This species is discriminated by de Bormans from G. 
javana only by the coloration. From the true G. javana 
it differs in the form of the penultimate ventral segment 
of the male, but it is probable that in the synoptical table 
given by de Bormans (1900^), p. 451, he includes in G. 
javana the common species wliich we discriminate under 
the name G. ohlita. 
A comparison of the type of G. sumatrana with a good 
series of G. ohlita shows that though quite different in 
appearance, tliere are few structural characters to separate 
them. 
G. sumatrana is somewhat larger and of stouter build, 
of a uniform reddish brown, with plain feet and antennae ; * 
the pimctulation of the abdomen is finer, and the pubes¬ 
cence is very dense in the type, but is apparently worn off 
in a second specimen from Java, in the Leyden Museum.
