I can by no means agree with Dr. Horsfield, in considering the insect which he 
has figured under the name of Pithecops Hylax as identical with the Fabrician insect, as 
that which is here figured is marked more agreeably with the original description of the 
species, short as it is. Had Fabricius been describing Dr. Horsfield’s insect, he would 
have said “ strigis duabus submarginalibus punctorum nigrorum,” instead of “ nigro- 
punctatis,” which implies a general scattering of dots over the wings ; moreover Dr. 
Horsfield’s insect exhibits no trace of the “ arcubus fuscis,” described by Fabricius.
