The major part of the selected species belong to the Longicorn Beetles, and 
as I do not accord with the arrangement of Monsieur Audinet Serville (pub- 
. lished in the French Entomological Transactions), particularly in the group- 
ing of the Lamiadæ of Leach, it may be adviseable to commence with some 
short observations on the Lamiade. 
The typical species of Lamia, according to Fabricius, was Lamia Gigas; 
that species is now detached from Lamia by Serville, under the generic name 
of Omacantha. The type of true Lamia, according to the above author, at 
present appears to be either Lamia Rubus, Fab., or some other closely allied 
species. He has, however, included under the same head three other species, 
differing considerably in form, and which may be regarded as subgenera be- 
longing to another family. The natural sections of Lamia appear to be three ; 
first, those which have the sutural apex of the elytra acuminated, each wing 
being internally more or less spiny, whilst the lateral angles are invariably 
rounded; secondly, those which have the sutural apex spiny, as well as the 
lateral angles spinose; and thirdly, those which have the elytra rounded at 
the apex, and without any spines medial or lateral. The last section requires 
still further subdivision, and most willingly do I leave that task for others. It 
is time, however, to proceed to the description of the species. 1 commence 
with true Lamia.

This magnificent species I have named in honour of Dr. Horsfield, the au- 
thor of a ene work on the metamorphosis of Indian Lepidoptera. With 
regard to size, the species ranks amongst the largest of 
the Lamiadæ which 
have yet been described as belonging to the East.
