5^2 Dr. Roxburgh’s Account of 
Mouth, on the middle of the bread:, between the firft pa!# 
of legs, which the little animal projects oil being in- 
jured, otherwife it cannot befeen. 
Trunk and Abdomen, oblong, comprefl'ed, tapering equally 
towards each end, eroded with twelve annular fegments, 
margins very flat, and feem to be marked with a double line. 
Extremities. 
Legs, fix, running, does not jump. 
Wings , none. 
Tail, two (lender white hairs, as long as the antenna, 
with a white point, which may be called the rump, 
between them. 
Pupa ■: the duration and peregrinations of the larva feem very 
(hort and confined ; for, in a few days after ifluing from 
their cells they fix themfelves oil the fmall, but hard, woody 
branches of the tree they were produced on ; it feeming 
impoffible that they can in this ftate tranfport themfelves 
to any other. About the end of December, or beginning 
of January, they have done ifluing from their cells, and 
are flicking faft to the branches, regularly with their 
heads towards the extreitiity of the branch. The legs, 
antenna, and tail, are now entirely gone; Their progrefs 
through this ftate is flow, requiring about three months. 
Sooft after they have fettled themfelves, they become 
covered with a hard, brittle, garnet-coloured cruft, fimi- 
lar toTthe lac of which the Cells are made, but of a 
brighter colour. They retain only a rude refemblance of 
their former ftiape. About the end of March they have 
acquired three or four times their original fize ; a fmall, 
round lid or cover is flow obferved at the lower part, 
which opens, but does not always fall off, and gives a 
retrograde paflage for the fly, now in its perfect ftate.
