TABLE 1. 
Length of body Greatest breadth Number of legs 
Type 9 32 mm. 5 mm. 34 pairs 
Paratype 2 36 mm. 5 mm. 33 pairs 
Paratype o& 21 mm. | 4 mm. 30 pairs 
Although there is a difference in proportions in the two females th 
paratype is more fully expanded and consequently appears to be of 
more slender form. The type female and the male are of very simil: 
shape (see Plate 2, fig. 11). 
Coloration. © All three specimens are considerably decolorized fro) 
their preservation in alcohol, but still show very distinctly the gener; 
color-pattern of the body. To the naked eye, the legs and a broa 
stripe directly above them are much lighter than the dorsal regio: 
exhibiting a dull yellowish gray tint with distinct purplish cast whic 
is much more distinct in one specimen. In all three, the legs a 
decidedly paler than the pleural stiipe. The dorsal region, includir 
two thirds of the animal when seen from above, is much darker the 
the pleurae and differentiated into a complicated color-patter 
This consists in a light-colored median dorsal broad stripe, strong! 
constricted between each body segment, and a narrow very da 
beaded or interrupted median line, the interruptions of which coinei’ 
with the constrictions of the light stripe. Examined under a mici 
scope it is seen that the enlargements of the dorsal light stripe a 
rbomboidal in form, but coalescent for about half their greatest wid 
along the intersegmental lines, so that their margirs form a continuc 
longitudinal serrate line. The dark color is confined to the spe 
between the body folds and does not include the apices of the papill: 
even in the darkest portions of the stripe. The median blacker: 
line is discontinuous, passing over only five to seven folds on e@ 
segment and is much more strongly pigmented on the three or f’ 
alternate folds of each segmental group. The dorsal color-patt' 
fades out on the head and next segment, and continues to the poster’ 
extremity of the body, although paler on the last two or three s 
ments. The antennae are pale. 
Integument. The integumentary folds are very narrow on * 
ridges with the transverse grooves between them deep. At the le 1 
of each leg two of the folds are incomplete, extending only about h b
