wise identical with it. The species appears to be allied to L. subconstricta, L. aristata, and several others 
of the numerous and varied forms which occur on these and other nearly related genera of East Indian 
Carabidte, The maximum measurements given above apply to the form on Cataxcopus.

Perithecium less than one half free, rather small, curved strongly and evenly toward the appendages, 
evenly suffused with dark brown or lighter distally; the tip black, not abruptly distinguished, the lips 
distinct with a broad hyaline margin about the pore. Receptacle dull amber-yellow, cells IV and V, some- 
times cell III, less deeply suffused with brown; cell I narrow, straight, but slightly enlarged distally; cell 
II abruptly much larger, symmetrically and prominently constricted in the middle; cells III and IV rela- 
tively, large and broad. Outer appendage simple, the basal cell moderately large; externally or wholly 
blackened; the rest of the appendage straight, rigid, directed across the tip of the perithecium: inner 
appendage consisting of a smaller basal cell which bears one or two branches similar to the outer append- 
age. Perithecia 85 X 25 pu Total length to tip of perithecium about 200 //; to insertion-cell 165 /*; 
greatest width 50 //. Appendages, broken, about 150 /* or a little more.

This specii s is very closely allied to L. tenuis, but differs in its short stout perithecium, and in the 
peculiar form of its receptacle, which does not vary in the five types.

Slender, nearly uniform pale dirty yellowish throughout. Perithecium relatively small with a faint 
brownish tinge, about four fifths free, erect, straight; the tip fairly well distinguished, the inner lip-cells 
large, prominent, rounded, the lip-edges outwardly oblique. Receptacle slender and long, punctate', 
the subbasal cell much longer than the basal, nearly isodiametric, or swollen above the basal cell and 
broader than the distal part of the receptacle, which is separated from its distal end by a prominent con- 
striction; cells III and VI subequal, or cell III larger; cell V verv small: cell IV longer than broad, 
becoming externally tinged with brownish. Insertion-cell relatively thick, free, narrow. Appendages 
becoming wholly dark brown, in contrast to the rest of the plant; the outer simple, or once furcate above

11ns pale dirty brownish yellow, evenly colored species is well distinguished by the peculiar con- 
formation of its receptacle; cell II being greatly enlarged, and the receptacle immediately above it dis- 
tinctly narrowed, forming a constriction. The appendages become verv dark contrasting brown; but 
m all the specimens examined, which are sufliciently numerous, though not in the best condition, the 
perithecium remains coneolorons with the receptacle and without dark shades.
