Hi Joyce,
It looks to me like setation of cranium extends all the way to the lateral margins of the labrum, which is diagnostic for Coelus ciliatus:


In C. globosus setation extends only to the frontoclypeal suture:

This is also well illustrated in Doyen's 1976 paper. If you have the time to look at this I'll be happy to send you a PDF.

 
Hi Hartmut
Based on what you wrote it does look like Coelus ciliatus. Can you email me the paper? I'll check higher res versions of my photos to have a better look at the setation. Thanks!

Thanks!
My photos aren't as clear as yours regarding the cranial setation but I think they are clear enough.... so am moving to Coelus ciliatus.
