and e irregularly disposed, small ; cell / long and narrow, its base but 

 slightly oblique, its distal end but slightly overlapped by cell g which 

 projects a short distance free above cell h; cell i more deeply suflFused, 

 sometimes amber-brown, long and stout, nearly straight or usually 

 variously and slightly bent, its basal septum horizontal, its tip asym- 

 metrical, the apex turned inward, of nearly the same diameter through- 

 out, extending for about half its length above the extremity of the 

 perithecium. Perithecium somewhat misshapen; tapering to the 

 base, where it is subtended by a distinct constriction; the second 

 external wall-cell forming a thick amber-brown margin, becoming 

 broader and ending in a more or less pronounced elevation, distally, 

 which subtends a second slight elevation followed by a constriction, 

 above which the tip is irregularly bent inward and to one side; the 

 apex blunt, with large slightly prominent lip-cells. A variably de- 

 veloped appendage arises from the wall-cell on the left side, next the 

 end of cell h, sometimes quite short, normally longer, somewhat in- 

 flated, distally recurved and pointed. Spores about 36 X 2 ju. Peri- 

 thecia 55-60 X 14 ix. Cell i 28-30 X 7 m- Total length to tip of 

 perithecium 70-75 X 20-22 ju. 



On the margin of the right elytron of Laccophilus sp. near the tip. 

 Grand Etang, Grenada, B. W. I., No. 26S7a. 



Most nearly related to C. rhyncostoma, from which it differs in many 

 respects, but more particularly in the relatively much shorter free 

 portion of cell g, and by the distorted tip of its perithecium. It was 

 not observed on any of the very numerous individuals of the same 

 host collected in Trinidad. 



Chitonomyces uncinulatus nov. sp. 



Uniform pale dirty yellowish brown, regularly curved throughout, 

 almost crescent shaped. Basal cell rather stout, tapering considerably 

 below; cell b about twice as broad as long, horizontal, the anterior 

 margin slightly concave, the posterior convex ; cells c, d and e subequal, 

 the base of cell c in contact with cell h; cell / very long and narrow, 

 its base only slightly oblique, distally slightly and symmetrically in- 

 truded between cells g and h, cell h extending free some distance above 

 the apex of cell </, and bent so as partly to overlap the perithecium; 

 cell i longer than broad, distally rounded, and terminated by the dark 

 insertion of the appendage. Perithecium long, curved outward, and 

 tapering evenly to a blunt apex; the outer margin slightly indented
