424 THE THYSANUIIA. 



little Spring-tails are to be met with ; some species 

 even live upon the surface of the Water, whilst others are 

 found in some localities upon the surface of the snow. 

 Another insect belonging to this order is the Le- 

 pisma saccharina, which is usually found in damp 

 places about houses, especially in the crevices of win- 

 dow-frames. Like the Podura its body is covered with 

 silvery scales, but its antennae and palpi are long, its 

 eyes are compound, and the abdomen is furnished with 

 several long bristles at the tip. The species which 

 agree with the Lepisma in their structure are less 

 numerous than the Podura ; they are found like the 

 latter in damp places, especially in woods, concealed 

 under stones, fragments of wood, and similar objects. 



With these few remarks upon those aberrant insects 

 which undergo no metamorphosis, I must take leave 

 of the reader for this time, in the hope that, if he has 

 accompanied me so far with the same desire to acquire 

 information that I have felt to impart it, our tempo- 

 rary connexion may not be found wholly profitless. 

 Now that the value of the study of Natural History 

 as a branch of mental training is beginning to impress 

 itself upon the British public, we may fairly hope 

 that Entomology, one of the most interesting depart- 

 ments of Zoology, will attract many votaries ; and if 

 this little book should contribute towards a consum- 

 mation so devoutly to be wished, I have my reward. 



THE END.
