COLLECTING AND PRESERVING INSECTS. 



Neuroptera (Fig. 23, Forceps tail, Panorpa; Fig. 24, Man- 

 tispa) have the mouth parts free again, the wings large and 



net-veined, the hind pair being often 

 larger than the primaries. Their 

 bodies are more elongated than 

 those of other insects. The meta- 

 morphosis is incomplete, the larvae 

 and pupae closely resemble the im- 

 agines, and are both active, and 

 with few exceptions they are all 

 aquatic. The different species pre- 

 Mantispa. seu t strong analogies to all of the 



other suborders. The wingless, lower genera present more 

 analogies than other insects to the Myriopods. 



The order of Arachnida is divided into three suborders : — 



Araneina, or spiders, which pass through no metamorphosis. 



Pedipalpi, or harvest-men (Phalanghim) and scorpions, 

 which undergo no metamorphosis, and all agree in having the 

 maxillary palpi enlarged and ending in a forceps, with the 

 abdomen distinct!}' jointed, and the 



Acarina, or mites, the young of which are usually born with 

 but three pairs of feet, and in which the bod^v is oval. 



The order of Myriopoda is divided into the Chilopoda, of 

 which the centipede is a type. In these each ring bears but 

 a single pair of feet, and the body is flattened ; while in the 

 second division, the 



Chilognatha, the body is cylindrical, and each segment ap- 

 pears to bear two pairs of legs. Of this group the thousand 

 legs {Jidus) is a type. 



SPECIAL DIRECTIONS FOU COLLECTING INSECTS. 



We now proceed to give more special directions for collecting 

 and preserving insects of the different groups.
