 

 of the insect in the same place was observed during the last seven years 

 before I left Europe. As later, by order of the Government, a country 

 road was laid just through the sandy hill where the insect lived, it may 

 have been destroyed, but I have had no information about it. As I have 

 been connected most intimately since the first discovery of this species in 

 Prussia, with the question, " introduced or not," I beg leave to give my 

 objections to the statement that it is introduced, which seems to be an 

 impossibility. 



The following interesting species of an Ascalaphide, described by Ae 

 many years ago, but not yet published, has the same distribution as 

 Acanthaclisis Ajiiericana^ going even further to the north.
