a close room, and permitting them to fly to the windows, I caught 
them again with a wine-glass and a card, fed them with.sugar, 
and thus preserved them till their parasites were disclosed. I 
had not the pleasure to see them emerge, but found them soon 
after. I obtained four in this way, and brought several nests of the 
Vespa into the house, taking them in the night when all the inhabi- 
tants were at home, in the hope of obtaining more; but I got no 
living ones. This year I have not taken one, for want of time to 
attend to it. | 
* All I know of this Stylops was picked up in a few days that I 
passed at my little place at Newbury, about forty miles from 
this. The form of the larva will be seen at fig. 1. and fig. 3. 
In the feeding state the head is near the base of the abdomen of 
the wasp, as I found by dissection. When the feeding state is 
passed, it is easy to conceive that it turns, and with its flattened 
head separates the membrane which connects the abdominal 
scuta, and protrudes: itself a little way, accurately closing the 
aperture, which is but just large enough to admit it. All this. 
‚time the wasp is active, and associates with its companions. 
When just protruded the head of the larva is of a pale brownish: 
colour; by degrees it assumes a rounder form, and becomes 
almost black. 
* 'The chrysalis state ensues; but I suspect that only the pit 
exposed to the air, and that immediately under the Pen. of 
tlıe abdominal ring, becomes hard. 
* My four Stylopes, I concluded at the time of "acht the 
figures, were males; they were all alike. "The last segment of 
"the abdomen in the male of the larger Cicade is joined to the 
penultimate one somewhat as in this; but in Cicada it is only a 
kind of operculum. In the Stylops the last portion of the abdo- 
men appears to be an organ of importance in its ceconomy :. it 
N 2 terminates
