guished on the inner side, somewhat longer than broad, of the same 

 diameter throughout, distally flattened or bluntly rounded, with 

 slightly projecting lips around the median terminal pore. Spores 

 40 X 2.5 fi. Perithecia 86-100 X 10-12 fx. Cell i 12 X 5.5 (x. 

 Total length to tip of perithecium 120-155 X 12-16 /x. 



On the tip of the right elytron of Laccophilus sp. ; Sangre Grande, 

 Trinidad, B. W. I., No. 2680 b. 



Although this species is not marked by any of the bizarre charac- 

 teristics so frequently met with in the genus, it does not seem closely 

 allied to any species known to me. It is most clearly distinguished 

 by its slender form, the obliquity of cell b, and by the mottled suffusion 

 on one side of the tip of the perithecium. 



Chitonomyces longirostratus nov. sp. 



Pale straw-yellow. Foot small; basal cell more or less, often 

 greatly elongated, becoming opaque; cell h squarish, or longer than 

 broad ; cell c similar to, or somewhat smaller than cell b ; cells d and e 

 separated from cell b by the whole length of cell c, both small; cell / 

 long and narrow, its base hardly oblique, slightly overlapped by cell g; 

 cell i hyaline, four times longer than broad, the apex slightly asym- 

 metrical. Perithecium subclavate, strongly curved sidewise, the tip 

 abruptly distinguished, enormously elongated, opaque on one side, 

 translucent purplish brown on the other, of about the same diameter 

 throughout, perfectly straight and rigid; the apex short, distinguished 

 on one side; the lips hyaline and somewhat prominent. Spores about 

 30 X 2 M- Perithecia, body 65-78 X 18-20 fx, the tip 245-260 X 8- 

 II fjL. Total length, to base of perithecia! tip, 140-156 ijl. 



On the outer margin, at the tip, of the right elytron of Laccophilus 

 sp., Sangre Grande, Trinidad, B. W. I., No. 2680a. 



A most peculiar species, clearly distinguished by the extraordinary 

 development of its black and remarkably elongated, stiff, black peri- 

 thecial tip; which is bent to one side in such a fashion that the 

 body of the perithecium and the receptacle are turned edgewise in 

 preparations under a cover glass, and the arrangement of cells f to g 

 is thus not determinable in fully developed individuals after they are 

 mounted. Four mature and several younger individuals have been 

 examined.
