THE CANADIAN ENTOMOLOGIST 23 



figure of Formicium requires revision, and I give a new one, showing what 

 can actually be seen. The dotted lines followed by ? are probably no more 

 than folds or creases. Presumably there was at least one transversocubital 

 nervure, but it could not be seen. 



Comparing these wings with the modern Siricidae, they are so close that it 

 is not certain that a distinct family is indicated. Probably a subfamily, Pseudo- 

 siricinae, contrasting with the living Siricinee, would suffice for the fossils. 

 Formicium appears to differ strikingly from Megapterites in the first submarginal 

 cell, which is entirely separated from the first discoidal, and looks as if it be- 

 longed to the marginal series. In Megapterites the first submarginal is broadly 

 sessile on the first discoidal, as in most Hymenoptera. The arrangement in 

 Xeris caudatiis Cress, is not very different from that of Megapterites, but Sirex 

 gigas L. has the first submarginal separated from the discoidal, much as in 

 Formicium. The marginal cell in Sirex may be distinctly closed, as in 

 Megapterites, or may be open by the fading away of the apical region. A speci- 

 men of Sirex xanthiis Cam. has the first submarginal touching the discoidal 

 on both sides, and on one side the submarginal has a cross-vein, purely an 

 aberration. But the most remarkable specimen is a Sirex californicus Norton, 

 the two sides of which are very different, one having the first submarginal 

 broadly sessile on the discoidal. the other having these cells separate. There 

 are other abnormalities in the wings of this insect, but they do not concern 

 our present problem.
