Pcrithccium becoming wholly suffused with blackish brown, straight, thick-walled, cylindrical 
or slightly inflated, the apex truncate or slightly oblique outward, <he oufor lip nearly hyaline. 
Appendages arising opposite the base of the perithcciuin, consisting of two equally broad basnl 
cells, the inner shorter, bearing each a single cell from which arise from three to five tisually 
simple branches hardly cxccedhig the pcrithccium, Ihu lower cells usually inflated, the septa 
blackened, as is the outer wall of the external basal cell. Roceptncle normal, cells 111 and IV 
blackened externally or wholly, the suffusion becoming general in older individuals, in which 
the basal cells of the pcrithccium may become elongated to form a neck-like base free from 
the insertion-cell of the appendages, which becomes i)ushed out quite free from the pcrithccium 
by the elongation of cells IV and V. Perithccia, 100-150 x 35-40 /a. Longer appendages, 250- 
330 fjL. Total length to ti]) of pcrithccium, 240-330 /x. 
On elytra and thorax of Panagmis crucigerus Say, and P.fasciatua Say, Southern United 
States. 
Specimens occurring upon P. crucigerus are decidedly larger and more elongate than those 
observed upon the smaller species. The form belongs to the group of which L. Gahriice may be 
taken as the type, in which the lower scries of wall-cells tends to form a neck-like base. The 
inflated cells of the appendages recall those of L. infiata, but the two species are not related. 
The hosts affected are myrmccophilus Carabida^, inhabiting ants' nests.

Perithecium as in the preceding species, less deeply suffused and supported in older individuals 
by a more or less neck-like base. Appendages consisting of two closely united basal cells; 
the outer much the largest, and giving rise directly to two branches, the outer deeply suffused 
with olive-brown, the inner once or twice branched, hyaline or with suffused tips. The inner 
basal cell gives rise to one or two branches, simple or once or twice branched ; the insertion-cell 
black, thick and rather narrow, placed opposite the base of the perithecium. Receptacle nor- 
mal, except for the eventually neck-like hyaline base of the perithecium, hyaline, becoming suf- 
fused with olive-brown, especially in the region of cells II, III, and VI. Spores, 74 x5.5/t. 
Perithccia, 110-148 X 38 /i. Longest appendages, 222 /x. Total length to tip of perithecium, 
220-300 ^. 
On elytra of Acrogenys Tiirsuta McLean, Australia. 
This species appears to be allied to L. Panagcei, although the appendages are very different 
in character. The available material is not abundant and is in rather poor condition, yet ihe 
species seems sufficiently well marked.
