groiaiids, I have twice done it to you ) the fatisfaSioo of ao 
Anfwertomy loth §lucere^ by him fjefolved negatively: It is 
Crue, the fwarms of ih^ Ichneumons ^ coming out of the fides 
of Gaterpillarsj do iramediatly make themlelves up into bun- 
ches y and each particular Theea , from the Cabbage-Cater- 
pillar (for example,) is wrought about with yellow filk, as 
thofe from the black and yellow-jf-^^'^?^*^^- Caterpillar with

LmC9lnJhireAiQaths^ which are affixed to Bents or other plants.

lar equivalent to the jWm?ifilk=worm 5 but having cat them 
in two, and expected to have found a Caterpillars Ckryfalis ixx 
the middle, there prefented themfelves a (warm of Ichneumons^ 
Thefe are as large many of them as my thumb, that is^at leaft 
four times bigger then the FoUiculus ot Egg-bag of anyEn- 
glifli fpider that I ever faw yet. By good fortune I have not 
thrown away the boxes, wherein I made the Obfervation con-

I have had them in feveral boxes, fome 8, fome 10, fome 12 
days in Vermiculo , feeding upon the very cakes of Spiders^ 
eggs, before fhey wrought themfelves Thecas for further 
change* and they feldome exceeded the numberof 5 to one 
cake of Eggs , &c. fo that you may aflure Mr. Willoughbj^ 
this is no conjecSture , but a real obfervation accompanied 
with more circumftances^ than I am wiUiog at prefeot to re^ •
