First one in thinking a sizable woodlouse?
Second pretty sure it's a wolf spider?




Found the first when I was walking home one day from the store however I couldn't get it since it kept retreating into the metal tubing.

Second one was kinda dying when I picked it up so I left him alone. 20150607_204854.jpg 20150607_204854.jpg 20150728_194104.jpg

The first spider appears to be a female Crevice Weaver (Filistatidae) in the genus Kukulcania. These lovely spiders are quite harmless and make pretty good pets. (Males are more active; females are something of a pet hole.)

The second spider does appear to be a wolf spider from what I can see - but I'd really like a good look at the eyes to confirm. See, for example, a Schizocosa species such as S. mccooki or a close relative.

The wolf spider is either Schizocosa mccooki, or Hogna antelucana, only a ventral shot can tell the difference sometimes, as both S mccooki and H antelucana can often be identical from a dorsal shot.

If the venter (belly) is solid black without a yellow spot, it's Hogna antelucana. If the belly is either pale without markings or black with a yellow spot, it's S mccooki.

As for the Kukulcania species, I cannot tell what species. There are several undescribed species of kukulcania throughout the southwest. It could be an introduced specimen of K hibernalis, but there are a few native socal species that are nearly identical save for a few differences, like thicker legs, and burrowing behavior.
