marked with red or orange, and with the hind legs fringed with long hairs, 
orange on the outer surface and black on the inner. When full grown the 
larvae leave the stems and go into the soil to cocoon and pupate. The genus

Sesia (Fig. 563) contains over half (fifty-seven) of the species in this family; 
they are found in all parts of the country. 
The family Notodontidae, comprising the puss-moths, handmaid-moths, 
and prominents, is represented in

Notodontids. Sometimes there may b 
other shade-tree an animated bunch 
this country by about ninety-five 
species, all of medium size, i.e., with 
a wing expanse of from i\ to 2 
inches, and but few of such marked 
patterns as to be particularly con¬ 
spicuous or attractive to collectors. 
The name “ prominents,” sometimes 
applied collectively to the moths of 
this family, is based on the occur¬ 
rence in some of them of an angu- 
lated or tooth-like projection near 
the middle of the hinder margin of 
the fore wings. Probably the most 
familiar species in this family are 
the Datanas, or handmaid-moths; 
certainly their larvae are more often 
seen and are better known, under 
the names of yellow-necked apple- 
tree caterpillars and walnut cater¬ 
pillars, than the larvae of any other 
seen on the trunk of an apple- or 
r mass of hundreds of caterpillars,
