THE CANADIAN ENTOMOLOGIST 



ODONATA OP^ THE FRANCONIA REGION, NEW HAMPSHIRE. 



BY R. HEBER HOWE, JR., CONCORD, MASS. 



Mrs. Annie T. Slosson's captures of Odonata in Franconia, made now over 

 a decade ago, have already attracted odonatologists to a recognition of this 

 interesting region. Franconia is thus the type locaUty of Gomphus borealis 

 Needham, and Somatochlora minor (Calv.), and five of Dr. Scudder's species 

 were first described from the White Mountain region. It has been 

 difficult, however, to limit the scope of this paper to just the township, 

 and impractical to take a definite radius, for lying so near the Connecticut 

 Valle\-, a xQvy varied topographic region would be included, when it seems 

 more interesting and proper to make the paper one on the mountain and foot- 

 hill stations. I am. therefore, including the records made for the immediate 

 region of the higher White Mountains, a region I think often referred to by 

 Hagen and others on odonate labels as "White Mts." The list thus includes 

 the notable records and type stations of Dr. S, H. Scudder on Mt. Washington, 

 and at The Glen, and records of Dr. P. P. Calvert at Fabyan's, Dr. G. M. Allen 

 at Intervale in 1899, etc. 



My own collecting in this region includes one day's trip made in 1916, from 

 southern New Hampshire, north through the Profile Notch and south again by 

 the Crawford (Psyche 24:45-53, 1917), and during the past summer when I 

 was a resident of Franconia from June 24 to August 5, and during a two days' 

 trip on June 1 and 2. One of the interesting features of my list is, not so much 

 that 1 failed to find many species recorded by Mrs. Slosson over her long years 

 of collecting in the region, but that in one summer I should have taken a con- 

 siderable number of common species which it seems she certainly would have 

 found: facts indicating very probably changes or local extensions of insect 

 ranges in this region. 



Zygoptera. 

 Agrionid^. 



1. A or ion amatum Hagen. 



June to July. Mrs. Slosson writes me, "There are not many bodies 

 of Avater around Franconia where he was not to be found twelve years 

 ago,^ — Pond Brook, Streeter Pond, Black Brook, along the Gale River, 

 everywhere." Dr. Allen found it common at Intervale by the river, 

 last seen on July 29. This species I was unable to find at all in the 

 entire region. 



2. A or ion cequahile Say. 



June to July. Dr. Allen found it along the Saco River from June 27 

 to July 3. 



3. Agrion maciilatiim Beauv. 



June 20 to 27. 



I found it common about the brooks leading out of Echo and Profile 

 Lakes, uncommon on Black Brook, and at Pearl Lake, Lisbon. It was 

 taken at Intervale by Dr. Allen from June 20 to July 12. There is a 

 male in U. S. N. Museum taken at Franconia by Mrs. Slosson. 



January, 1919
