of various species and from widely different localities, as well as of forms of the Ban* Moral Ivim v\hi< h 
0CCU7 on allied hosts, renders any definite decision as to the limits of this Bpecie.s a mailer of gfeal diffi- 
eulty. The East Indian forms approach very closely indeed to L. fkgdhta, though they retain the ((dur- 
ation of the type, and the slightly individual peritheciaJ tip. The ba d odl of the outer ap|>cndage is 
either not at all or very inconspicuously inflated, and 01 form from the Philippines can hardly b. dis- 
lished from typical L. flagellata. On other American hosts, however, the inflation of the basal cell 
becomes even more pronounced than it is in the type, the coloration changes, and on speciea of Inn, Piva- 
codera, Cymindis, Euproctus, Aperies and Callida a form occurs which, wiihom comparison, I should not 
have hesitated to separate specifically. Such a separation may eventually prove desirable, yet 1 hav< 
thought it best to group all these forms under the pn nt name until they can l» more carefully revised 
and illustrated. The material thus grouped has been obtained from the following hosts. British Museum;

Perithecium variously suffused with dark olive brown, sometimes transparent brownish yellow, 
becoming nearly opaque, about one cjuarter, or only the tip, free from the receptacle, rather short and 
stout; the tip black, often bent outward, tapering rather abruptly; the lip-edges hyaline tther promi- 
nent and outwardly oblique. Receptacle pale reddish amber or yellowish, becoming variously suffused 
with dark olive-brown, especially distally; the basal cell more commonly narrow and hyaline below; 
abruptly broader and suffused with dark olive-brown below the base of cell II, which is often abruptly 
broader through a slight inflation in this region, and similarly suffused, the suffusions often faint; ce" 
III to V often deeply suffused with olive-brown, faintly striate; cells III and IV subequal; cell NT extending 
more or less prominently upward along the inner margin of the perithecium which is further bordered 
by cells III and IV; the insertion-cell carried obliquely outward by these modification^ Basal cell of 
the outer appendage usually hvaline, bearing normally two branches; the ba cell of the inner hyaline. 
that of the outer often small and blackened, bearing two branchlets; the outer shorter, more slender, 
opaque (usually broken); the basal cell of the inner appendage similar to that of the outer, often pro- 
truding somewhat inward, bearing two branches like the outer, or ie often laterally, that next the peri- 
thecium bearing one or more antheridial branchlets; the antheridia terminal m groups of two or more 
sometimes densely clustered; the other bearing similar antheridial branchlets or more often one or more 
long sterile branchlets like the outer appendage; all the sterile branches usually elongated m a jweeping 
cum toward the perithecium, commonly rich brown or nearly opaque, sometimes hyaline, sometimes 
multiplied by branching close to the base. Spores 65 X 5 fi. Perithecia 90-1 25 X 40 .... ... Keceptaele
