Allied to E. saravacensis, Shelf. Testaceous ; the ground-colour 
however obscured by a dense castaneous maculation and vermicula- 
tion. Pronotum not covering vertex of head, not punctate, posterior 
margin angulate, 95 mm. x 13mm, _ Large ocelliform spots on 
the distal halves of the tegmina ; mediastinal vein stout with three 
short branches and one slender ramose branch, costals few but 
highly ramose ; surface of tegmina not punctate. Wings with mar- 
ginal field semi-coriaceous and suffused with castaneous, apex not, 
sinuate or angulate. Sub-genital lamina produced, trigonal. Front 
femora beneath with eight spines on anterior margin, two on pos- 
terior margin, no genicular spine ; formula of apical spines 7, 4, 4.

a congeries of species that it is not easy to discriminate ; 
the differences in coloration are slight, and it is almost 
impossible to express them in writing. The species are 
small, averaging 25 mm. in total length; they are amber- 
coloured or testaceous, the ground-colour however being 
obscured by densely placed and minute castaneous or 
fuscous macule, and vermiculatious, so that the insects 
appear to be of some shade of castaneous. The pronotum 
does not cover the vertex of the head, its posterior margin 
is obtusely angled and produced, its surface is quite 
smooth. The posterior legs are long and slender, the meta- 
tarsus particularly so, and the pulvilli are margined with 
spines. The veins of the tegmina are strongly marked, 
and between them at the base only of the tegmen appear 
series of shallow ill-marked punctures. YZ. pwncticollis, 
WIk., from Borneo can be distinguished by two converging 
impressions on the front part of the pronotum; JZ. /zvicol- 
lis, Sss., from Java is possibly synonymous; £. guadrinotata, 
WI1k., from Borneo is smaller (20 mm. total length), has 
four fuscous maculz on the pronotum, and the supra-anal 
lamina is notched deeply, not merely cleft; Z. plena, Wlk., 
from Celebes and New Guinea has no impressions on the 
pronotum and is larger than quadrinotata, the form fervida
