Kramer's genus LabidojiJiorus is based on a hypopus, and the 

 name refers to the two claspers at the ventral side of the posterior 

 abdomen in the hypopus. 



Indeed , these claspers are exceedingly well fit for holding between 

 them a Mammal's hair. 



Bermacarus of Haller too has claspers, assisted by two peduncul- 

 ated muscular suckers, for the same purpose. 



No wonder that travelling nymphs , which must hing to the 

 smooth , and even often polished body of Insects , are better fit 

 for this manner of living when they are prepared with suckers. 

 To climb their pegasus their legs, especially the fore-legs are 

 provided either by enormous crooked claws to seize a hair, or 

 with pedunculated suckers, which resemble a table-spoon, or even 

 with blade-like hairs, the adhesion to the insect's body suffice to 

 fix the little creature to it.
