Note hh — BOOK VIII.

It being an Instance somewhat out of the Way, I shall pitch upon it for an Example here, viz. The gouty Swellings in the Body, and the Branches of the Blackberry-Bush; of which Malpighi hath given us two good Cuts in Tab. 17. Fig. 62. The Cause of these is manifestly from the Eggs of Insects laid in (whilst the Shoot is young and tender) as far as the Pith, and in some Places not so deep; Which for the Reasons before-mentioned, makes the young Shoots tumify, and grow knotty and gouty.

The Insect that comes from hence is of the former Tribe, a small, shining black Ichneumon-Fly, about a tenth of an Inch long; with jointed, red, capillary Horns, four long Wings, reaching beyond the Body, a large Thorax, red Legs, and a short, heart-like Belly. They hop like Fleas. The Males are less than the Females; are very venereous, endeavouring a Coït in the very Box in which they are hatch’d; getting up on the Females, and tickling and thumping them with their Breeches and Horns, to excite them to Venery.
