SCHOOL ENTOMOLOGY 



The family Lithosiidce will 

 probably be encountered in 

 the form of one small spe- 

 cies, which is colored a deli- 

 cate, though somewhat faded, 

 pinkish red, and striped with 

 black. There is no really 

 appropriate common name 

 for this insect. 



54. Geometridae. This 

 family is well known to all. 

 The larvae, variously called 

 "span-worms," " inch- 



worms 



and 



measuring- 

 worms," were among the 

 earliest of our insect friends. 

 Their presence upon our 

 clothing was welcomed as 

 presaging new clothes and 

 we were not even squeamish 

 about letting them crawl on 

 our fingers. They lack the 

 three pairs of pro-legs in 

 the middle of the body and 

 so must travel by looping 

 themselves along, hence, 

 another common name the 

 "loopers." They are the most 

 glender of the caterpillars, 

 are frequently green, but
