Thorax.— The pronotum bears one row of bristles and a 
comb of' 21 spines. The meso- and metanotum have each 3 
rows of bristles, the anterior row being incomplete. The epis- 
ternum of the metathorax has no bristles, while the epimerum 
bears 6 long ones (3, 3) and 1 or 2 short ones. 
Abdomen. — The tergites bear 2 rows of bristles, there being 
one or more additional bristles in front representing a third 
row. The second tergite has one or two slender, bristle-hke 
spines on each side at the apical edge. The seventh tergite 
bears 1 apical bristle, which is short, being about as long as 
the third postmedian bristle of this segment. The sternites of 
segments 3 to 7 have a row of 4 long bristles on each side, 
the basal sternite, however, bearing but 1 bristle. 
Legs. — The mid and hind coxie are rather narrow and long, 
both having a single bristle posteriorly at the apex. There are 
no short spines on the inside of the hind coxa. The fore fe- 
mur has on the outside 1 subapical bristle and 4 or 5 lateral 
ones. The mid and hind femora bear 2 subapical bristles on 
the outside and 1 on the inside. There are about 18 bristles 
on the outer surface of the hiiul tibia. The hind tibia has 7 
dorsal notches. The longest dorsal bi'istle of this tibia is hardly 
twice as long as the tibia is broad, the longest apical bristle 
being only about one-third the length of the fírst hind tarsal- 
segment. The tibiie have a long and a short bristle in most of 
the notches. The first hind-tarsal segment is nearly as long as 
the hind tibia, the bristles situated at its posterior side being 
rather long and very thin. The thick apical bristles of this 
segment are short, the posterior one being only one-third the 
length of the second segment and the anterior one being about 
as long as the first segment is broad. The fifth segment bears 
in all the tarsi 4 strong lateral bristles and a sub-basal pair 
which are placed on the ventral surface in between the first 
lateral pair. 
Modified segments. — $ The large eighth sternite bears a 
row of 5 long bristles on the side. The clasperlias a short roun-
