PROCEEDINGS OF SCIENTIFIC SOCIETIES. 185 
Miss Eleanor A. Ormerod, of Dunster Lodge, Spring Grove, Isleworth, 
was ballotted for and elected a member. 
Mr. McLachlan called attention, with reference to Mr. Mansel Weale’s 
observations on Termes trinervius made at the last meeting of the Society, 
to a statement in Hagen’s “‘ Monographie der Termiten ” (‘ Linnzea Kntomo- 
logica,’ xiv., p. 86), given on the authority of Osten-Sacken, respecting 
Termes Rippertii of Cuba, the soldiers of which species are said to exude a 
drop of clear liquid from the point of the head when handled. Mr. 
McLachlan said that it was interesting to find that Mr. Mansel Weale’s 
observations had confirmed those formerly published. 
Mr. F. Grut exhibited, on behalf of the Rev. T. A. Marshall, a collec- 
tion of insects made by the latter in the Windward Islands, and read a 
letter which accompanied the collection. 
Mr. F. Smith exhibited a series of specimens of a species of ‘“ Har- 
vesting Ant,” sent to Mr. Darwin from Florida, U.S., by Mrs. M. Treat. 
On comparison, the Ant appears to be identical with the species from Texas, 
Myrmica barbata, the M. molifaciens of Buckley. Three phials containing 
ants were sent, one containing specimens gradating from large soldiers to 
small workers, all having- acutely dentate mandibles. A second phial 
contained ants varying in size, but all with mandibles having rounded 
teeth; in the specimens in the third phial the teeth were obsolete. 
Mrs. Treat’s letter did not make it clear whether intermediate forms of 
teeth are to be found in nests, or whether it is to be understood that three 
- distinct races exist in colonies, each being thus constituted for the per- 
formance of distinct functions. Mr. Smith stated that he had entered 
into correspondence with Mrs. Treat, and hoped shortly to obtain further 
information. 
Mr. Alexander A. Berens exhibited a pair (male and female) of Thestor 
Mauritanicus, Staud., taken on the Atlas Mountains, in Algeria, in 
April. 
Mr. M‘Lachlan exhibited a coleopterous larva (probably a Buprestis or 
Longicorn) belonging to the tribe known as “ coffee-borers,” sent from 
Zanzibar by Dr. Kirk. He also exhibited a portion of a stem which had 
been bored into by the larva, and which was especially remarkable on 
account of the presence of a series of holes nearly equidistant, and bored 
in a direction perpendicular to the main gallery. These holes, which 
opened a communication between the inner gallery and the outer air, were 
of a conical shape, the inner opening being the widest, and Mr. M‘Lachlan 
suggested that they were made by the insect for the purpose of ventilating 
the gallery. 
Mr. Smith remarked that he had bred numbers of a Longicorn beetle 
(Saperda populnea), and had frequently observed in the shoots of the aspen,
