1QO COCCUS. 



meal or powder : the legs are short and six in num- 

 ber. This insect continues to wander about the 

 plant it infests, nourishing itself by sucking the 

 juices. The male is very small, rose-coloured, 

 somewhat mealy, with semitransparent milk-white 

 wings, and four long filaments at the tail. When 

 the female is full-grown, and pregnant with 

 eggs, she ceases to feed, and remaining fixed to 

 one spot, envelops herself in a fine white fibrous 

 cotton-like substance, and lives but a very short 

 time afterwards. The young, which hatch under 

 the husk or body of the parent insect, proceeding 

 from it in great numbers, and dispersing them- 

 selves in quest of food. This species is a native of 

 the warmer parts of Africa and America, from 

 whence it has long since been introduced, among 

 exotics, into Europe. 



Coccus Hesperidum is equally common in green- 

 houses with the former: the female of this species 

 is a small, brown, oval insect, about the sixth of 

 art inch in length, of a slightly convex, smooth 

 surface, and furnished with six short legs. When 

 full grown it does not envelop itself in any floccu- 

 lent matter like the former, but remains firmly 

 fixed on the bark, under the form of an oval convex 

 shell or husk, of a polished brown colour. In this 

 state it dies, giving birth to a numerous race of 

 young, hatched from the included eggs, as in the 

 former species. The male is a very small two- 

 winged fly. This species of Coccus, like the 

 former, has been introduced into the European 

 regions from the warmer parts of the globe.
