The fore tarsi appear to be longer than usual compared to the tibiae, and the areolet has the pedicle much longer. XANTHOPIMPLA INSULARIS, sp. nov.

Thorax smooth and shining; the middle lobe of the mesonotum with a triangular band of punctures on the base. Scutellum smooth, the keels distinct on the sides and apex. On the base of the median segment are two curved keels, which form large areae, wider than long, which are indistinctly joined to the apical transverse keel by two oblique ones ; the outer side of the latter is straight and oblique and is united to the upper outer keel, which is more distinct than the inner one. The lower half of the mesopleurae closely and distinctly punctured, the upper half has the middle depressed and less distinctly and more irregularly punctured. The metapleurae behind the spiracles are minutely punctured. The areolet is shortly appendiculated above. The abdomen has the apices of the basal five segments yellowish ; the petiole has on the basal half two curved stout keels ; the oblique apical furrow is smooth, the furrows on the apices of the 2nd, 3rd, and 4th are striated, the oblique lateral ones on them are wide and smooth. The ventral surface is pallid yellow. The ocellar region is deep black; the tibiae have no spines; the top of the scutellum is rounded and is clearly raised above and separated from the lateral keels ; the raised apex of the petiole is depressed, the apex of the depression being narrowed; there is a short wide depression on the base of the second segment in the middle; the petiole is distinctly longer than the width of its apex and is as long as the second segment; the face is distinctly longer than broad; the tarsi bear short spines.
