as having the costal membrane broad with many cross- 
veins. Distant 1906n : 355 in the original description makes 
no mention of costal cross-veins, neither does Myers. The 
specimens we consider spinolse have no costal cross-veins. 
The structural characters are indicated by the figures. This 
insect was listed by Pedro Valdes as Dictyophora spinolse 
based on the specimen in the Gundlach Museum (No. 102) 
which is probably also the origin of the name employed by 
Osborn 1926c : 354. 
The color of fresh specimens is bright olive green with 
the eyes orange brown, faded specimens are more or less 
testaceous. 
Male genitalia, seventh segment elongate, the median 
notch strongly elevated, forming a triangular tooth. Eighth 
segment short, almost concealed by the seventh segment. 
The median length of the ninth segment about twice as 
long as the median length of the seventh segment, broadly 
emarginate posteriorly. Genital plates elongate, nearly 
three times as long as the median length of the ninth seg- 
ment; contiguous ventrally; dorsal margin with a distinct 
triangular tooth, basally. Tenth segment spatulate; the 
apex notched. Anal spine elongate, extending about one- 
third of its length beyond the apex of the tenth segment. 
Specimens are at hand from Camaguey, July 15, J. A.,

Ladella acimae n. sp. 
This species differs principally from Ladella pallida 
Walk in the short transverse vertex. The vertex in acunse 
is twice as broad as its median length whereas in pallida 
it is not as broad as its medan length. 
Vertex, twice as broad as its median length; the anterior 
and lateral margins distinctly carinate, the anterior mar- 
gin broadly rounded, the lateral margins parallel, the pos- 
terior margin nearly parallel to the anterior margin; me- 
dian carina not strongly elevated. Frons, elongate, about
