tacle short and rather stout, cells II IV becoming externally blackish brown, the resl concolorous with 

 the perithcciuin ; colls III and IV rather prominent. Outer appendage becoming w holly opaque, its 

 successive cells indistinguishable as are the basal and insertion-cells, consisting of a blackened axis creel 

 or bent outward, from the inner side of which arise several more or less blackened branches, the basal por- 

 tion of the appendage only, as a rule, remaining. The inner appendage, consisting of a basal cell w hich 

 is usually indistinguishable from (he insertion-cell, being quite opaque, producing .1 branch on cither side, 

 the axis of the branches erect, becoming blackened and opaque, except the inner margins of the distal 

 cells, bearing externally from six to ten or even more branohlels which are more or less deeply suffused. 

 IVritheeium 130-150 X 30-33 //. Total length to tip of perithecium 190-240 p; to insertion-cell 90- 

 130 fi. Greatest width 40-50 /i. Appendages longest (broken) 185 //. 



On inferior surface of abdomen, and on elytra of Miscelus Javanus King., Elope Collection, No. 

 304, Java; on Misrcliis sp., Paris Museum, No. 114, New Guinea. 



This somewhat variable species occurs on the elytra and abdomen of its host. Its small receptacle 

 and relatively large perithecium, together with its peculiar appendages, give it, like the allied L. imitans, 

 a general habit which strongly suggests some species of Corethromyces. The main axis of the outer append- 

 age, as well as the main branches of the inner, appear to result from successive proliferation and may 

 be quite opaque. The species is very closely allied to L. Misceli from the Moluccas, which may prove 

 merely a paler variety. The figures represent specimens from the type slide on M. Javanus from Java.

Perithecium free, long and slender, translucent, pale brownish olive, slightly narrowed at the base 

 to form a short paler stalk which lies opposite the insertion-cell; the tip long, not very abruptly distin- 

 guished, paler below, straight or turned slightly outward, distally blackened on the inner side; the lips 

 variable, rather prominent. Receptacle rather short and stout, darker olive-brown; the basal cell pale 

 yellowish. Insertion-cell nearly as broad as cells IV-V. Basal cell of outer appendage blackish brown 

 externally, bearing a single terminal branch of less diameter, externally suffused with blackish brow n, 

 slightly curved outward and bearing two or three branchlets from the inner side which are .hyaline, their 

 basal cells somewhat suffused w ith brown; the basal cell of the inner appendage smaller than that of the 

 outer, nearly hyaline and bearing a branch on either side similar to the outer appendage; both the ap- 

 pendages and their branches erect, subappressed. Perithecia including base 145-180 /i. Total length 

 to tip of perithecium 240-300 /<; to insertion-cell 90-130 /<; greatest width 35-40 fi. Appendages, longer 

 150 p. 



At base of posterior legs of Miscelus sp., Paris Museum, No. 114 bis, Isles des Moluques. 



This species is too closely allied to L. Corethropsis, of which it will probably prove to be merely a 

 variety. It differs in its paler color, and erect and unsuffused appendages, which are however, very 

 similar in structure. The general appearance of the two is distinctly different and they are kept apart 

 provisionally until more and better material of both forms can be examined.

 Perithecium pale olivaceous, the inner margin convex, the outer nearly straight; the tip rather 

 abruptly distinguished, blackened, but not uniformly, below the inner lip-edges which are prominent, oliva- 

 ceous, translucent, the right inner lip prolonged to form a slender nearly hyaline finger-like projection, 

 the tip of which is blunt and somewhat swollen. Receptacle relatively large dull olivaceous, cells, II, 

 III, and IV sometimes becoming blackish brown externally, cells III and IV rather large; the insertion- 

 cell close to the base of the perithecium, half as broad as cells IV and V. Outer appendage curved strongly 

 outward, opaque and indistinguishable from the insertion-cell, bearing three or four branches from its 

 convex side which are mostly once branched; the inner appendage consisting of a small basal cell, bearing
