6 THAXTER. 



35 X 12 M- Cell i 5.5 X 9 m- Total length to tip of perithecium 

 90-100 X 23-27 m- 



On the outer edge of the right elytron of Laccophilus sp., near the 

 middle. Grand Etang, Grenada, No. 2687, and Sangre Grande, 

 Trinidad, B. W. I., No. 2684. 



A peculiarly distorted form, well distinguished by its two appendages 

 and the stout neck-like termination of its perithecium. 



Chitonomyces introversus nov. sp. 



Distally flat and broad, becoming roughly triangular in outline, 

 rather evenly suffused with dull amber brown; basal cell relatively 

 large, curved below, much broader distally; cell h horizontal, greatly 

 flattened; cell c very small; cell d broad and flattened; cell e some- 

 w^hat larger, subtriangular, obliquely separated from cell /, which is 

 long and narrow; its lumen, which is abruptly broader distally, 

 otherwise nearly obliterated by the unusual thickness of the outer 

 wall; the rest of the receptacle turned abruptly inward so that it lies 

 sometimes almost at right angles. to the general vertical axis; cell g 

 relatively long, its base posterior, its upper (outer) margin more or less 

 distinctly concave; cell h more than half as long, also lying obliquely 

 or subhorizontally; cell i paler, slightly longer than broad, its inner 

 (lower) side flattened and lying just above a shelf-like prominence 

 that subtends the tip on the left side of the perithecium. The latter 

 broad and short, its tip short, bent abruptly to the right away from 

 the subtending prominence; so that, when the perithecium lies at the 

 right, it is viewed end on; the apex irregularly rather coarsely lobed. 

 Spores lying nearly horizontally in the upper part of the perithecium 

 about 36 X 3.6 m- Body of the perithecium, exclusive of tip, 54-60 X 

 27-32 iJL. Total length 80-95 /x; the three lateral dimensions 40 X 75 

 X 82-50 X 86 X 90 fx. 



On the posterior legs of Laccophilus sp. No. 2687, Grand Etang, 

 Grenada, B. \V. I. 



A rare species easily distinguished by its triangular form, and the 

 horizontal position of cells g-i. 



Chitonomyces oedipus nov. sp. 



]\Iore or less deeply and uniformly tinged with dull amber-brown; 

 short and stout. Basal cell inflated below; the inflated portion some-
