An examination of numerous lots of this species proves it to be very 
distinct from O. aculeata (Gibbes), with which it has been confounded 
by some authors. 
The front is much narrower than in aculeata, rostrum more advanced 
and less deflexed. In aculeata a groove runs from the tip of the inner 
upper angle of the orbit along the margin of the front to the base of the 
rostrum. This groove is very slight in lherminieri. Orbital angles less 
produced and less conspicuous in lherminieri. In both species the 
basal article of the external antenna has the anterior margin more or 
less dentate. Second article, in lherminieri, with an external lobe 
which is shorter than in aculeata and directed forward rather than out- 
ward. Antero-lateral teeth sharp, while in aculeata they are obtuse. 
Appendages ‘of the male abdomen with the distal third of a light 
brown color, and gradually tapering; and arranged in the form of a 
lyre, widely spreading at the tips (Pl. xxxrv, fig. 4). In aculeata, the 
appendages are brown for about the distal half, the brown parts in con- 
a .
