CHITONOMYCES AND RICKIA. 11 



Chitonomyces bicolor nov. sp. 



Hyaline or becoming faintly tinged with dirty yellowish brown, 

 except the large opaque terminal cell. Foot sharply pointed and 

 basally swollen. Basal cell two or three times longer than broad, 

 tapering somewhat to its base; cell b small, flattened, horizontal; cells 

 c, d and e subequal; cell d an isosceles triangle, pointed above; cells 

 c and e subtriangular and similar, cell e somewhat larger; cell/ long 

 and narrow, its base extending downward external to cell e for less 

 than half the latter's length; cell g somewhat broader than cell h, its 

 base slightly overlapping the termination of cell /; cell i extending to, 

 or slightly higher than, the apex of the perithecium, free, blackish, 

 somewhat translucent, opaque externally and distally, abruptly and 

 more or less strongly curved outward distally, the convex margin 

 roughened or tuberculate. Perithecium externally rather strongly 

 convex below, tapering somewhat, distally, to the broadly spreading 

 as^Tiimetrical termination ; which is outwardly prominent and rounded, 

 and may be suffused; a much more prominent free rounded projection 

 directed inward, and often wholly or partly overlapping cell i; a slight 

 median papillate projection also arises near the pore. Spores about 

 24 X 2 M- Perithecia 60-80 X 12-14 fx. Cell i about 30-7 /x. Total 

 length to tip of perithecium 100-125 /x. 



On the outer margin of the left elytron of Laccophilus sp., Sangre 

 Grande, Trinidad, No. 2684; and on the same species at the Grand 

 Etang, Grenada, B. W. I., No. 2687. 



A species most nearly allied to C. Javamcus, but distinguished 

 especially by the different modification of cell i, the opacity of which 

 does not involve cell g, as in the Javan species. 



Chitonomyces seticolus nov. sp. 



Basal cell about twice as long as broad, slightly broader distally; 

 cell b horizontal, broader than long, distinguished above and below 

 by well defined constrictions : cells c and d small, subequal, the latter 

 an isosceles triangle, distally pointed; cell e somewhat larger and 

 obliquely adjusted to the base of cell /, which extends more than half 

 way to its base: the remaining cells all becoming opaque, or nearly so, 

 forming a black-brown margin to the perithecium, externally symmet- 

 rically convex, somewhat translucent along its inner edge, and rather
