Psyche 
[June 
curred sometimes on Panicum barbinode Trim, also, but not in 
the lush stands of this species which grew in damp places. L. 
robusta is essentially an inhabitant of the drier pastures, whence, 
however, it tended to disappear towards the end of February, 
save in places where the Guinea grass was more closely grazed 
and consequently (?) greener. 
Clastoptera sp. 
An undetermined species of this genus occurred in some 
numbers on the imported shrub, Acalypha Wilkesiana (Mull.) 
Arg., in the Soledad Botanical Garden during February. Efforts 
to rear it to maturity, either in sleeves or in the laboratory, 
were unsuccessful owing to wholesale destruction by a small 
parasitic wasp. When this has been determined, observations 
upon it and its host and an interesting Drosophiline inquiline 
larva will be published. 
MEMBRACIDiE. 
Only one species was collected during the dry season — or 
such part of it as was spent at Soledad. Two others were taken 
in the rainy season by Dr. Salt. 
Goniolomus tricorniger Stal. 
One example only, Soledad, G. Salt, 6th June. 
Monobelus flavidus (Fairm.) 
One specimen, Soledad, 9th June, G. Salt. 
Stidocephala roiundata Stal. 
The only abundant Membracid during my stay. It oc- 
curred plentifully during February in company with the still 
more common Cercopid, Lepyronia robusta , on the rough growth 
of Panicum maximum in the dry potreros. It was swept also 
from Panicum barbinode in considerably damper situations than 
those to which the froghopper was confined. Some examples 
were taken on mixed non-gramineous weeds, among which Com- 
melina nudiflora L. bulked largely, on the edge of cane-fields and 
on guardarayas. It was beaten from adjacent undetermined 
bushes in the Botanical Garden and other Soledad localities, and
