coccus. 1Q7 



with very numerous small spots of the size of 

 very small pins heads, and of nearly the same 

 colour with the bark itself: each, when opened 

 was 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. They 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, two short 

 bristles at the tail, and antennae 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.
