This Javan species is well characterised by the form of 
the penultimate ventral segment of the male, which is 
broad and rounded but depressed in the middle, with a 
well-marked ridge on each side. 
The abdomen is also more strongly and more abruptly 
dilated towards the apex than in most other species, thus 
resembling G. electa, and the forceps are asymetrical, the 
right branch being bowed inside the left. 
It is so far only known from the unique male in my 
collection, taken by Friihstorfer at Pengalengan, in 
Western Java, at an elevation of 4000 feet.

This species is probably represented in many collections 
under the name of G. java.na, together with G. oblita. 
Several years ago Dr. Borelli called my attention to the 
fact that apparently two species were confused in col¬ 
lections under this name, and inquired my opinion. It 
was not, however, until the opportunity of examining de 
Bormans’ type of G. javana presented itself, that it 
became obvious that neither of these two was the real G. 
javana, and consequently new names became necessary 
for them both. 
G. electa, which occurs in Ceylon and in Java (c.m.) is 
one of the smallest of the genus, and has the most strongly 
dilated abdomen, in correlation with which we find the
