Mr. Washbrun's note in the November number (p. 320) induces me to state the Gastrophilus epilepsalis, French, is no Gastrophilus at all; in fact, not the larva of an Œstrid. The figure shows that it is a Muscid larva, very probably of Calliphora, certainly so if the figure is correct. The species cannot be identified untill more of these forms are reared. French's figure indicates that it is very close to the European C. vomitoria as figured by Pipers. There is no definite character known to identify Œstrid larvæ of some Muscidæ can be separated from the Œstridæ.
