 Just behind the antennae are 10 long, light brownish filaments, 

 five on each side. These are the filaments of the third metamere

 teriorly to a narrow base, terminating in one large, posterior spine 

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

 Labrum elongate, slightly curved, obliquely truncate and tipped 

 with an irregular tuft of hairs. Maxillae subtriangular with a 

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

 Mandibles with three prominent and two minor teeth, posterior 

 margin serrate. The conspicuous mandibular fans each consist 

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

 Air sacks of thoracic and seventh abdominal segments with many 

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

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

 Ventral brush of terminal segment composed of about 24 stout 

 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 

 consisting of stout processes with almost inconspicuous, extremely
