MYRIAPODS. 17 



CASE species, too minute and slender to allow anything to be done 

 against it by direct manipulation. When viewed under a magnify- 

 ing-glass it will be seen to be a very pretty little animal, like a 

 pale thread, about the thickness of a pin, with a double row of 

 bright crimson spots on it, and when put in spirits it stains the 

 liquid of a purple hue, to which it itself turns after death. It has 

 no eyes, which has led to its being regarded as belonging to 

 another genus. This is the species which most frequently forces 

 itself upon the attention of horticulturists, and Hlies seem espe- 

 cially the object of its attacks. 



The specimens of lily scales (No. 19) were presented to the 

 collection by Mr. George F. Wilson, F.R.S., from plants which 

 were entirely disintegrated by them, and a correspondent of 

 one of our horticultural periodicals {The Garden) not long ago 

 stated that on turning out some pots of Eucharis amazonica and 

 Vallota, which were not thriving, he found, besides acari, a 

 quantity of this species of snake milliped busy about the roots. 

 Further investigation showed that the roots of some of the sickly 

 plants had been perforated by these msects, which had also eaten 

 their way into the body of the bulbs themselves. Curtis, from his 

 own knowledge, specifies the roots of the scarlet runner, the roots 

 of the cabbage tribe generally, and the roots of young wheat, as 

 having been attacked, and Mr. Wilson Saunders notes that he 

 had observed that the young roots of heart's-ease were injured by 

 this species.
