me best, in order to avoid too muck repetition in the following descriptions of species, to describe
liere what one might call the normal type of this li mb in this genus. When a character of this
limb is not specially mentioned in the following descriptions of species, it thus means that in
the species in question this character agrees with what is denoted here as the most usual state
of affairs. — This limb shows no, or at any rate scarcely perceptible, dimorphism. — P r o
topo di te: Coxale: The too thed edge of the pars incisiva is in most cases of about the same
type as that reproduced below in fig. 16 of C. symmetrica, i. e. the most anterior tooth is very
powerful, smooth, low, broad, rather transversally and evenly cut off distally; the others are
also smooth and decrease, though somewhat irregularly, in size and strength the more posteriorly
they are situated; the anterior ones are moderately large and somewhat irregularly triangulär,
the posterior ones are very small ; the posterior part of this edge can conveniently be described
in this type as being irregularly undulated. The number of these teeth is rather difficult to
establish with certainty on account of the small size of the posterior teeth and it varies somewhat
even within the species. The toothed edge seldom varies from this type. In some species,
however, variations were observed with regard to the teeth situated behind the large anterior
tooth. These are sometimes subequal — or else the most posterior one is even somewhat more
powerful than its neighbours —• and are all relatively smaller than the anterior ones of these
teeth in the type described above, irregularly triangulär and smooth (cf. my figure 9 of C.
rotundata G. W. Müller). In one species (cf. my figure 6 of C. Gaussi) this toothed edge ends
posteriorly with a low, broad, irregularly rounded tooth; the teeth nearest to the large anterior one
are of about the same type as in the ,,normal type“ described above, but somewhat less relativelv;
the other teeth decrease in size and strength the more posteriorly they are situated; the part
just in front of the broad rounded posterior tooth is finely serrulated. The two tooth-lists and
the masticatory pad show such great variability that it did not seem to me convenient to
describe them in this connection. I need only point out here that the tooth-lists often exhibit
a certain variability even within the species and that the masticatory pad is always well developed.
Along the posterior edge of the pad-like part of the pars incisiva there are four more or
less broad lancet-bristles and also a large number of rather short or moderately long bristles,
situated close together and simple or somewhat bifurcated distally. Basale: This is in most
cases of about the type reproduced by me in fig. 22 of G. symmetrica; its relative length is in
exceptional cases somewhat less and it has sometimes a relatively stronger endite. The six
teeth on the distal edge of the endite are in most cases all of about the same size and type.
These teeth have most frequently the following type: They are moderately large and
almost equilaterally triangulär; about the proximal halves of the anterior and posterior
edges are excèedingly finely serrnlated; in a number of cases this serrulation is rather
strong. In exceptional cases (cf. my fig. 10 of C. Gaussi) these teeth are relatively low,
the proximal serrate teeth on one or both of the edges are, on the other hånd, very powerfrd,
i. e. the difference between the main points of these teeth and the serrate teeth has almost
disappeared in this type. The two posterior processes on this edge are subequal,
moderately strong, bare or furnished with a few secondary spines; the distal one of them is of the
tube-bristle type, the proximal one, which is situated rather slightly proximally of the former
