Intestinal Protozoa in Termites 
(2) Dinenympha rugosa sp. nov. (Plate XV, figs. 69-72, 
and Text-fig. E, b). 
The body is long and slender as in the preceding species; but it is flat 
and ribbon-like, both sides being rather distinctly edged, and it tapers more 
abruptly at the posterior end. The length is almost equal to that of D. exilis 
but the width is about twice as great. The surface is not smooth but is pro¬ 
vided with high and distinct ridges, and the flagellar cords are markedly 
wavy. In young individuals with only four cords the ridges are particularly 
prominent. The axial filament is slender in this species, in contrast with 
D. exilis, being slightly thicker than the flagellar cords at the anterior portion 
and nearly equal to them at the hinder end, so that it is here hardly dis¬ 
tinguishable from them. The endoplasm appears remarkably coarse and is 
frequently vacuolated, showing an appearance quite different from that of 
D. exilis. The nucleus is situated near the middle of the body. It is commonly 
round in shape, but in some forms a peaked point is noticed, as shown in 
PI. XV, fig. 72, which may be taken as an indication of the existence of a con¬ 
nexion between the nucleus and a certain portion of the body. 
The species is harboured by Leucotermes speratus only. Forms of this type 
appear to be lacking in the descriptions of American authors. 
(3) Dinenympha nobilis sp. nov. (Plate XV, figs. 73-75, 
and Text-fig. E, c). 
The body assumes a club shape, gradually thickened towards the posterior 
end, and measures 30-60 p, in length and 5-10 p, in width. It is almost evenly 
rounded at both ends and is oval in cross section, the surface being quite 
smooth. Twisting of the body is slight, and the anterior portion is usually 
turned back, so that it assumes commonly the shape of a hook. The axial 
filament is rather indistinct. It is fairly thick anteriorly and becomes gradually 
slender towards the middle, where it is usually almost invisible; but it then 
becomes gradually thicker again posteriorly, and the extreme end is specially 
thickened. The endoplasm is of a peculiar appearance in this species: it is 
dark and finely granular during life, usually containing plenty of food debris. 
This species seems lacking in the Formosan species of termite, having been 
found in Leucotermes speratus only. No forms of this type seem to have been 
illustrated by the American authors. 
(4) Dinenympha leidyi sp. nov. (Plate XV, figs. 76 and 77, 
and Text-fig. E, d). 
The body is lanceolate and is fairly thick at the posterior portion. The 
ridges on the surface are very distinct and are arranged regularly. The axial 
filament is very indistinct, being made out with difficulty at the anterior 
region, and invisible at the posterior. The most remarkable feature of this 
form is that the free ends of the flagellar cords are conspicuously long, reaching
