2 jo Dr. Roxburgh’s Account of 
To-day the female infeCts continue iffuing in great numbers, 
and move about as before. 
Dec. 7. The final l red or female infers, areftill more nume- 
rous, and move about as before. The winged or male infeCts, are 
(till very few, but continue aCtive. There have been frefh leaves 
and bits of the branches of Mimofa cinerea, and Mimofa intfia, 
put in to them. They go over them indifferently, without 
(hewing any preference or inclination to work, or to copulate. 
I opened a cell, from whence I thought the winged flies had 
come, and found feveral (eight or ten) (truggling to (hake off 
their incumbrances. They were in one of thofe utriculi men- 
tioned before, which end in two mouths, (hut up with 
fine white hairs; but one of them was open for the exit of the 
flies ; the other would, no doubt, have opened in due time. 
This utriculus I found now perfectly dry ; and could plainly 
fee it was divided into minute cells, by exceedingly thin mem- 
braneous partitions. I imagine, before any of the flies made 
their efcape, it might have contained about (ixteen or twenty. In 
the minute cells, with the living flies, or from whence they had 
made their efcape, were fmall dark-coloured comprefled grains. 
March 26, 1790, I found fome branches of the fame fort of 
Mimofa, with numbers of the minute red hexapodes, men- 
tioned in December (feemingly in their pupa (fate), adhering 
to them. They are of various fizes, from half a line to a line 
and a half in length. I found many of the large ones empty. 
They have a round opening at the lower end, with a fmall 
round operculum, or lid, which now loofely covers the empty 
hu(k or (hell : the infide of thefe is lined with a fmall white 
membrane ; others were dill (hut, fome were opening, and fome 
half open, with the infeCts projecting more or lefs, and fooa 
extricating themfelves entirely.
