266 THE CANADIAN ENTOMOLOGIST. 



The pupae possess the power of movement to an astonishing degree, 

 and when disturbed back quickly downward into their burrows. This is 

 so characteristic of them that we were obliged to approach a tree rather 

 carefully, and quietly tear away the grass and debris around the base with- 

 out disturbing the cocoon if we wanted to be sure of our specimen. I 

 lost some entirely, and cut others in two just as they were backing from 

 their cocoon into the burrow in the tree. Again, so many pupae backed 

 out of their cocoons after the latter were removed that they dried out and 

 failed to transform. 



Tiie records of the appearance of the moths are as follows : 



Many empty pupa-cases found May 4. 



One male May 8. 



One female May 8. 



One male May 9. 



One female May 10. 



One female May 11. 



One male May 13. 



Some are yet to transform (May 18). 



These borers must injure the native Persimmon much more than a 

 Peach-tree borer does a Peach tree, although I found no borers in large 

 trees. They seemed to be confied to the young and small trees. 



It is also an interesting fact that we were unable to find a single borer 

 in the cultivated Japanese Persimmon trees standing in close proximity to 

 the wild infested trees.

Among the mosquitoes sent in during the collecting period of 1906 

 in the U. S., was an Anophelina which has caused me some perplexity. 

 The general colouring at once suggested one of the sifiensis group, and it 

 occurred to me that some joke had been perpetrated, so I wrote the 

 collector, asking if it were i)0ssible that any Philippine mosquitoes had 

 gotten in with these. He, however, said it was quite impossible, as he had 

 no P. I. mosquitoes with him when this collection was made. No speci- 

 mens resembling this had previously been received from the U. S., so that 

 I was somewhat reluctant at first to accept it, but as closer study shows it
