area reticulated ; triangles moderate in the anterior, short in 

 the posterior ; subnodal sector furcated midway between the 

 nodus and pterostigma ; a single row of cellules in the area 

 between the subnodal sector and the interposed sector below it. 



Type JEschna Milnei, Selys (Japan). 



The type of JE. Milnei is in my collection and is obviously 

 not a true ^Eschna, differing in its subglobose face, and espe- 

 cially in the single row of cellules between the subnodal 

 sector and the interposed sector below it. 



According to the system of Karsch (Entom. Nachr. xvii.) 

 Planceschna seems (in the absence of the male) nearest to the 

 American Epio?schna, which differs from it mainly in the 

 abdomen not being constricted near the base, in the much 

 longer triangles, and in the presence of two rows of cellules in 

 the space between the subnodal sector and that interposed.

hoc. Ndara and Athi Plains. A female example obtained 

 at each locality. The male example was procured by Emm 

 Pasha on the shores of Lake Victoria Nyanza. 



I suspect this species will prove to be identical with Cen- 

 trurus trilineatus, Pet., from Tete.
