Ventral View
This is a different species than your other photo, so I unlinked them. Can you get a side photo of this one?

 
Sorry, my mistake
Yes, I can get a few more shots. I will have to be more careful and not mix them up.

 
Scopa
This view is useful for showing whether or not the hind coxa has an area of dense hairs at its inner base called the scopa. The scopa is lacking in this case.

 
Scopa?
I thought that only bees had scopae. I learn something new everyday. What do these wasps use the scopa for?
Anyway, I will start posting the images of all four specimens that I gathered on 1/26/10 and perhaps I will have to frass this one to avoid repetition.

 
Scopa
Contrary to what I said the scopa is at the apex of the inner side of the hind coxa. The angle of view is critical for seeing a scopa that isn't pronounced, so it might not show up in a photo of the full underside of a specimen. I don't know that the function of the scopa has been speculated on, but I would suppose that its function might be sensory with respect to the host pupa or might assist in gripping the host pupa during oviposition.

 
Thanks for all the help
Now I can link it safely. I had four different specimens and all the others belong to a different species. I will be visiting that dead log again as soon as I get a chance. I may find a few more things yet.
I learned a few things today thanks to you.
