Chilopoda of the Australian Continent. 455 
tudinal lateral yellow stripe lying midway between the lateral 
border and the sulcus, the margin of each tergum and the 
upper portion of the pleural membrane being green ; some- 
times this yellow stripe is broad and extends right to the 
margin, in which case there is no green on the pleura; at 
other times the median green stripe spreads laterally and 
almost obliterates the yellow, and it is always a little wider 
than the space between the furrows; it begins either upon 
the second or first tergum; the latter, however, is, like the 
head, generally uniformly deep green; antennz green, indis- 
tinctly banded with yellow basally ; toxicognaths, legs, and 
sternum reddish or greenish yellow; anal legs prettily banded 
with green and yellow, being green with a broad transverse 
yellow band on the basal half of each segment. 
In structural features this species resembles the form that 
passes as f. morsicans of Linnzeus, of which it is, perhaps, a 
descendant, modified since artificial introduction into Aus- 
tralia, where it appears to be the only indigenous species of 
the genus Rhombocephalus. 
Total length up to 56 millim. 
Loc. Perth (H. W. J. Turner); New South Wales (W. W. 
Froggatt). Haase’s specimen was recorded as doubtfully from 
Adelaide. 
The two New South Wales specimens have the yellow 
bands broader and more sharply defined than in the examples 
from Perth. More material, however, must be examined 
before the question as to the racial value of this feature can 
be established. 
Genus CORMOCEPHALUS, Newp. 
Representatives of this genus are the prevalent forms of 
Scolopendroids met with in South Australia. The genus 
occurs also in New Zealand and other islands adjacent to 
Australia, in Madagascar, in South Africa (where it is abun- 
dant), with a few outlying species in Ceylon and India. 
The Australian species fall into two sections. The first, 
typified by C. aurantiipes, has three spines in a single series 
on the outer side of the under surface of the femur of the anal 
leg, whereas in the second, typified by Westwoodit, the spines 
in question are four in number and biserial.
