above the origin of the sector radii, is connected with the trunk by 

 jnly two cross-veins; so that only two closed cells are developed — as 

 in many species of the genus Eaphidia. In recent species of Ino- 

 jellia there is always one more cross-vein here, and, therefore, one 

 more cell also present. In general, these two main branches of the 

 media divide into two secondlary branches only, each of which ter- 

 minates in a fork. Behind these two cells, which lie between the two 

 main branches of the media, that is, behind the first one, and 

 posterior to the second main branch, there is still another cell; but 

 I am unable to state with certainty whether this lies between the 

 second and a third branch of the media, or between the latter and the 

 cubitus. The former case is characteristic of Inocellia; the latter of 

 Baphidia.

Since there is nothing to be seen of the head, it cannot be deter- 

 mined whether or not ocelli were present. Nevertheless, if I were to
