Exhibitions, &e. 
Mr. Enock exhibited male and female specimens of a spider 
received from Col. Le Grice, R.A., who had captured them at 
Folkestone in May last. They had been submitted to the 
Rey. O. Pickard-Cambridge, F.R.S., who identified them as

was first seen on May 27th by Master W. Kerr, who 
pointed it out to Col. Le Grice, and he captured it; a female 
was next seen by Mr. Kerr, sen., and captured by Col. Le Grice. 
The males of this beautiful spider are found during the 
brightest sunshine, sitting on bits of chalk scattered about on 
sloping banks facing south; the female is more retired in her 
habits. The bright scarlet hairs which surround the four 
anterior eyes of the male make this spider the most strikingly 
beautiful of all the British Salticide. 
Mr. Enock also exhibited specimens of Merisus destructor 
(Riley), an American parasite of the Hessian Fly, bred from 
British specimens of that insect. He said that in the autumn

Fly from puparia collected on the 5th and 8th of August, four
