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 Xotodontida;, comprising the pu.ss-moths, handmaid-moths, 



and prominents, is represented in 

 =^rr r? 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- 

 latcd 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;
