single pair of legs articulated to the sides, of which the last pair 

 is largest aud extended backwards. The antennae are long and 

 with numerous joints. 



Lilhohiidae. Lithobius, (Fig, 33,) called in this F'g- 33. ^ 

 country Ear-wig, is our most common genus, and is 

 found every where, under sticks and about manure 

 heaps, where they feed upon insects and earth worms, 

 and are in turn devoured by the red back salamander. 

 The head is large orbicular, antennae forty-jointed, long 

 and filiform, and there are sixteen rings in all. They 

 are fast runners. 



Scolopendridae. Scolopendra, the Centipede, has 

 twenty rings besides the two that form the head ; an- 

 tennae lt-20 jointed. A rather slender species about 

 three inches in length, is found in Maine, under dead 

 leaves. 



Geophilidae. Geophilus is greatly elongated and slender, with 

 many rings, from thirty to two hundred. A small, slender species, 

 is common under leaves, and debris of freshets, where so many 

 varieties can be found. 



Those Myriapods included in the second suborder, Chilogna/ha, 

 have a greater number of rings, each of which bears two pairs of 

 legs, and few jointed short antennae. In Polydesmus the body is 

 still flattened and the legs articulated upon the sides of the body. 

 A species occurring in considerable abundance with the myriapods 

 is about an inch long and of a pale brown color. 



Julidae. (Thousand-legs.) t/wZw-s is found commonly under sticks, 

 &c. It is long, cylindrical, hard, with numerous feet, short and 

 weak, attached to the under surface of the body nearly in the 

 middle of the abdomen. The antennae are short and filiform. 

 They crawl rather slowly, and at rest curve the body into a ring. 

 They live on vegetable substances, or eat dead earth worms or 

 snails. " In the spring the female deposits her eggs in masses of 

 sixty or seventy, in a hole excavated for the purpose under the 

 ground ; after three weeks or more the young make their appear- 

 ance, but still continue to adhere for some days by a string to the 

 shell, which has burst longitudinally without motion, and sur- 

 rounded with a proper membrane ; at that period they have no 

 legs at all ; as soon as they have got three pairs of feet, they sep- 

 arate themselves from the shell ; they have now a great resem- 

 blance to the larvae of some Coleoptera ; soon the number of rings
