tooth in the neuropodial setae (fig. 36, /). Treadwell reported the 

 presence of a subapical tooth in superior neuropodial setae. These 

 setae have 7 to 10 rows of pectinae, restricted more completely to the 

 outer side than in H. grisea. Notopodia are papillar, reduced, typi- 

 cally with only an aciculum (fig. 36, g).

Unidentate neuropodial setae have been described for H. galapa- 

 gensis (Monro, 1928, p. 565). These two differ, however, in the shape 

 of the feet, the dorsal cirrophore is notably stouter in H. fusca- 

 maculata, and the notopodium is more reduced.

The type consists of a complete specimen with 46 (possibly 47) 

 setigerous segments and has 21 pairs of elytrophores, on segments 2,
