1928] Some Cuban Cicadidce , Cercopidce and Membracidce 123 
Dasyoptera variegata Metcalf and Bruner. 
The male of this species, belonging to an interesting mono- 
typic and endemic genus, was taken for the first time, and the 
external genitalia are herewith described and figured (fig. 3). It 
will be seen that their structure is a further specialisation and 
elaboration of that of Leocomia, as exemplified by L. coliina. 
The sedeagus is extraordinarily complicated, with an apical 
semi-membranous portion which I have not been able com- 
pletely to elucidate, in the one example available. 
The male genitalia of the Cercopidse afford most excellent 
taxonomic characters, especially in the sedeagus and the genital 
styles. The Xth segment is relatively simple in Leocomia and 
Dasyoptera, but in the common Philcenuslineatus (L.) — an example 
from Massachusetts— this is produced into great caudo-ventral 
processes homologous with and resembling those of the Cicadidse, 
but more flaring, whereas in cicadas they are usually parallel 
and sometimes fused, when they form the so-called “uncus” of 
American taxonomists. 
The ovipositor of the female Dasyoptera variegata is extra- 
ordinarily small and weak — even more so than that of Leocomia. 
The holotype of this species, and only other recorded spe- 
cimen, was taken in eastern Cuba, at an elevation of 6770 feet 
on Pico Turquino. Curiously enough I did not find either of my 
two examples in the main range of the Trinidad Mountains, where 
Leocomia balloui and L. coliina were both abundant. Both spe- 
cimens were swept from miscellaneous underbushes, below the 
1000 feet level, one at the Hanabanilla Palls (G. Salt) and the 
other in the wooded hills east of Soledad, on 7th April and 10th 
March, respectively. 
Lepyronia robusta Metcalf and Bruner. 
During the dry season this was the only abundant Cerco- 
pid — in fact the only adult — collected on the lowlands. 
Sweeping wayside roughage and the coarse grasses, especial- 
ly Panicum maximum Jacq., of the poireros nearly always, at 
least in February, yielded this species in great numbers. It oc-
