BORNEAN CICADIDAE. 
Distant in his Monograph of the Oriental Cicadidae 
(p. 49) says of this species and the next: “C. lawta and 
C. latilinea are very closely allied, and they are evidently 
local races of one species.” 
In as much as they have both been taken in one loca- 
lity in Sarawak, and since they present well-mar’sed and 
constant differences, I prefer to treat them as separate 
species. 
The Sarawak fone of C. duarum (C. lauta) vary in 
the heaviness of the mesonotal markings, the ground- 
colour of the pronotum and mesonotum, which ranges 
from olive-green and ochreous brown to a bleached olive, 
and the black marginal suffusions in the opercula vary in 
breadth and definition.

This species has been taken at Baram, Kedurong, Bintulu, 
and near Kuching (Sarawak Mus.); at Bau in August 
(coll. C. J. Brocks). 
Previously it has only been recorded from Penang. 
This species is easily distinguishable from the preced- 
ing by the presence in the tegmina of fuscous spots at 
the base of the fifth and seventh apical areas, and a row 
of hind-marginal fuscous spots at the end of the trans- 
verse veins. The fuscous border on the opercula is al- 
ways well-defined and varies but little in breadth. 
The following variations are noticeable in a long series 
~ in the Sarawak Museum :— 
(a) The absence or presence of a black oblique line on 
each side of the pronotum.
