from The Century Dictionary and Cyclopedia
- n. A female heritor.
Sorry, no etymologies found.
Searching on google for just the heritrix part, I find lots of things, including places where I can download heritrix myself.
So, I'm thinking if I listed the agent as heritrix/1.14.3 then I'd have other bots showing up incorrectly.
But the agent match, I believe, is just the heritrix/1.14.3 part of that string above.
