 and a series of irregular ones along the nearly truncate apex.

 with an irregular tuft of hairs. Maxillae subtriangular with a 

 somewhat curved tip. Maxillary palpus slender, tapering, curved.

 margin serrate. The conspicuous mandibular fans each consist 

 of about 16 long, spinelike processes. Eyes, deeply pigmented.

 purplish, pigmented cells. The eversible pharynx with a circular, 

 papillate tip or base bearing two lateral, stout, curved papillae.

 hairs. Apical ventral plate fuscous, finely serrate anteriorly and 

 bearing a pair of dark, stout hooks pointing anteriorly. Lateral 

 margin of segment bordered with three rows of teeth, the anterior
