PHILIP P. CALVERT 373 



el nombre usado por Selys en la obra de la Sagra. [This probably refers to P. 

 melella.Y'^ Si fuese igual debia tener el nombre dado por Drury. 



Gundlach quotes no localities for this species but gives a 

 description of both sexes; I have compared one male from Cuba 

 (Poey) and one female from Cuba (ex coll. Needham) with it and 

 the males agree. The description of the wings, as usual, is a 

 translation of Hagen (1861). The female before me was not 

 included in the material cited in the Biologia Centrali- Amer- 

 icana,*^^ as the male was; it has no "estrias morenas" at the base 

 of the wings, although the yellow in the subcostal space of the 

 front and hind wings and the submedian (cubital) space of the 

 hind pair is a little deeper. The general yellow of the wings 

 extends to the second postnodal for the whole width on both front 

 and hind pairs and in the costal space only as far as the stigma. 

 The extreme apex of the hind wings is brownish yellow for a width 

 of one cell. Internal triangle, front wings, two-celled, the two 

 posttriangular rows increase to three rows at the level of the 

 separation of the bridge vein (subnodal sector) from Ml (princi- 

 pal sector) and so continue almost to the wing-margin. This 

 female is of the form dotnitia (tj'pe) of the Biologia Centrali- 

 Americana;^- its wing coloration resembles more that of fig. 183 

 of "P. domitia var. 9 octoxantha Buenos Aires" of Ris than his 

 fig. 180 of "P. domitia var. domitia, Cuba."«3 



At the conclusion of his description of this species, Gundlach 

 says: "Hay una variedad con las alas cristalinas, casi amarillcntas 

 y en su borde anterior amarillas; las posteriores en la hembra 

 con una nube morena en el apice. Esta variedad habia nom- 

 brado Hagen LihcUula iris." Hagen in his original and only 

 description of iris*^^ did not cite it from Cuba.

The species described as Agrion {Enallagma) trancatttm l)y 



Gundlach on page 226 of Tomo II of his Contribucion is known to 



me from a single male only. In most respects, this male seems 



related to E. pollutum, signatum and pictum of the eastern United
