Till, —Two new Cicadas from Sarawak, with a note on 
the Bornean species of the genus, Cosmopsaltiha, 
Stal. —By J. C. Moulton, Curator of the Sarawak 
Museum. 
Having just completed and published a list of all 
known Bornean Cicadidae *, it was perhaps only natural 
to expect that more material would immediately come 
in, just to show how incomplete this list really was. 
And so it happened that two large collections of these 
Homoptcra were sent to the Museum recently—the 
results of light-house collecting at Baram Point and 
Kedurong Point, Sarawak. 
Among them were two new species, descriptions of 
which are appended. The second of this is an interest¬ 
ing form connecting two already known species of the 
difficult genus, Cosmopsaltria, Stal. I have endeavoured 
to show the relationship between the Bornean species 
of this genus, and, with the aid of a synoptical table, 
the differences by which they may be easily dis¬ 
tinguished. 
Genus, Platylomia, Stab 
wlatylomia distanti, sp. n. 
Male. Very near P. spinosa, Fab,, but differing from 
that species in the opercula which reach the posterior 
margin of the third abdominal segment, while in 
spinosa they nearly reach the fifth abdominal segment. 
The apices of the opercula in this species are evenly 
rounded inwardly and outwardly. Tegmina hyaline, 
differing from spinosa in having no infuscations at base 
of third, fifth and seventh apical areas. 
Length, excl. tegm. 51 mm.; exp. tegm. 126 mm. 
Type. Male. Kuching, Sarawak (Sar. Mus.). 
Mr. Distant kindly examined this specimen, reporting 
it as unknown to him and near P. spinosa. I have 
much pleasure in dedicating it to him. The female is 
unknown. 
* Journal of the Straits Branch, HoyaZ Asiatic Society, No. 57, pp. 323—15G 
(1911). In that paper 71 species are recorded from Borneo. But Mr. Distant 
has since informed me that the species identified as P. umhrat%, Dist. is- 
really P. spinosa, Fab., so P. umbrata, should not be included in the Bornean 
list. With the two species described in this paper, the total number now' 
therefore reaches 72,
