DEGEERIAD^. 129 



Family 2. Degeeiitad.e, Lubhoch. 



Body cylindrical. Tlie appendages of the fifth 

 abdominal segment developed into a saltatory appa- 

 ratus, wliicli consists of a basal portion and two arms. 



Oechesella, Templeton. 



Segments of the abdomen unequal. Six eyes in each 

 group. Antennae 6-jointed, about as long as the body, 

 which is without scales, but covered with hairs, the 

 larger ones clubbed. Feet biunguiculate. Caudal 

 appendage long. 



The species of this genus are above the medium size, 

 abundant, and prettily mottled. They are found under 

 fallen boughs of trees, in moss, among decaying leaves, 

 and in other similar situations. JSTumerous species 

 have been described by various writers, and especially 

 by Bourlet and Nicolet, but after having examined a 

 very large number of specimens, I am satisfied that 

 the greater number are mere varieties.
