liABOULHENiA Madeira; Thaxter. Plate UV, fig. 7. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. IN. r >. Dec, 1899. 



Perithecium united to receptacle for about two thirds of its length, pale straw-yellow becoming 

 brownish yellow, the whole tip clear contrasting black or blackish brown, the hyaline lip-edges turned 

 outward. Receptacle concolorous with perithecium, rather short, normal, cell V relatively large, its 

 upper margin free between the perithecium and the insertion-cell, the latter oblique, clear black, con- 

 trasting. Outer appendage often simple, elongate, sometimes once branched above its subbasal cell; 

 the branches divergent ; inner appendage consisting of a basal cell smaller than that of the outer, and 

 bearing one or two short branches commonly three-celled usually terminated by paired anthcridia. Spores 

 75 X (') ft. Perithecia 100 130 X 35 40 ft. Total length to tip of perithecium 225-250 ft; to insertion- 

 cell 175-210 /i. Appendages, longer 350 ft. 



On Calathus complanatus Dej., Paris Museum, No. 211, Madeira. On elytra. 



Through the enlargement of cell V, the broad insertion-cell in this species is thrown out free from the 

 perithecium, which is relatively small, and united to the receptacle up to a point not far below its broadly 

 blackened blunt apex. A sufficiently characteristic form, but without striking peculiarities.

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 175. Dec., 1899. 



Perithecium pale yellowish brown, slightly and evenly rounded, united to the receptacle as far as its 

 subterminal cells, the nearly symmetrical tip rather broad, often flattened distally, becoming deeply suf- 

 fused with blackish, except the narrow translucent margins of the lips. Receptacle pale yellowish, cell I 

 short and stout, distally suffused with blackish brown; cell VI very small, cell V free from the perithecium, 

 sometimes lateral. Insertion-cell thick and black, sometimes carried forward opposite the apex of the 

 perithecium through the elongation of cells IV and V. Outer appendage consisting of a large basal cell 

 several times longer than broad, which may bear terminally one or two branches, the outer sometimes 

 once branched, the branchlets very long, slender, tapering, hyaline or pale yellowish, more or less flexuous: 

 the inner appendage sometimes laterally placed, usually single, simple, consisting of two or three short 

 cells with one or two lateral antheridia and sometimes producing longer branchlets, the basal cell much 

 smaller than that of the outer appendage. Perithecia 110-120 X 35-40 ft. Total length to tip of peri- 

 thecium 200-275 ;i\ to insertion-cell 200-250 ft. Appendages, longest 675 ft. 



On Colpodcs agilis Chd., Jalapa, Mexico, Brit. Mus. (Biologia Coll.), No. 090; on C. evanescens 

 Bates, U. S. National Museum, Biologia Coll., Mexico. Elytra. 



Five specimens of this form in good condition have been examined, three from C. evanescens (fig. 20), 

 having somewhat longer appendages, but not differing otherwise from the two on C. agilis (fig. 21). The 

 tip of the perithecium appears to be turned in all cases so that the view is anterior, or posterior, instead of 

 lateral. The distal portion of the perithecium also may be so twisted that cell V is hardly visible beside 

 cell IV, a condition similar to that which is the normal one in L. paupcrcula. This species appears to be 

 allied to L. flagcllata and resembles L. Madeira; in some respects. 



Laboulbenia Orthomi Thaxter. Plate LIV, fig. 14 15. 

 Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 192. Dec, 1899. 

 Perithecium free, long and straight, slender, sometimes slightly inflated distally, deep clear brown; 

 the tip broad, prominent, not abruptly differentiated; the lips rather large and prominent, the lower 

 wall-cells as a rule elongated to form a hyaline neck, usually well marked and contrasting with the body 

 of the perithecium. Receptacle often shorter than the perithecium, faintly punctate, olive-brown, except 

 the hyaline or slightly yellowish basal cell, or pale dirty brownish yellow, with distal deeper olive suffusions. 

 Insertion-cell not as broad as cell IV. The outer appendage normally simple, the basal cell longer than 

 broad, blackened externally, as are also the two cells which lie above it, the subbasal cell and even 

 the cell above it rarely giving rise to erect simple branchlets. The inner appendage consisting of a
