6. Two rows for one or two cells in all wings of two females 
celaeno ; in three wings only of one male and two females 
celaeno ; in one front wing only of one female inacuta , three 
males and one female celaeno ; in both hind wings only of one 
female imitans ; in one hind wing only of one male imitans , 
one female liemichlora , three males and three females celaeno, 
6.107 %. 
7. On the front wings, slightly nearer than the second antenodal 
in the majority of celaeno , liemichlora , marmorata males, pseu- 
dimitans males, in some inacuta , imitans , tenuis, and inequiun¬ 
guis ; in others of the species implied by this statement, in 
pleurosticta and tessellata , at the second antenodal or slightly 
beyond. On the hind wings at or slightly beyond the second 
antenodal. 
8. Normally tenuis and marmorata have two, the other species 
one; two exist on both hind wings of one male inequiunguis , 
one hind wing of one female pseudwnitans, .57^ %. 
9. Crossed in one front wing of one female pseudimitans, .382 %. 
12. Three cells then two rows, or three rows may be inserted in 
the midst of the two rows in celaeno as detailed post under that 
species. One row in the middle of the field in marmorata 
males. 
13.. One in tenuis , marmorata, imitans, inequiunguis males, pleu¬ 
rosticta, liemichlora males, pumila females, some males of 
pseudimitans and of celaeno ; two in the others, as implied, or 
not mentioned. 
The variation in the variable characters 6, 8, and 9 is for the 
males 1.579 %, for the females 5^ %, the numbers of individ¬ 
uals being respectively 76 and 55. 
The accompanying diagram will perhaps indicate the relationship 
of these five genera in a more graphic manner than the table on pages 
303-304. In its construction much weight has been laid upon the 
results furnished by the variations from the generic characters. For 
variations from generic characters may represent generic characters 
of ancestors. The beginning, Dytliemis, and the end, Macrothemis, 
of this series of live genera seem to be indicated by the degree of 
modification of the legs. This much granted, the variations in gen-
