 the perithecium. 



Laboulbenla Madagascarensis Thaxter. Plate LXI, fig. 12. 



Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 184. Dec, 1800. 



Perithecium free, mostly straight, the inner margin more convex, uniformly clear dark brown or 

 blackish except just below the black tip, abruptly distinguished from and contrasting with the receptacle; 

 the tip rather abruptly distinguished, straight or bent slightly inward, with hyaline lip-margins, the wall- 

 cells with a slight spiral turn. Receptacle hyaline or finally yellowish, cells III and VI about equal. 

 Insertion-cell opposite base of perithecium. Outer appendage consisting of a rather small basal cell, 

 its outer wall blackened, the blackening continuous with the insertion-cell, usually producing distally 

 two branches, an outer blackened externally or suffused with brown at its base and once branched, and 

 an inner usually simple and hyaline. The inner appendage consists of a basal cell like that of the outer, 

 and produces a single branch on either side which may be once branched, all the branchlets of both append- 

 ages rather stout and stiff, tapering, slightly curved outward, hyaline or becoming dirty yellowish. Peri- 

 theeia 100-120 X 40-45 \i. Total length to tip of perithecium 240-270 it; to insertion-cell 140-155 ft.

On margins of both elytra of a carabid allied to Harpalus, Paris Museum, No. 3, Madagasc ar. 



When young, this species is almost perfectly hyaline, the perithecium as well as the outer edge of the 

 outer appendage, soon assuming a rich dark brown, abruptly contrasting color. A somewhat similar and 

 larger form has been examined on II. roninus Bates from Japan, (Berlin Museum No. 1018), but is in 

 very bad condition. The species is nearly allied to or perhaps identical with certain other forms occurring 

 on species of Harpalus which have been examined from America and elsewhere, but which are in need of 

 further study. 



Laboulbenia Ophoni Thaxter. Plate LIV, fig. 11. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 190. Dec, 1809. 

 Perithecium free except at the base, short and stout, pale straw-yellow or nearly hyaline, variably 

 inflated; the inner margin often strongly convex, the black tip abruptly differentiated on its inner side, 

 black, contrasting, the lip-edges hyaline, turned slightly outward. Receptacle short, stout, normal, con- 

 colorous with the perithecium. Insertion-cell black, contrasting. The outer appendage divergent, 

 simple or once to three times branched, the ultimate branchlets distally attenuated; the inner appendage 

 consisting of a basal cell half as large as that of the outer, bearing a short branch on cither side which 

 may be several times branched, the antheridia borne in small groups. Spores 28 X 3 p. Perithecia 70 X 

 30-34 p.. Total length to tip of perithecium 1G5 //; to insertion-cell 85-100 p; width 40 p. Appendage-, 

 longest 200 p.

It has not seemed possible to include this species under any of the various forms known to occur on 

 Harpali, and their allies; but although the varied material is very constant and readily distinguishable, 

 the form is a very commonplace one, without marked distinctions. Always short and stout in form, 

 the insertion-cell, foot and perithecial tip contrasting strongly with the uniform pale transparent yellow 

 color of the plant as a whole, the inner appendages short, hardly ever extending to the tip of the perithecium, 

 the outer divergent with two to three tapering branches.
