I've just kept western skinks short term, but I imagine their care would be similar. They need a bit more humidity than aspen can provide. I recommend a substrate like repti-bark. Make sure that there are hiding places where the substrate stays moist (I like to mix in some damp bed-a-beast and lay a bark slab over it and lift it and spray regularly) or they will have shedding problems. UV light from a good bulb like Zoomed's reptisuns is also beneficial. I also like to use a calcium supplement conaining vitamin D3 (Rep-cal) to help ward off metabolic bone disease. With any calcium supplement, read the ingrediants and make sure it doesn't contain phospherus (these are for herbivores) and I've had problems myself and have heard from others who have had problems with MBD in insectivores when using phospherus containing calcium supplements (even those marketed for insectivores). Crickets also make the best staple, mealworms tend to be too fatty and you can run into problems with obesity. Gutload crickets with a nutritious food like fish flakes or crushed high quality dog or cat food with fresh fruits and veggies (carrots and oranges are my favorites) for moisture for at least 4 hours before offering them to your skink (I know that you said that you're familiar with the feeding needs so please forgive me if you've heard this already, but some snake keepers assume that store bought insects are "good to go" as soon as you get them).
Go easy on the other posters here, most have never kept Eumeces so it's not because they don't care; they just have no experience with this genus and, therefore, have no advice to give. The blue tongue skink posts get answers because there are a lot more active posters who have blue tongue experience, not because of some elitest mentality.
