i 
angustata, H.-S., new to Britain, which he had captured by 
sweeping near Cisbury, Worthing. The insect is rather 
closely allied to the common Monanthia cardui, L. 
Mr. M‘Lachlan exhibited a species of Halticide, which had 
been sent to him by Mr. D. Morris, Assistant-Director of the 
~ Royal Gardens, Kew, who had received them from Mr. J. H. 
Hart, of the Botanic Gardens, Trinidad, with a note to the 
effect that they had attacked young tobacco- and ege-plants 
badly in that island. Mr. Jacoby had, with some reserve, 
given as his opinion that it might possibly turn out to be 
Epitrix fuscata, Duy., a species which had been described 
from Cuba. 
The Rev. H. 8. Gorham exhibited a number of beetles 
lately captured in Brittany, including Diachromus germanus, 
L., Onthophagus taurus, L., Hister sinuatus, Ill., and other 
species which are exceedingly rare, or altogether wanting 
in Britain, and yet occur very commonly in the North of 
France. 
Mr. Enock exhibited specimens of the Hessian Fly bred 
by himself and mounted for the microscope. 
Mr. W. White exhibited, on behalf of Mr. G. C. Griffiths, 
two living larve of Hndromis versicolora in their third stage, 
illustrating their strongly protective resemblance to the 
catkins and leaves of their food. Mr. Griffiths had noticed 
it to be the habit of the insect at this period to congregate 
at the ends of the twigs of birch, with their heads nearly 
always in the direction of the end of the spray: in their 
favourite resting attitude, in which the fore part of the body 
was elevated at a curve, they bore a great similitude to the 
young catkins. On more than one occasion he had also 
noticed, when feeding a number of them, that one or two 
ejected from the mouth a greenish fluid, which he concluded 
to have a protective value, and to be produced under sudden 
alarm; but he had not been able to induce them to repeat 
the act. It was, however, a common habit for them to 
swerve their heads sharply round in a threatening manner 
whenever the anal hump was touched. As the specimens 
exhibited had just passed out of the second stage, they had 
lost the character of chief interest in their ontogeny, for in
