There being only a specimen of the female in the collection, the 
claim to specific rank is perhaps uncertain; but the form of the 
clypeus, labrum, pronotal lobes, and subgenital lamina dis- 
tinguish it from all the others. The ova removed from it are 
oblong-cylindrical, pale testaceous, measure 4°5--5 mm. in length 
and 1:25 mm. in transverse diameter, and under a Coddington 
lens, exhibit close, regular, and oblique lines in transverse sets.
