The Ants of the Baltic Amber. 141 



to forage. We should expect, therefore, to find them very rarely or 

 not at all in the inclusions. 



Mayb, was of the opinion that C. mengei is very nearly allied to 

 the recent C. maculatus sylvaticus Olivier of Southern Europe, but 

 the resemblance between these two forms does not strike me as being 

 very close. The amber species does not have the habitus of the 

 maculatus group in the shape of the head, which, in the largest 

 workers I have seen, is subrectangular with feebly rounded sides and 

 posterior border, and the clypeus is very feebly carinate and has 

 a very short lobe with rounded corners. It also lacks the rows of 

 graduated, oblique bristles on the flexor surfaces of the middle and 

 hind tibiae, a negative character which would, according to the present 

 arrangement of the subspecies of C. maculatus, remove it from the 

 sylvaticus group and ally it more closely with the subspecies atlantis 

 FoREL, aim FoREL and turkestanicus Emery. But it can hardly be 

 said to resemble these forms at all closely in other respects, and 

 should, in my opinion, be regarded as a much more primitive and 

 generalized species than maculatus sens. lat.
