wedge-shaped sclerites in the transverse fissure 
of the cephalothorax. Mr. Cook dedicates the 
genus to Mr. Hubbard and the species may be 
called Hubbardia pentapeltis. 
Mr. W.G. Johnson read a paper on Isaac P. 
P. Trimble, economic entomologist, giving an 
account of Mr. Trimble’s life and exhibiting 
photographs taken at different ages and a large 
series of unpublished plates prepared under Mr. 
Trimble’s direction for a second volume of his 
work on fruit insects. The plates excited con- 
siderable interest from their excellence. 
Dr. Dyar presented a note on an external 
feeding hymenopterus parasite. This is a new 
species of the Ichneumonid genus Pammicra, 
which lays its eggs on a Nematine saw-fly 
larva, feeding upon black oak on Long Island. 
The parasite paralyzes the larva with its sting, 
lays two eggs upon its dorsum, and the para- 
sitic larve feed externally, remaining in the 
larval condition five days. 
Mr. Ashmead read portions of a systematic 
paper on the genera of the Hucharidz and pre- 
sented a new classification of the old family 
Chalcididse, which he will make a super-family, 
Chalcidoidea, containing fourteen families.

TORREY BOTANICAL CLUB, OCTOBER 12, 1897. 
No regular program had been prepared for 
this meeting, but notes detailing some results 
of summer’s work were presented by Drs. 
Rusby and Underwood, Mr. Van Brunt, Mrs. 
E. G. Britton, Judge Brown, Mr. Eugene 
Smith, Mr. M. A. Howe and Miss Ingersoll. 
Dr. H. H. Rusby spoke of his work at the 
Kew Herbarium in identifying some 2,000 plants 
of two Bolivian collections. As an indication 
of how the Columbia University has grown in 
the last few years, he noted that in working up 
a similar collection four years ago he was able 
to determine but 5 or 6 % by comparison with 
the plants in this herbarium, while of the 
present collection nearly 50 % were identified 
by this means. He added that the herbarium at 
Kew is also growing rapidly, and in four years 
has added to its collections nearly half as many 
specimens as are in the Columbia Herbarium. 
Dr. Underwood remarked that the Kew

[N. S. Von. VI. No. 155. 
Herbarium is superior to the Paris Herbarium 
even in the plants of the French provinces. 
Of these, many are represented at Kew and 
not at all at Paris. 
Mr. Cornelius Van Brunt spoke of his journey 
to the Selkirk and Rocky Mountains of British 
America, making many photographs of new or 
interesting plants. 
President Brown described a precipice in the 
Shawangunk with an altitude of 2,200 feet, bear- 
ing pine trees on its summit only six inches 
high but with perfectly developed cones. 
Throughout the region Arenaria Groenlandica. 
was abundant in bloom from June to Septem- 
ber, most copiously in July. He remarked 
upon the abundance and profuse bloom of 
Gentiana quinquefolia, Kalmia .latifolia, Rho- 
dodendron maximum, Ilex montana and the 
Rhodora.

THE ACADEMY OF SCIENCE OF ST. LOUIS. 
AT the meeting of the Academy of Science of 
St. Louis on the 6th of December, 1897, fifty 
persons present, Mr. Julius Hurter exhibited 
specimens of a considerable number of reptiles 
and batrachians, mostly of Southern origin, 
which had been collected by him during the 
past season, and were additions to the known 
fauna of Missouri. Among the more interesting 
additions were the cotton-mouth moccasin, the 
banded water snake, Holbrook’s water snake, 
the little brown snake, the Louisiana mud tur- 
tle, the chestnut-backed salamander (first de- 
tected west of the Mississippi River by Mr. Col- 
ton Russell), and the marbled salamander. 
Mr. H. von Schrenk exhibited a series of spec- 
imens and drawings illustrating some of the 
injuries inflicted on the trees of St. Louis by the 
tornado of May, 1896, showing not only the for- 
mation of double twig elongation and growth 
rings, but the exfoliation of the bark and the 
consequent drying-out of fifty per cent. or more 
of the wood through the trunk and branches in 
several species. 
One new member was elected, and one per- 
son was proposed for active membership.
