322 PROTOZOOLOGY 



Genus Prolophomonas Cleveland. Similar to Eulophoinonas ; estab- 

 lished since Eulophomonas had not been seen by recent workers; 

 would become synonym "if Eulophomonas can be found in K. 

 flavicollis" (Cleveland). 



P, tocopola C. (Fig. 151, i). 14-19/i by 12-15iu; in Cryptocercus 

 punctulatus. 



Genus Joenia Grassi. Ellipsoidal; anterior portion capable of 

 forming pseudopodia; flagellar tufts in part directed posteriorly; 

 surface covered by numerous immobile short filamentous processes, 

 which some hold tobe symbiotic bacteria; nucleus spherical, anterior; 

 posterior to it a conspicuous axostyle composed of numerous axial 

 filaments, a parabasal apparatus surrounding it; xylophagous; in 

 termite gut. 



J. annectens G. (Fig. 151, j). In Kalotermes flavicollis. 



Genus Joenina Grassi. More complex in structure than that of 

 Joenia; flagella inserted at anterior end in a semi-circle; parabasal 

 bodies 2 elongated curved rods; feeding on wood fragments. 



J. pulchella G. In Porotermes adamsoni. 



Genus Joenopsis Cutler. Oval; large; a horseshoe-shaped pillar at 

 anterior end, flagella arising from it; some directed anteriorly, others 

 posteriori}^; parabasal bodies long rods; a strong axostyle; feeding 

 on bits of wood; in termite gut. 



J . polytricha C. In Archotermopsis wroughtoni; 95-129/i long. 



Genus Microjoenia Grassi. Small, pyriform; anterior end flat- 

 tened; flagella arranged in longitudinal rows; axostyle; parabasal 

 body simple; in termite gut. 



M. pyriformis Brown (Fig. 151, k). 44-52/i by 24-30^; in Reticuli- 

 termes hageni. 



Genus Mesojoenia Grassi. Large ; flagellar tuft spreads over a wide 

 area; distinct axostyle, bent at posterior end; 2 parabasal bodies; in 

 termite gut. 



M. decipiens G. In Kalotermes flavicollis. 



Genus Torquenympha Brown. Small; pyriform or top-form; axo- 

 style; radially symmetrical; 8 radially arranged parabasal bodies; 

 nucleus anterior; in termite gut. 



T. octoplus B. (Fig. 151, I). 15-26^ by 9-13^; in Reticulitermes 

 hesperus. 



Family 3 Hoplonymphidae Light 



Genus Hoplonympha Light. Slender fusiform, covered with thick, 

 rigid pellicular armor; each of the two flagellar tufts arises from a 

 plate connected with blepharoplast at anterior end; nucleus near 

 anterior extremity, more or less triangular in form; in termite gut.
