It is evident that the variation in the present species and its races 

 is further emphasized by the measurements given above. It is true 

 that the specimens from Vera Cruz, Mexico, and Castillo, Nicaragua, 

 have in the female sex ovipositors very much shorter than are found 

 in any of the other specimens before us. These specimens are also 

 different in being the only ones at hand having the lower portion of 

 the head much paler than the upper portion, and the maxillary palpi 

 pale with only the distal portion of the terminal segment very dark. 

 In other respects these specimens agree almost perfectly with typical 

 ciibensis, and after a careful consideration of the variation in the 

 species, these differences do not warrant considering this material 

 worthy of racial distinction. 



Color Notes. — -The specimens here described agree well with other 

 macropterous specimens of the species before us in the coloration- 

 here given. General color very dark Vandyke brown, glossj% shading 

 to burnt umber on limbs and tegmina. Head and pronotum very 

 dark Vandyke brown, immaculate, shining; eyes equally dark. 

 Maxillary palpi^^ Vandyke brown, the terminal segment very dark. 

 That portion of the head which fits under the pronotum may be 

 seen to be a very little paler than the other parts of the head when 

 examined closely. Tegmina translucent, shading from Vandyke 

 brown in the proximal portion to burnt umber on the greater part 

 of both dorsal and lateral fields; intermediate channel very faintly 

 defined in burnt umber. Dorsal surface of abdomen shining black. 

 Exposed portion of wings burnt umber, concealed portion very white 

 when folded. Limbs and ventral surface of insect immaculate, 

 limbs above prouts brown, ventral surface pale^ but varying con- 

 siderably in depth of coloration. 



We have but one large series of brachypterous specimens of cubensis 

 before us, these from Homestead, Fla.,the majority of which specimens 

 are not of as solid coloration and are of somewhat lighter shade than 

 the specimens described above. In these the penultimate segment 

 of the maxillary palpi is mummy brown, the other segments of the 

 very dark general coloration. Pronotum a little maculate with 

 mummy brown, tegmina marked with the same color, the intermediate 

 channel quite distinctly defined in the lighter color in several speci- 

 mens. Limbs prouts brown, maculate to a slight degree with darker 

 shades. 



52 In some very dark specimens before us, the penultimate segment of the 

 maxillary palpi is nearly white, while the other segments are very dark; in a few 

 of the other specimens only the distal portion of the terminal segment is very dark.
