First flagellar joint one fifth the length of the second, which is as long as the scape; joints 3-12 gradually shorter than the preceding; terminal joint slightly longer than penultimate.

First flagellar joint one fifth the length of the second, which is as long as the scape; joints 3-12 gradually shorter than the preceding; terminal joint slightly longer than penultimate. Thorax robust;. Fig. 5.— Rhytidoponera (Rhytidoponera) araneoides froggatli Forel. Worker. scutellum prominent, convex, a little broader than long. Declivity of epino- tum longer than the base and flattened. Petiole more than twice as long as high, convex above at middle, from above, longer than broad, sides slightly convex. Genitalia not prominent. Shining, head and thorax irregularly, rugosely sculptured. Epinotum and petiole transversely strigose. First segment of gaster very densely and finely arcuately striate; striae of second segment similar, but more concentric. Mandibles longitudinally strigose. Head and body with moderately abundant fine, erect hairs. Color fuscous throughout; mandibles, antennae, and tarsi paler. Pilosity black. Wings (length mm.) infuscated. Ysabel: Fulakora. San Cristoval: Pamua, Wainoni Bay. Ugi: Pawa. Florida: Tulagi, Maliali. Malaita: Auki, near Fourafi, in the interior. Rendova. There appear to be no local varieties of this species which ranges throughout the group. Probably it is confined to the British Solo- mons, for it is very common where it occurs and would have been recorded from further east if found there. I did not find any other species of this genus, which is well developed in New Guinea. R. froggaUi lives generally in or beneath hollow logs lying on the ground, sometimes in colonies numbering several hundred but more frequently with less. It is a timid species, hustling its dark brown pupae and the larvae into the nearest shelter
