communities, and always under cover. They 

 form subterraneous roads or galleries in order to 

 reach the trunks of trees, the interior of which 

 they devour. Nothing but metal or stone can 

 arrest their progress. IS 2 is a white ant in its 

 larva state, when it is designated by the name of 

 labourer. 



The mjrmeleons are well known from the 

 singular habits of the larva, described in so in- 

 teresting a manner by Reaumur. Persons who 

 have not observed these insects may form some 

 idea of their history upon inspecting the frame 

 in which they are placed ; it contains the larvae, 

 the sandy funnel which serves them as a trap 

 for other insects and particularly for ants, the 

 cocoon in which they pass to the state of nymph, 

 and the relicks of their transformation. 



The phryganece are distinguished by the fold- 

 ing of their lower wings; they proceed from 

 aquatic larvae, which reside in tubular cases 

 formed by agglutinating any materials that come 

 in their way. Several specimens are seen n os 17 

 to 22. 



The order of the neuroptera is terminated by 

 the ephemera?, which are extremely short-lived 

 insects. Their existence, considered from the 

 time their wings are developed, being of only a 

 few hours 7 duration, has been the cause of their 



3i.
