HEMIMERUS 2 19 



apparently about six at a time, the larger one being of course 

 the nearest to the orifice. Dr. Hansen thinks the young- 

 specimens are connected with the walls of the maternal passages 

 by means of a process from the neck of each. But the details of 

 this and other points are insufficiently ascertained ; it is, indeed, 

 difficult to understand how, with a process of the kind of which 

 a fragment is shown in Fig. 116, b, the Insect could fix itself 

 after a detachment for change of position. The young is said 

 to be very like the adult, but with a simpler structure of the 

 antennae and abdomen. On the whole, it appears probable that 

 Hemimerus is, as stated by Dr. Hansen, a special family of 

 Orthoptera allied to Forficulidae ; further information both as to 

 structure and development are, however, required, as the material 

 at the disposition of the Swedish entomologist was very small.
