with very numerous small spots of the size ol 
very small pins heads, and of nearly the same 
colour with the bark itself: each when opened 
Avas found to contain thirty or forty eggs. On 
placing this twig in the ground, in a favourable 
situation, where the sun shone freely on it, after a 
certain time prodigious swarms of extremely mi- 
nute Cocci proceeded from the eggs contained in 
the respective tubercles. Tliey were of a beautiful 
scarlet colour, and measured about the hundred 
and fourteenth part of an inch in length. Their 
general appearance was very much that of an 
Oniscus or Millepede, but with six legs, tAvo short 
bristles at the tail, and antenme of a strong ap- 
pearance, resembling a pair of forceps, being each 
curved inwards and pointed. If the male of this 
animal, which even 'in its full-grown or fixed 
state, is not more than the twentieth of an inch in 
length, bears the usual proportional difference of 
.size to the female with the rest of the genus, it 
must surely be one of the most minute of all 
winged insects*. 
* Coccus conchiformis of Gmelin’s Syst. Nat. (Reaumur t. 
5. f. 7 .) seems to be nearly allied to the former of the above- , 
described minute species.
