1. Methoca thoracica ^HNS.

M. rufo-ferruginea; capite abdominisque fasciis tribus nigris.

Female. Length 4 lines. Rufo-ferruginous; the head black, the abdomen with three black fasciae, very smooth and shining; the mandibles, clypeus, and antennae ferruginous. (Pl. I. fig. 5. [[queen]].) Hab. Celebes (Tondano).

This very beautiful insect may probably be a very large, highly coloured form of if. insularis ^HNS, described in a previous paper; but not having any intermediate in size, I have thought it advisable to describe it as a distinct species.
