Dorsally of the end comb there are a number (seven to nine, in most cases eight) of ratherlow, smooth, chitinous pegs, in most cases arranged in two irregular parallel rows running longi-tudinally. The cavity dorsally of the end comb is moderately deep. //? ner procea of the i ndfxop oinl. Fig. LXVIII. — Ph. (Philomedes) globoaa (W. Lilljkborg). — 13.
