 gular prolongation. The following second to sixth abdominal segments 

 with three dorsal areas, prescutum, scutum and scutellum, and, with the 

 spiracle-bearing alar area dorsally split into two prolongations, the 

 anterior of which being adjacent to prescutum. Seventh to ninth abdom- 

 inal segments with more or less indistinctly marked or completely fused 

 dorsal areas. Tenth abdominal segment about twice as long as head 

 from tip of labrum to occipital foramen, obtusely conical, well separated 

 from ninth segment which is somewhat larger than the tenth ; below 

 with numerous, well developed straight setae, promiscuously scattered, 

 medianly not arranged in special rows. Anal slit transverse, terminal ; 

 upper anal lips not sharply defined ; lower anal lips posteriorly limited
