ANIMAL BEHAVIOR, WITH EXAMPLES

in his reply he said; "The hymenopterous parasite bred by 

 you from a lepidopterous larva came a couple of days ago and 

 I have examined it with much interest. It falls into the tribe, 

 Campoplegini, and into Foster's genus, Anephares. No species 

 is yet known in the North American fauna and you will he safe 

 in describing it as new. Of course it might be described under 

 the genus Limneria (now Limnerium) somewhere, but I know 

 most of the species described in this genus in our fauna, and all 

 are quite different from your specimen." 



This new species, which I will now call by its new scientific 

 name, Anephares rufipes, or the red-legged Anephares, is three- 

 eighths of an inch in length. Its body is black; its legs and 

 ovipositor being reddish brown. The caterpillar from which the 

 grub emerged showed signs of life for several hours after the 

 parasite had left its body, and gradually shrank into a hairy

original size, before life was 



entirely extinct. I have

The Ant-Lion 



OW often we are surprised at the 

 fertility of animal life in supposedly 

 uninhabited places! Who but the 

 naturalist would look to a small area 

 of pure sand, supporting scant vegetation, as an 

 enticing habitat for certain insects! To such a 

 spot, of only about five yards in extent, on the top 

 of a bluff bordering Lake Michigan, I have often 

 made visits to view the performances of the ant- 

 lions. When the sun shone brightly for a day or 

 two during the heat of summer this place was always an
