 Two males, Nueva Gerona, May 9, and one male, Los Indios, 

 May 19, 1 910, collected by J. L. Graf. The superior and inferior 

 appendages are exactly as described by Scudder under "? Agrion 

 (Ishmira) cccciim Hagen" {cf. Proc. BosL Soc. Nat. Hist., X, 1866, 

 p. 189). The specimens agree exactly with the description cited above 

 from De Selys's paper in the Bulletin of the Belgian Academy.

Four males and seven females taken at Xueva Gerona, May 5 

 and II, 1910, by J. L. Graf. Three pairs were taken in coitu, two of 

 which have "orange" female? and the other pair a "black" female. 

 There are four "orange" females, all alike, with the thorax orange or 

 citron-colored, and with a mid-dorsal black stripe, and abdominal 

 segment i entirely orange or citron-colored without any trace of 

 black. There is a brown-red female, which may have originally 

 been "orange" and become discolored, marked in the same way as 

 the "orange" females and with abdominal segment I unicolorous 

 brown-red. All the males and females have on the labrum a basal, 

 transverse, black line, which is slightly extended at the middle. In 

 none is the labrum entirely yellow. The number of postcubitals, 

 with some variations, is six in the front wings and five in the hind 

 wings. One male has in both front wings seven postcubitals between 

 the costa and the median vein, but only six between the latter and 

 the principal sector. In none are there more than six postorbitals 

 between the principal sector and the median vein. One "black"
