19191 Eowe-Dragon-Flies from Wareham, Mass. 65 A LIST OF DRAGON-FLIES COLLECTED AT WAREHAM, MASS., DURING THE YEARS 1911 TO 1913 BY MR. OUTRAM BANGS.
BY R. HEBER HOWE, JR.
Thoreau Museum of Natural History, Concord, Mass. The following rather remarkable list of Odonata is the result of my determination of a collection made by Mr. Bangs at Wareham, Massachusetts, and the material on which it is based is now dis- tributed through the general collection of the Museum of Com- parative Zoology, Cambridge, Mass. Access to the specimens was obtained through the kindness of Mr. Nathan Banks, and per- mission to publish the list secured from both Mr. Banks and Dr. Samuel Henshaw. Several duplicates are in the author's col- lection, and that of the Boston Society of Natural History. Though Mr. Bangs is not familiar with the group Odonata his trained naturalist's eye made it possible for him to collect a very large percentage of the species that occur, and the list is deficient only in the Zygoptera or smaller Damsel-flies. Mr. Bangs has provided annotations of several interesting species. Zygoptera.
1. Agrion cequabile (Say). "Occurs only, so far as I know, along Eagle hill river. I got one."
2. Agrion maculatum Beauv. June 2-9. Several specimens. 3. Lestes eurinus Say. June to July 30. Several specimens. 4. Lestes unguiculatus Hagen. One specimen. 5. Lestes rectangularis (Say).

NOTE ON THE GENUS LIOBRACON, WITH THE
DESCRIPTION OF A NEW SPECIES
(HYMEN-
OPTERA; BRACONIDB).
BY CHARLES T. BRUES,
Bussey Institution, Harvard University.
In a small collection of Parasitic Hymenoptera collected in Hayti several years ago by Dr. William M. Mann, I have found several specimens of the insect described by Cresson as Brawn distinctus in his "Hymenoptera of Cuba. " This proves to belong to the genus Liobracon Szkpligeti, to which several South American species have hitherto been referred. In addition there is a second species taken by Dr. Mann which is described below. Liobracon Sdpligeti.
