of about fourteen spines. This ctenidium is continued downward on 
each side by about nine very indistinct pseudo-spines, these shadowy 
spines overlapping the mesothorax. At the lower border of the prono- 
tum is a long bristle, above this another smaller one and near the 
dorsal margin one more. In the male there is a pronotal ctenidium 
of about thirty-eight spines. The bases of these spines form a com- 
pound curve, above the convexity being anterior while laterally the 
anterior margin is concave, and this concavity is filled in by appar- 
ently a duplicate set of shadowy pseudo-spines, and between each of 
these pseudo-spines is an indistinct bristle. The mesonotum is short 
and contains on its dorsal median surface a thickened chitinous patch, 
‘this patch being prolonged over the metanotum and containing a few 
long hairs. The metanotum is the longest of the thoracic nota, thick- 
ened on its dorsal median surface and contains in this thickened patch 
an anterior and posterior row of about six long hairs placed very close 
together and on its lateral surface is a long bristle. ; 
The mesothorax is not divided by a vertical suture and has, a little 
anterior to its middle, one long bristle in the female and two in the 
male, and on its posterior border two long bristles one above and one 
below the second thoracic stigma. The episternum of the metathorax 
is fused with the metanotum and contains one short and one long 
bristle, the metasternum has one short, stout bristle placed high up’ 
and the epimerum in the male has four or five large bristles and in 
the female four. 
The Abdomen.—The abdominal tergites from the first to sixth, have 
in the median line of the dorsal surface a distinct saddle-shaped chitin- 
ous patch and a set of short, stout teeth or spines. These spines over- 
hang the chitinous patch of the next posterior segment. 
The first, second and sixth have five teeth each, and the third, fourth 
and fifth seven each. The three middle teeth are in each case the larg- 
est and blackest . The seventh tergite contains the thickened patch, but 
in place of the teeth has at its apex, in the female, two short, stout 
antipygidial bristles and in the male one bristle on each side. Anterior 
to the spines in each tergite, in the median line are several hairs. 
Laterally on each tergite are two bristles, one below and one above the 
stigma. The sternites in the male from the third to the eighth con- 
tain a single row of six bristles while in the female there is on the third 
a row of four bristles and on the second sternite only two bristles. 
The eighth tergite has just at the upper edge of the pygidium a small 
hook-like process and laterally in the female there are four bristles 
placed one above the other. Below there is a patch of about seven 
bristles, more or less in line, on each side and above these close to the 
margin about eight small bristles. The eighth sternite is very narrow. 
The stylet is long, narrow, cylindrical, as wide at the tip as at the base,
