1917] Howe—Notes on New England Odonata 45 
about 528 microns. Thorax long and narrow, about 480 microns 
wide in middle; anterior legs about 704 microns behind head; an- 
terior femora curved, convex above, concave below; their tibize 
rather short (about 288 microns), with a single long spur; their tarsi 
long, the first joint longer than next three together, and strongly 
curved; hind femora extremely broad and flattened, the summit 
of the curve about half-way between base and middle; abdomen 
with a rather long petiole. 
Burmese amber, from R. C. J. Swinhoe. In the same slab as the 
type of Cryphalites rugosissimus, and 24.5 mm. from it. Related 
to Scleroderma (?) quadridentatum, which may possibly belong to 
Apenesia, but on account of the black abdomen and various struc- 
tural characters surely not its male.

Since Dr. P. P. Calvert’s List was published in October, 1905, the 
following published corrections and additions have been made: 
Argia apicalis (Say) Selys. recorded from Maine by Dr. 
Calvert on the authority of Prof. Harvey was expunged 
by Dr. Calvert following an examination of the Harvey 
specimens by Mr. Williamson (Ent. News 17: 31. 1906). 
Argia mesta putrida (Hagen) was shown by Mr. E. B. Wil- 
liamson to be synonymous with Argia mesta Hagen 
(Ent. News 23: 200. 1912.) 
In Dr. E. M. Walker’s “The North American Dragon-flies of 
the Genus A’shna (Univ. Toronto Studies, Biol. Series, 1912) the 
following New England records for the genus were made: 
Aishna cerulea septentrionalis Burm. 
N.H. White Mts. (Scudder) 
Aishna juncea Linn. 
N. H. White Mts. (Scudder)
