Kahl: Odonata Collected on Isle of Pines. 521 



female has six postcubitals in the right front wing, but in the left 

 wing there are three supernumerary veins between the costa and the 

 median vein, one between postcubitals 2 and 3, one between post- 

 cubitals 4 and 5, and one beyond postcubital 6; this same female has 

 in both hind wings six postcubitals between the costa and the median 

 vein, and five between the latter and the principal sector. In no 

 other specimen are there more than five postcubitals in the hind wings.

Four males taken at Nueva Gerona, May 9, 1910, by J. L. Graf;

One male taken by J. L. Graf at Nueva Gerona, May 9, 1910. 



The unique male, which I refer with some doubt to this species, 

 agrees with the description given by Selys {Bull. Acad. Belg. (2), X, 

 i860, p. 461) as far as it goes, except that I do not find a trace of 

 "une grande tache vert azure pale" on the third abdominal segment. 

 The measurements given by Selys are: "Abdomen environ 25. Aile 

 inferieure 17 (large de 2j^);" Hagen has: "Length near 20 millim. 

 Alar expanse 35 millim." The specimen from the Isle of Pines has: 

 Abdomen about 27 mm.; hind wing about 16 mm.; alar expanse 

 about 35 mm. 



As the description given by Self's in 1886 {Mem. Coiir. Acad. R. 

 Belg., XXXVIII, p. 212) amending the very brief diagnosis given in 

 Sagra's Historia Natural de Cuba, VII, 1857, p. 470, is generally 

 inaccessible, I deem it advisable to give a description of this male 

 from the Isle of Pines, which is as follows: 



Inferior sector of the triangle (here long, rectangular) entirely 

 absent. Pterostigma rhomboidal with one entire cell below, alike in 

 all four wings. Subnodal sector from the vein of the nodus as in P. 

 corculum Calvert and P. amatoria Calvert {Biol. Centr. Anier., 1907, 

 PI. X, figs. 44 and 52); superior sector of the triangle in front wings 

 ending at the cross-vein descending from the nodus, but in both hind
