are likewise once banded with the Hghter shade. The tegmina are 

 also finely and irregularly marked with darker brown which gives 

 the insects a more or less speckled and streaked appearance. The 

 second and third abdominal segments are marked as in tolteca, 

 the spot in the present species being even more intense and the 

 lateral yellowish line by which it is margined is usually very dis- 

 tinct. Half of the specimens before us are of this general color- 

 ation. 



The female described above has the general color hair brown, 

 with the dorsal surface of the head and disk of the pronotum buff, 

 while all the other markings are in sharper contrast and the general 

 aspect is darker. The other half of the series before us agrees with 

 this specimen, with the exception of the two longer-winged males 

 referred to in the measurements given above, and a very short- 

 winged female from San Jose, Costa Rica, the color of which three 

 specimens indicates that in life they were much suffused with pale 

 green of an olive shade. 



Professor BioUey, in speaking of living individuals of this species, 

 states that ''they differ from the former species (tolteca) — above all 



by the green color of the feet and abdomen " The 



writer comments on not having seen this character of coloration 

 mentioned in descriptions of the species, probably because the 

 authors had no fresh specimens at hand. None of the specimens 

 before us have retained the slightest trace of such coloration. 



Measurements {in millimelers) of individuals treated abuvp 



The series before us indicates that the females of this species, as a rule, 

 have the tegmina and wings shorter than the males. The average length of 

 the tegmina in five males and five females from Juan Vinas, Costa Rica, is 

 as follows: males 20.4, females 17.5. Two males from the same locality, but 

 not included in the above measurements, have wings and tegmina quite as 

 long as in the more abbreviate individuals of tolteca; these two specimens 

 have a tegminal length of 22.5 and 23.5, and a wing length of 24.G and 26.8.
