closely rugose; the rugosity hardly distinguishable at maturity, but 

 indicated by faint transverse darker lines; the whole dark area con- 

 tinuous with cell i, which curves slightly against the tip of the peri- 

 thecium which it more or less completely conceals; its basal septum 

 indicated by a darker transverse line, its apex abruptly narrowed to 

 form a short curved finger-like projection which rises above the base 

 of the laterally projecting primary appendage. Perithecium rather 

 narrow, becoming yellowish, slightly concave near the base; the tip 

 becoming abruptly narrowed to a hyaline, short, curved, neck-like 

 termination; the apex bent, usually, toward cell i; the lip-cells rather 

 prominent and asymmetrical. Spores about 25 X 2 /x. Perithecia 

 50-60 X 6 M- Cell i 12.5 X 5.5 /x not including its distal projection, 

 which is 5 X 3 /x. 



Growing among the bristles just within the margin of the distal half 

 of the left elytron of Laccopkilus sp.. No. 2687, Grand Etang, Grenada, 

 B. W. I. 



This species is closely allied to C. marginatus, which was found on one 

 or two individuals from the same locality growing in its usual position 

 on the wing-margin nearer the base. The present species differs in 

 the presence of a series of closely set transverse ridges on cells/ to h, 

 which, although they are clearly defined in young individuals, might 

 readily escape notice in more mature specimens; and also in the form 

 of cell i, which is much longer, and is terminated by a short, narrow, 

 finger-like process; which, in C. marginatus, is replaced by a broad 

 truncate extension, as long or longer than the body of the cell itself, 

 from which it is also distinguished by a clearly defined transverse 

 hyaline area. 



Chitonomyces striatus nov. sp. 



Minute and slender. Basal cell hardly larger than the relatively 

 large foot, somewhat suffused with brown below, about the same diam- 

 eter throughout, hardly twice as long as broad; cell h horizontal, of 

 about the same width, distinguished by slight indentations, about 

 two thirds as long as broad; cells c, d and e subequal, the base of cell c 

 in contact with cell h; cell d, only, triangular; cell e slightly larger, 

 obliquely separated from cell /, and not in contact with cell h; cell / 

 relatively short, its rounded extremity obliquely and subsymmetrically 

 separated from cells g and h, which are nearly equal and as long or 

 longer than cell /; the region included by cells g and h, and the upper 

 half of cell /, tinged with brownish and crossed, on the right side only,
