On the male genital organs of the T i p u 1 i d as with short palpi, together with the 

 explanation of Plates III. and IV. 



Tbe form of the external male genital organs of the Tipulidas with short 

 palpi is that of a forceps ; they are not different in this respect from the ma- 

 jority of the insects of the other orders. This forceps serves to seize the tip 

 of the abdomen of the female. In the cases of copulation which I have ob- 

 served in the genera Limnobia and Erioptera, the abdomen of the J 

 was seized/rom below, a little before the ovipositor, so that this organ was stretched 

 on the tergum of the <$. But, besides the external forceps, there is, between 

 its two halves, a second internal forceps-like apparatus. After having secured the 

 female in the described manner, the male, with this second apparatus, seizes 

 the orifice of the inner genital organs of the female and adjusts thereon for 

 copulation. This second forceps seems to vary in structure in different species.
