12 BUTTERFLIES. 
Bell-moths (Tortricid#); (Chonchilidz); (Grapholithidz); 
and Tineids (Tineidz), to which belong numerous families 
of such insects as leaf-miners, cloth and fur-moths, grain- 
moths, etc. . 
As this bulletin is mainly written for the use of the hor- 
ticulturist, it is impossible to make it at the same time a

well known or destructive species have been selected for 
this purpose. 
BUTTERFLIES. 
(Rhopalocera). 
FAMILY NYMPHALIDZ OR FOUR-FOOTED BUTTERFLIES. 
These butterflies are also called ‘‘brush-footed;”’ they 
differ from all others in our fauna in having the fore-legs 
very greatly reduced in size in both sexes. The legs are so 
much dwarfed that they can not even be used for walking, 
but are folded against the breast like a tippet. 
THE MILKWEED BUTTERFLY OR MONARCH. 
(Danais archippus Fab.). 
This well known large butterfly, with reddish-brown 
wings marked with black veins and white spots, is very 
abundant in late summer and fall. It sometimes gathers 
in large armies about our wind-breaks, just previous to 
migrating south, where it spends the winter. The cater- 
pillars, which grow to about aninch and a half in length,
