SOME EUROPEAN FOSSIL BEES. 315 



therefore, certainly natural. This ridge is normal for Xylocopa, 

 to which the Bombus abavus, Heer [torn, cit., p. 5), must appa- 

 rently be referred. The only doubt arises from Heer's figure, 

 which represents a similar-looking object, but with head and 

 abdomen. The Ziirich specimen may therefore not be the true 



Another Xylocopa {X. senilis, Heer) has been described from 

 (Eningen. The type appears to be at Carlsruhe, and I did not 

 see it. 



Xylocopa jurinei (Heer). 

 Bombus jurinei, Heer, torn, cit., p. 4, taf. HI. fig. 8. 



The type is a very large and stout-bodied bee, like a Bombus. 

 Head lacking, abdomen 12 mm. wide, hind legs with a coarse 

 scopa, marginal cell with a dark cloud. Only part of the 

 venation can be made out, but all that can be seen agrees with 

 Xylocopa, and not with Bombus. The second recurrent nervure 

 can be seen entering the third submarginal cell far from its end, 

 and the shape of the cell (base and extreme apex not visible) is 

 as in Xylocopa. The lower side of the cell is arched before the 

 insertion of the recurrent nervures, as in X. violacea. The 

 apical part of the second discoidal cell can also be seen, exactly 

 as in Xylocopa. There is also visible a considerable part of the 

 venation of the hind wing, showing the transverso-cubital, and 

 the ends of the marginal and cubital nervures, quite as in 

 Xylocopa. 



Anthophorites titania (Heer). 



Scutellum broad and flat ; mesothorax rather small ; meta- 

 thorax with apparently a sharp edge separating base from apical 

 truncation ; head absent ; first abdominal segment narrowed 

 basally, the abdomen broadest at middle of third segment ; 

 stigma narrow, rather well-developed; upper section of basal 

 nervure shorter than lower ; marginal cell sharply pointed, 

 rather broad basally ; rest of venation cannot be made out. 



The specimen here described is supposed to be the type, but 

 it is evidently not the one figured by Heer. The species was 

 described from two specimens from (Eningen in the Carlsruhe 

 collection; perhaps the one now at Ziirich is one of them. The 

 genus Anthophorites cannot be precisely defined, but includes 

 various fossil bees supposed to be more or less similar to 

 Anthophora. I herewith designate Heer's first species, A. mellona, 

 as the type. 



The generic position of A. titania, at least as exemplified by 

 the Ziirich specimen, remains obscure. 



Anthophorites longceva, Heer. 

 ? . Clearly a bee ; eyes large ; face narrow ; middle joints 

 of the rather stout flagellum a little longer than broad ; abdo-
