CHITONOMYCES AND RICKIA. y 



at the junction of the wall-cells; a long irregularly curved, slender, 

 darker appendage, ending in an abrupt bluntly pointed hook and 

 developed from one of the wall-cells, diverges irregularly from a point 

 beside the apex of cell h. Spores about 35 X 2 m. Perithecium 72 X 

 18 m; its appendage about 24-30 X 3.5 m- Total length to tip of 

 perithecium 100-120 X 27 ju. 



On the margin of the right elytron of Laccophilus sp. near the middle; 

 Sangre Grande, Trinidad, B. Vv. I., No. 2680. 



This species is well distinguished by its falcate habit, and the long, 

 hooked or subhelicoid appendage which arises from a point near the 

 apex of cell h. It is a singular fact that the two other species which 

 possess a somewhat similar appendage similarly placed, namely C. 

 rhyncostoma and C. cerviculatus, although otherwise quite different, 

 occupy a similar position on the host. 



Chitonomyces manubriolatus nov. sp. 



Rather short and stout, subsigmoid in habit, amber-yellow, becom- 

 ing rather deeply tinged with amber-brown. Basal cell short, sub- 

 triangular, abruptly bent, oblicjuely separated from cell b, which 

 overlaps it for nearly half its length on its posterior, convex, side; cell 

 b similar or somewhat smaller, together with the three cells above it, 

 more deeply tinged with clear amber-brown: cell c irregularly triangu- 

 lar, broader than cells d or e; cell d reaching to the posterior margin 

 for a short distance below cell e, which is thus wholly separated from 

 cell b; cell e flat, oblique, its transverse axis uniform throughout; cell/ 

 but slightly narrower below, externally concave, obliquely separated 

 from cells e and g, sometimes hardly twice as long as broad; cell g 

 externally convex, prolonged distally and externally to form a large, 

 free, deep amber-brown appendage, which may exceed the tip of the 

 perithecium, is suberect or variably divergent, projecting free from 

 the posterior margin, straight or irregularly bent below, narrowed at 

 the base, above which it is rather abruptly swollen, and tapering thence 

 to its blunt apex; cell h normal in form and position; cell i nearly 

 hyaline, tapering somewhat to its rounded extremity, subsymmetrical, 

 erect, about twice as long as broad, or less. Perithecium strongly 

 convex externally, the outline of its margin not quite even, owing to 

 slight indentations at the junction of the wall-cells; the tip somewhat 

 distinguished, curved inward, short, stout, the outer lip-cell forming 

 a rounded prominence, the inner broad and flat, the lateral ones
