the whole tip thus armed strongly suggesting the head of a two- 

 horned rhinoceros. The species was common in the vicinity of Port 

 of Spain, but individuals were found only in the depressions near the 

 bases of the elytra. The receptacle is twisted one quarter in relation 

 to the perithecium, in most specimens; so that, when the latter lies 

 flat, the receptacle is usually viewed edgewise. 



Laboulbenia Hottentottae nov. sp. 



Receptacle rather slender, sometimes slightly geniculate between 

 cells II and III; cell I usually quite hyaline; cells II— III becoming 

 more or less deeply suffused, or nearly opaque; cell II sometimes 

 abruptly broader than cell I, but always shorter; separated from cell 

 VI by a horizontal, from cell III by a very oblique partition; cells 

 III and IV subequal, separated by a very oblique partition; cell V 

 narrow, triangular, nearly hyaline; cell VI suffused, distinguished 

 above and below by an indentation, obliquely separated from the cells 

 above, which form a broad almost stalk-like base to the perithecium. 

 Insertion-cell suffused, but not blackened, rather thick. Basal cell 

 of outer appendage somewhat longer than broad, brown, giving rise to 

 a short hyaline erect subterminal branch on the inner side; the sub- 

 basal cell colored like the basal, somewhat longer; the rest of the 

 appendage hyaline, few-celled, short; basal cell of the inner appendage 

 much smaller than that of the outer, concolorous; producing a branch 

 on either side, each usually once branched; the branches sometimes 

 exceeding the perithecium in length, hyaline, except the brownish 

 basal cells. Perithecium wholly free, rather long and slender, often 

 nearly symmetrically inflated, deep rich brown, tapering evenly 

 distally; the tip hardly if at all distinguished, darker along the inner 

 side; the apex blunt, the lip-edges subhyaline about the pore, some- 

 times slightly oblique outward; a slight projection usually visible 

 next the pore. Perithecia, exclusive of basal cells, 90-125 X 18-25 ju. 

 Receptacle 90-110 X 25-32 fx. Appendages, longest 120 yi. Total 

 length to tip of perithecium 160-200 ix. 



On elytra etc. of Lema Hottentotta Lac, Zanzibar (M. C. Z.): 

 crowded near tips of elytra. 



This species usually has a somewhat falcate or slightly curved 

 habit, and is rather slender in form. Although apparently allied to 

 L. Bruchii, its appendages and receptacle separate it at once from any 

 of the forms of that species. The material available is abundant and 

 in good condition.
