Let us now, after having reviewed the gen- 
eral distribution of Dizerizal Lepidoptera. exam- 
ine into the dispersion of a few genera and spe- 
cies of the Wocturnal Lepidoptera,commencing 
with the great family Sfzmg7do2. and taking, 
forexample our familiar Derlephild daucus, 
which has a very wide distribution, being spread 
over portions of the West Indies, North America 
and Europe; while the beautiful Chverocampa 
Nerei isconfined to the sub-tropical regions of 
the O'd World, being found in Natal, Sierre Le- 
one, Italy, Greece and Ceylon. Sphinx guingue 
macu ata and sat lita is confined to the United 
States and parts of Canada. The beauuful 
Smerinthus humolinit is contned to Natal, 
The 
Mee 
and Coegrisosa austravasiae to Australia. 
beautiful genera Cran dae of which 
hive 
and in the West Indies, 
representatives in the Oriental regions 
Take the sub-family 
Per tcopidae, which are exclus vely West Indian 
forms, On glancing over a case or two and 
placing them by side a case of Helicontis we 
notice a striking similarity, so it is the same be- 
tween the Uranzas and /apelros, 
However it is not the subject of this paper to 
discuss the imitative characteristic as displayed 
in the Insect World ,but at some future time to 
to pay some attention to this delightful field 
of study, 
As has before been stated the original home 
of the above group is the West Indies, that 
they are confined thereto with the exceptions 
of Bizarda optima which is found scattered in 
parts of the Malayan Archipelago; Zuschema 
flavata in Timor; Zusch-ma bellona is dispers- 
ed through-out a greater portion of India, while 
Proesos mariana is found in Australia, and 
Evasmia pulchells isa native of North India. 
Agein we find a number of beautiful species 
of this group to be spread over portions of South 
America, such as Aucyane meluxantha and 
E, glauca, of Brazil. 
We pass now to the Aombycidoe proper, of 
of which we have representattves in most every 
15> 
country of the globe. The number of North 
American species 1s very great, hence we will 
only mention a few. Take the Se/urniidae, 
such as Sama cecropia, spreading over a great 
portion of the United States and parts of Can- 
ada; while Sama cal/eta is confined to portions 
of Mexico, Telea polyphemus is foui 
North and South America, tics t 
is dispersed over the United States and paiis 
of Canada. The beautiful 77vopfeunoe are con- 
fined to North India. Vhe genus /yferchirea 
is a very large one, having a very wide distri- 
bution over the Western Hemisphere, being: 
well represented in other countries. 
while 
Again let us pass on and take as an examp- 
le of very wide distribution Heliothys Armigera 
of the genus Ay/entes being found in Europe, 
Gibralter, Navigators island, Rio de Janeiro, 
Nat. 1, Congo, Venezuela, parts of the United 
States, West Indies, India, Australia and Cey- 
lon, while Ludryus grata and Euglyphia hie- 
r glyphica are confmed to parts of North 
America, 
The great and interesting family Mocturide 
are found to be dispersed over the earths surface 
but are more abun.laatiy found upon the Ame- 
rican continent. The group 7rigonodes are 
contined to parts of India, China, Africa, Aus- 
tralia and Java. Sois the family Ca¢aco/Za con- 
fined to the Nor h American continent, while 
the family Geomet;ide is spread over the whole 
northern hemisphere. 
The last group that can be mentioned in a 
paper of this nature is the “7 rteZzas which is 
mostly confined to Brazil and greatly resembles 
to a certain degree our Papi/ios, 
Such though briefly , I have attempted a re- 
view of the distribution of some of the more im- 
portant families, gen-ra and species of butter- 
flies and moths as they are dispersed over the 
earth’s suiface, aided by the prevailing winds. 
The distribution of snecies constantly takes 
place overlapping one another, until we have a 
commingling of forms representing as many cli- 
mates or zones. 
In one given territory of a subtropical or 
south temperite nature such as Japan, we 
have an overlapping of Asiatic, Australian, Af- 
rican, European and North American forms all
