In his figure of the head, the frontal carinae are broadly curved at sides, the thorax is distinctly broader than the head; the mesonotum is not distinctly separated from the epinotum and is more than twice as broad as long; in kaipi the frontal cai'inae are narrowly curved, the thorax is barely broader than the head and the mesonotum is less than twice as broad as long. The epinotal and petiolar spines of kaipi, as well as the humeral spines are very much longer than in scutulatus. Poli/rhachis aurita Emery, also closely related, has the thorax proportionally very much broader, and is diff"erently sculptured with the epinotal declivity and posterior surface of petiole striate, instead of smooth as in kaipi. 117. POLYRHACHIS (MyRMATOPA) ULYSSES Forcl. Rev. Suisse zool., 1910, 18, p. 91, ^ . Female. Length 10 mm. Ocelli very small. Mesonotum convexly declivous at anterior third; posterior two thirds slightly convex and narrowly and very feebly margined at sides. Scutellum transversely oval. Prescutellum with weakly margined. Fig. 53.— Polyrhachis (Myrmatopa) ulysses ForeL Petiole from front. anterior border. Base of epinotum thinly margined at sides, the margins lacking the anterior angulate structure found in the worker, spines more slender than in the worker. Petiole similar to that of worker. Wings (length mm.) clear, veins and pterostigma Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations ma
