maxniQfa(a) nidificates in ports and rails. Jlph violacea, as \vc 

 Jcarn from RcaumuiY^A conftruas cuiious cells for its young, of 

 feveral ftories, in the fupports of efpnlicr trees. Ap:sfurcala(c) 

 makes fimilar cells in decaying wood. Many other infeas of this 

 eiafs, particularly Spheges^ and illegitimate Vefpa, emerge from cylin- 

 drical holes in trees and pofts, in which they were nourilhcd in 

 their larva ftate. 



Of Dipterous infecls, the Tipula peSlin'icornh, fingular for the 

 branching antenna; of the male, and many other fpccies of that 

 genus, in their larva ftatc, inhabit putrefccnt wood (d) : and a nu- 

 merous army of the Om/cus Jfellus, to name no other iiifea in the 

 ylplera clafs, is generally to be met with in thofe parts of decaying 

 trees under the bark, which are deferted by other infeas ; upon 

 which, from its faw-duft-like excrement, it appears to feed. 



Having gone over the other clafles, it remains that we mention 

 the devourers of wood amongft the Cokoptera. Foremoft in the 

 ranks comes the gigantic Lucanus Cervus, whofe larva feeds upon 

 the decaying wood of the oak (ej and the elm. In the latter is 

 alfo found x.\\e Lucanus hiermis (f). The aQi aftbrds nourilhment 

 both to Lucanus parallelipipedus and L. cylindricus. (Scarabaus cylin- 

 dricus of Linn, but furely a true Lucanus.) The feveral Ipecies of 

 the genus Ips (Boftrkhus Fab.) feed upon timber between the bark
