The status of Professor French's Gastrophilus epilepsalis, described in the September number of this journal, has interested me especially, as I am preparing a new catalogue of North American Diptera.

I am convinced that it was decidedly premature to assign a specific name to this larva. In the first place, it was very small and immature, and the earlier larval forms of Oestridæ are much less known than the later, so that we do not possess the data that would enable us to separate this species, for instance, from G. nasalis.
