Sub-family 5. OANTHOCAMPTINJI, nov. sub-fam. 



The characters which chiefly distinguish the species 

 belonging to this sub-family are as follow : The inner 

 branch of the second antenna is usually 1-jointed, and 

 always very small ; the mandible-palp consists (usually) 

 of one branch only; the second foot-jaw forms a 

 grasping hand; the inner branch of the first foot is 

 elongated (usually 3-jointed), and more or less adapted 

 for prehension, sometimes, though not always, power- 

 fully clawed, while the fourth pair nearly always, and 

 sometimes also the second and third, have the number 

 of joints in the inner branch reduced to two, or even 

 one. Ovisacs one or two. 



The genera which come under this sub-family are 

 Canthocamptus, Mesochra, Attheyella, Tetragoniceps, 

 Diosaccus, Laophonte, Normanella, Cletodes, and Enhy-
