opposed margins of the lateral lobes inrolled, moderately well 
marked, each about 4 spinulose. 
On the middle of the sides of the abdomen are two longitudinal 
brownish bands, below which the sides are paler. 
One specimen, collected by Mr T. H. Hankinson near Varna, . 
2 miles above Ithaca, from a cold spring brook near to the place 
of its confluence with Fall creek, July 13, 1901. I collected a 
specimen of the same species in Six Mile creek a mile southeast 
of Ithaca in April 1896. I innocently placed it in a breeding cage 
in which were a few Gomphus nymphs burrowing in the mud of 
the bottom; for I did not then know that Gomphus nymphs go 
foraging in the territory above them. The next morning there ~ 
remained in my cage but a fragment of the Somatochlora nymph, 
consisting of the dorsal wall of the abdomen and the abdominal 
appendages. This fragment I preserved, for I had recognized 
that the nymph was a new one, and I find it quite sufficient for 
recognition as the same species described above. The dorsal 
hooks are perhaps twice as long in this species as in 8. elon- 
gata. Since S. elongata is the only species known from 
Ithaca, I am unable to say to what species this nymph may 
belong. 
Somatochlora sp. no. 3 
A single nymph, not fully grown, sent me from Raleigh N. C. 
by Mr C.S. Brimley. It is a short, flat species with very wide, 
abruptly truncated abdomen. Somatochlora tene- 
brosa has been collected at Raleigh, and the nymph may be- 
long to that species. 
Length 16mm, abdomen 9mm, hind femur 5.5mm, antenna 
6mm; width of head 5mm, of abdomen 8mm. In form and orna- 
mentation of the head and front part of the body and in arma- 
ture of the labium similar to the preceding species. Differs in 
the relatively greater width and flatness of the abdomen, in 
having the lateral spines of segments 8 and 9 wider, flatter, 
blunter and straighter at tip, and triangular in outline as seen 
from above; appendages shorter and more retracted, the tip of 
the laterals hardly surpassing the level of the tips of the lateral 
spines of the ninth segment (surpassing these by half their length 
in the preceding species). Dorsal hooks shorter, on segment 4 
a mere rudiment, on 5 small, on 6-9 better developed, spinulose 
on superior and straight and bare on inferior margins.
