suffused with olive brown, the latter prominent below the Mack insertion-cell; i II II I slightly longer than 
cell VI which lies erect beside it. The outer appendage consisting of a somewhat incurved seriei of about 
three obliquely superposed cells, the basal large, externally suffused with olive-brown, the test wicci ivelv 
smaller, yellowish, all bearing distally a branch from a nearly horizontal l>as< , the branch < s mostly once 01

At the base of the posterior legs of Lebia sp., Java, Rouver, No. 1398. 
A smaller form, which cannot be separated from this species, occurs on the legs of the host (fig. I), 
and differs in the blunt straight tip of its perithecium, the absence of dark suffusions, except in the append 
ages and at the tip of the perithecium, in its ill developed appendages, and in the greater prominence of 
the cells about the base of the perithecium. The latter character is one which distinguishes this species 
from any other known to me, and the type form represented in fig. 3, can hardly be confused with any 
other. It appears to be somewhat allied to L. insignis, but not at all closely. 
Laboulbe.via Australikxsis Thaxter. 
Additional material of this species on Acrogcnys hirsute from Australia has been obtained from tlx 
British Museum No. C68 and from the Berlin Museum No. 943. The branches of the appendages apj>ear 
to be very brittle, and in most of the adults are so broken that their true character ifl obscured. The vart- 
i 
able basal cell of the outer appendage, unlike those of the specimens figured in my Mont 
more or less completely and deeply suffused, and in general gives rise to an outer and an inner branch; tic 
inner hyaline and usually furcate above its basal cell; the successive cells of the main axis of the outer, 
about three in number, more or less deeply suffused, especially externally, each giving rise distally, »me- 
times from both the inner and outer angles, to rigid branchlets, which may be sample or, especially in the 
lowest, commonly bear several secondary branchlets which grow upward. This type of branching seel 
in the outer appendage is unusual, and the species is well distinguished.

Perithecium short and stout, less than half free from the receptacle, nearly opaque blackish brown 
lighter distally, the short broad blunt black tip rather abruptly distinguished on the inner side. Recep- 
tacle rather stout, cells I and II dirty yellowish or subhyaline, the n I more or less deeply suffused with 
blackish brown; all the cells except cell I marked by fine transverse striatums more distinct on the suffua d 
portions; cells III and IV large and prominent, the insertion-cell broad but narrower than cells 1\ \ 
Outer appendage consisting of a short irregular cell abruptly prominent externally above the insertion-cell, 
narrowed distally and bearing two branches antero-posteriorly, the outer externally deep blackish brown, 
once branched, its outer branchlet blackened and also branched, the inner consisting of a short basal cell 
which bears an inner and an outer branchlet, all the branchlets pale brown, except the outermost which 
is blackened, curved outward: the inner appendage consisting of a basal cell smaller than that ol the 
outer, irregular and bearing a branch on either side; each once branched, the branchlets like those ol

A stout species, the form of which is similar in general to that of L. Mmfapm* the distal part ol h ; 
I receptacle (cells III-V) being as large as the whole remainder. The appendages are, however, qui! af- 
ferent, as is the form and position of the perithecium. But two specimens of thespeaes ha* b en exam- 
ined. in both nfwhU thp tin* nf iho ultimate branchlets of the appendages are broken.
