SOME OLD CORRESPONDENCE BETWEEN HARRIS, SAY AND 



PICKERING.— VII. 



[PICKERING TO SAY.] 



Salem, Nov. 14, 1S25. 

 Dear Sir, 



I received your letter, 

 dated Oct. 12th, by mail in due season : 

 of that white Pieris I have but a single 

 specimen which is, I believe, a male, 

 though it is so much injured that I will 

 not be certain about it ; it does not 

 apparently differ from that which I sent 

 you which is as good a specimen as 

 could be procured; as the species 

 occurred frequently and within a short 

 distance I most probably saw both 

 sexes, and if there were any difference 

 between them, at all conspicuous, I 

 should have observed it : my attention 

 was so much distracted by botany 

 during my short visit to the White hills 

 that I neglected the insects more than I 

 ought to have done — and besides my 

 whole collection of minute insects was 

 lost, so that I did not bring home 

 above a hundred species. Of these I will 

 mention a few trusting that you will 

 excuse me, if they prove to be familiar 

 to you, as my opportunities of becoming 

 acquainted with American insects are 

 at present very limited, amounting 

 principally lo Turton's Linnaeus. I 

 expect however to get access to your 

 publications this Winter. 



A species of Nothiophilus (not dis- 

 tinguishable by a short description from 



N. aquaticus of Europe) occurred on 

 the bald part of the mountains to the 

 very apex of Mount Washington. At 

 the same locality I took a Thanasimus, 

 differing from the description of T. 

 formicarius in having the anterior fourth 

 of the thorax black — its length is a 

 little over a fifth of an inch. 



1. The perfect insect, line above natural size. 2. 

 The hind tarsus. 3. Last joint of thetarsus. 4. Front 

 view of the head. 5. Elyt. 



On the road through the Notch I 

 found a Cimbex — length of the body 

 nearly one inch, tergum black-blue 

 with a yellow spot on each side of the 

 5, 6, and 7 segments, wings fuscous at 

 the middle and tip, it is a female. 



The insect of which I send you a 

 sketch* I am unable to refer to any 

 genus I can find described ; it belongs 

 to the family Cantharidae ; it differs from 

 Lytta in having the head gradually tap- 

 ering behind the eyes into an indistinct
