These specimens are small for the species, the length, including 
the forceps, of the males is 19 and 22.2 mm. The male specimen 
from La Chorrera lacks the disto-internal tooth of the forceps.

After careful study of the literature and comparison of the 
type of insularis, and the individuals here recorded, with a large 
series of brunneipennis from the United States, we are convinced 
that insignis of Stal and insularis of Bruner are absolute syno- 
nyms of that species. Under insignis Burr has alreadj'^ placed 
his geayi, the original description of which exactly fits the male 
here recorded, except that the present specimen is smaller, with 
slightly more elongate forceps. 
The individuals here recorded are smaller than any before us 
from the L^nited States, but in that large series, far greater ex- 
tremes in size are found than between the smallest specimens and 
those here considered. It is of importance to note that in the 
males of this insect, the degree of acuteness of the four pygidial 
projections, and the degree of production of the meso-distal 
portion of this appendage, frequently shows considerable varia- 
tion. The pygidium of the male here recorded agrees fidly with 
that of some of the males from the United States; in that series, 
however, the meso-distal portion is normally distinctly more 
produced. 
The pale proximo-lateral marking of the tegmina is clearly of 
no specific or racial value. This marking is moderately distinct 
in the male here recorded, very weakly defined in the female type 
of Bruner’s synonymous insularis, from Trinidad, but absent in 
the female from Panama. The tegmina of a Costa Rican speci- 
men before us and of those from the United States are immaculate.®
