REMARKS UPON THE DISTRIBUTION OF ANIMALS AND PLANTS. 563 



THE DISTRIBUTION OF INSECTS. 



At my request, Mr. C. P. Whitney, of Milford, visited the southern 

 part of Cheshire county, in the early part of August (1874), with the view 

 of ascertaining whether some of the more northern species of insects 

 extended farther south than the latitude of Milford. The season proved 

 to be an unfavorable one for observing characteristic species, partly 

 because of stormy weather, and partly because the most peculiar forms 

 usually make their appearance earlier in the summer. 



Concerning the fauna of Mt. Monadnock, Mr. Whitney writes, 

 "Although about the summit I found flora corresponding to the sub- 

 alpine of the White Mountains, I met with no insects except such as 

 are found below, and of those but few." 



Concerning the insects south of the mountain he writes, "To the 

 south of the mountain in Jaffrey, Rindge, etc., I found Minois A lope 

 (which I can hardly regard as Canadian) in abundance; also, Basilar- 

 chia ArtJiemis, Grapta Faunus (Polygonia of Scudder), y. album, A. 

 bombyx, and Ctenucha Virginica. 



"Although owing to the continued rainy weather I met with but little 

 success, I am satisfied those towns possess a more northern fauna than 

 Milford and its vicinity, whether enough so to place them in the Can- 

 adian region (if, indeed, a division is practicable), I cannot determine. 



"I wish to call your attention to a few instances which conflict more 

 or less with Mr. Scudder's text. The numbers are those of his list. 



"4. Nepliele is not found in the southern part of the state. 



"11. Mr. Hutchinson has taken a specimen of interrogationis at Han- 

 over. 



"24. I have seen Aphrodite in the sub-alpine region of Mt. Wash- 

 ington. 



"35. Edwardsii has never been taken here [Milford]. 



"69. Vialis is common in the lowlands of this vicinity; and I have 

 found it abundant both in the Glen (White Mountains) and at Dixville 

 notch, in the northern extremity of the state. 



"71. Paniscus (Mandan) I have taken at Colebrook; and Mr. Mor- 

 rison took one specimen in the Glen. 



"73. Massasoit has not been seen here.
