of a large size compared with the insect ; hence, it is 

 probable that a single female does not deposit above 

 eight or ten eggs. They are affixed to the stem at 

 one end, by means of a black viscid secretion, which 

 dyes the surrounding part of the stem for a short 

 distance. We have often observed two eggs placed to- 

 gether, one by being attached at the extremity of the 

 other. Their colour is dirty slate. In a short time 

 the larvae are produced. In this state, they are quite 

 the reverse of their parents, and, instead of exhibit- 

 ing a variety of colours and elegant markings, thev 

 are of a disgusting form and a dirty slaty green colour, 

 almost black ; and, when disturbed, they emit a con- 

 siderable quantity of thick black fluid. The body is, 

 as usual, composed of 13 segments, the first of which, 

 or the head, is black, and supplied with strong four- 

 toothed jaws, and short antennae ; the next segment, 

 or the prothorax, is marked with two shining black 

 spots, of a leathery texture, and is furnished on the 

 under side with two short, articulated, black legs, as 

 is also each of the two following segments ; the re- 

 maining segments are gradually thickened. The 

 general consistence of the body is fleshy, the external 

 integument being thin and membraneous; the seg- 

 ments of the abdominal part of the body are fur- 

 nished with fleshy tubercles, which are employed as 

 legs. The body is also armed at its extremity with a 

 similar pair of these fleshy proleg-like tubercles. It
