sides, frontal portion before insertion of antennae conically produced; 

 dorsal head-hairs single but numerously branched, in a line between an- 

 tennae, a smaller hair at base of antennae ; two long approximate setae 

 on front margin. Antennae subcylindrical, slightly tapered, spined on 

 one side ; a tuft of four hairs at basal two-fifths ; two long dentate artic- 

 ulated terminal processes, one short one and a small hair-tuft. Eyes 

 large, pointed. Mental plate small, with a median tooth and four on 

 each side, perpendicular, the first and second lateral ones subequal, the 

 second pointed, the third distant, the fourth moderate. Mandible quad- 

 rangular, convex without ; five large branched hairs on dorsal aspect in 

 a line, two smaller ones near them ; two pairs of flat appendages near 

 tip, the distal pair feathered ; an outer row of cilia ; terminal dentition 

 of eleven teeth, upper third and fourth produced ; two filaments above, 

 three within ; a square finely dentate process below ; a thick process at 

 end of dentition, one at base, between these a row of setae, the central 

 ones longest. Maxilla rounded rectangular, the palpus attached by a 

 narrow constriction ; numerous short setae and spines on inner aspect ; 

 palpus with round projecting base, a dendritic tuft within, five ter- 

 minal digits and two flattened appendages. Thorax rounded quadrate, 

 about as long as wide ; hairs short, consisting of branched hairs, single 

 hairs, and tufts, mesothorax sparsely haired. Abdomen stout, anterior 

 segments shorter; long feathered lateral hairs on first three segments, 

 double on first and second, single on third ; posterior hairs small, 

 smooth ; a dorsal series of six pairs of fan-shaped tufts on second to 

 seventh segments, the first pair sparse. Air-tube sessile, subquadrate, 

 roundedly angled posteriorly. Lateral plates of eighth segment poste- 

 riorly with a series of spines irregularly long and short. Anal segment 

 about as long as wide, with a small dorsal plate; dorsal brush a long 

 and a short tuft on each side ; a single long lateral hair below the plate ; 

 ventral brush well developed, of long branched tufts. Anal gills moder- 

 ate, about as long as the segment, slightly constricted centrally, blunt 

 pointed. 



"Egg. Fusiform, somewhat more pointed at one end than the other, 

 black, lower surface coarsely reticulate, dorsal surface granular ; lat- 

 eral floats occupying about half of the lateral margins and arcuately 

 produced, dorsally in the middle approaching very close to the median 

 line."
