HOUSEHOLD INSECTS 



FIG. 130. The American spring-tail, 

 enlarged. 



The American 

 spring-tail (Lepidocyr- 

 tus americanus). 

 Marlatt describes and 

 figures a new species 

 of spring-tail (Fig. 130) 

 that is not infrequently 

 found in houses in the 

 city of Washington. 

 The individuals are 

 apparently often found 

 beneath the window 

 sills, in bathrooms, 

 and " sometimes, un- 

 der favorable condi- 

 tions, in considerable 



numbers." They are apt to occur also in conservatories 



where house plants are 



kept and where the con- 

 ditions are moist enough 



to make it agreeable for 



them. This species is 



shown in Fig. 131 after 



Marlatt. Note the 



spring-like appendage 



on the underside of the 



body, forked at the end 



and held in place by the 



catch.
