yy Mr. W. Arnold Lewis on 
Noctuo-Bombycites, mcluding Arctia with its allies, Lithosia 
with its allies, and all the Vinee; and his third group is 
Noctuclite. His fourth group following on the Noctue- 
lite is Phalenites, being all the Geometre. After the 
Phaleiites come the Pyralites. Now this arrangement 
of Latreille’s follows closely the Linnean arrangement, 
except only in placing the Tinece between Bombyx and 
Noctua. ‘The names and order of his groups, remark, 
are Bombycites, Noctuo-Bombycites, Noctucelite, Phalenites, 
Pyralites. This shows no deviation at all from the Lin- 
nean arrangement; but it is the fact, that on examina- 
tion we find the group Noctuo-Bombycites to include the 
Tinee. In his “Considérations générales sur ordre 
naturel,” etc. (published in 1810) Latreille observes 
almost identical divisions, and in the introductory portion 
(p. 81) he states that the Lithosiw are the connecting 
link between Bombyx and Noctua, and he places the T'inece 
with the Lithosie on account of their affinity to them. 
In his volume of Cuvier’s ‘‘ Familles naturelles du Régne 
Animal,” (edition 1825) , Latreille’s first group of Nocturna 
is Bombycites. His second takes the name Pseudo- Bombyces 
(against which in a parenthesis the name ‘ Noctuo- Bom- 
bycites”’ is printed, apparently as a synonym). ‘Third 
come the T%neites ; fourth again the Noctuclites ; but fifth 
here, the TYortrices (including Pyrales); then sixth, the 
Phalenites ; seventh, Crambites. The thing chiefly notice- 
able in these arrangements of Latreille is, so far as our 
inquiry is concerned, that throughout, his order of the 
groups we are discussing, is Sphinw, Bombyx, Noctua, 
Geometra. There is no suggestion that it was proper 
to bring Geometra next to Bombyx; nor to separate the 
species of Bombyx by placing Geometra between them ; 
nor to place Geometra before Noctua; nor indeed to 
deviate at all, so far as these groups are concerned, 
from the Linnean order. We do find, however, that 
Latreille used the greatest freedom in altermg the posi- 
tion of the groups where that appeared desirable, and 
moved about at his pleasure the Pyralides, Tortrices, and 
Tinece. 
We must now turn to the group Pseudo-Bombyces, 
first used by Latreille in his last work, the ‘Régne Ani- 
mal. His Pseudo-Bombyces include Cossus and Zenzera, 
Dicranura, Platypteryx, Notodonta, Orgyia, Limacodes, 
Callimorpha, Arctia, Chelonia, or in fact by far the
