metathorax, just inside the lateral shelf-like extensions of 
these segments. Dorsally the anterior margin of these is 
sharply truncate with a slight, rounded tubercle at each 
side and a pair of more pronounced ones medially, separated 
by a slight median emargination. 
In its general habitus this species is very similar to one 
illustrated by Mjoberg from the Malay Peninsula, but his 
photograph is not sufficiently clear to indicate this definitely, 
and other accounts of what may be the same species are 
likewise lacking in details. 
The Javan Species 5 
(Plate 2) 
The four specimens of this form are all smaller than the 
preceding species as the largest one does not exceed 30 mm. 
in length. The color is darker, but this is quite probably 
due to the preservation. The thorax is fuscous above or 
darker and the abdomen piceous or nearly black, with the 
lateral projections orange yellow on the apical half. Struc- 
turally, the differences are as follows. The larger, posterior 
tubercles of the meso- and metathorax are more strongly 
transverse; the posterior margin of the metanotum bears 
four small warts, the additional ones more minute than the 
median pair and forming with them an equidistant series of 
four. The abdominal warts are present on the seventh and 
eighth segments so that there are eight instead of six pairs. 
The thorax is wider, the mesonotum measuring nearly three 
times as wide as long. The lateral abdominal projections 
are stouter, more swollen apically and quite evenly rounded 
at the apex. 
One specimen bears the label “Java, R. Thaxter”. The 
others, collected by Bryant and Palmer, are from Bantar 
Gelbary. 
A Bornean Species 
(Plate 3) 
A series of specimens from Sadong, Sarawak, Borneo 
collected by Harrison Smith are apparently the form figured 
SBurgeois, (Bull. Entom. Soc. France, 1899, p. 61) has given a 
description of this form, but not having the Sumatran one for com- 
parison does not refer to the differential characters.
