To this I have nothing to add but a new locality for the last named, and a partial life history of it. One other species occurs farther southward, and is almost certain to be taken in this state eventually, and is therefore included among the species listed below. Somatochlora elongata Scudder Plate 21, flg. 15 1866 Cordulia elongata Scudder, Bost. soc. nat. hist. Proc. 10:218 1895 Soma t oc hi ora elongat a Calvert, N. Y. ent. soc. Jour. 3:46 (listed from Ithaca) The few imagos I saw of this species were flying with great swiftness about the borders of Bone pond. The single nymph I found was taken. Fig. 23 Somatochlora elongata Scudd., end of abdomen ; d and e of male ;/of female from Litde Clear pond, -as stated above, and transformed July 5. A cast nymph skin was found later in the season on the north side of the outlet of Little Clear, sprawling on a bed of moss but a few inches above the water Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum; New York State Museum.
