On the whole, however, as we Lave seen, it is not so generalized a group as the Micropterygid;e, a group common to Europe and North America.

Its relations to the Cossida-, including the Zeiizerina, remain still to be elaborated; they are-ratber close, yet the Tortricoid affinities are very apparent, and need further examiuation. Thepupa of Zcuzcra ?pyrina (fig. 40) is of the same character as in Prionoxystus, but the maxillaryl)alpi are larger, the lateral palpi more reduced, while the cell-breaker is very long, being muchmore developed.
