. Fig. 12. Sigalion ovigerum. a. Head. c. Multi-articulate bristle with toothed shaft. b. Pinnate papilla from elytron. d. Special multi-articulate bristle. Below the neuropodial aciculum the bristles are all multi-articulate with very long and delicate blades ending like the rest in a beak-like apex. They are thinner than the supra-acicular compound bristles, and the individual articles are longer. The tops of the shafts are smooth. The ventral cirri are subulate and reach to the end of the feet.
