A new subfamlly Rotylenchulinae ls proposed under the family Hoplolalmidae to Include the genus Rotylenchus. Interrelationships of the genera ol tKe family Tylenchldae are discussed. Ottolenchus n.subg. ls proposed under the genui 'Tylenchus. Tylenchus (Ottolenchus) egulsetus n.subg., n.sp. ls described from soli around the roots of Casvarlna egulsetlfolla at Allgarh, Uttah Pradesh', India. It ls distlnguished by a moderately developed bursa ln males, a lip region not clearly annulated, and an oval median bulb. T. (Lelenchua) mlrus n.sp. ls described from soli aroun3 the roots of Hlblscus rosaslnensla at Allgarh. It Ts distlnguished by the position of the vulva, slze of the spear and ln the tali length. T. (L.) cynodoneus n.sp. ls described from soli around tfie roots of Cynodon dactylon at Allgarh. It differs from T. (L.) dlscrepans In the absence of males “size"of the spear and length of the tali. Dltylenchus mlnutus n.sp. ls described from soli around the roots of Puniea granatum at Ghazipur, Uttah Pradesh. It differs from D. misellus by the almost stralght body when relaxed and morę posterlorly located vulva. D. cyperl n.sp. ts described from soli around the roots of Cyperus rotundus at Allgarh and It differs from related species malnly ln the position of the vulva, the slze of the spear and ln the shape and length of the tali. D. ausafl n.sp. ls described from soli arouii3 the roots of Rosa sp. at Allgarh and ls characterlzed by a long tali, short bursa and relatlvely anterlor vulva. In the family Hoplolalmidae, Rotylenchus hellcus n.sp. ls described from soli around the roots of Psldlum guająya at Rampur, Uttah Pradesh. It differs from all closely related species except R. orlentalls ln having the orlflce of the dorsal oesophageal gland at morę than half the spear length behlnd the spear base. It ls distlnguished from R. orlentalls ln the slze of the spear, position bf the phasmld and presence of dlstlnct eplptygma ln females. Hemlcycllophora dhlrendrl n.sp. (Hoplolalmidae) ls described from soli around the roots of Cyperus rotundus at Allgarh. It ls characterlzed by the absence of longltudlnal llnes, heolzonld and the tobolar sheath coverlng the splcules, also by the slze of the spear and the splcules, the shape of the tali and In havlng the vulva under a folded sklrt.

The effectiveness of varlous Chemicals ln controlling Dltylenchus dlpsacl ln lucerna was compared. Llquld formułatlons of cynem Ithlonazlml and dlmethoate at 0.5, 1.0 and

2.0    lb. per acre, and Bayer 37289 at the

2.0    lb. ratę, gave good to excellent control of D. dlpsacl. Methyl demeton-R and Bayer 25ft»l gave fair control but were equally effectlve ln suppresslng galllng as were cynem, dlmethoate and Bayer 37289. Both foroulatlons of phorate at all rates. and the granular formulatlon of cynem gave relatlvely poor nematode control but fair supression of galllng. No data on nematode numbers were obtalned for the llquld formu-lation of phorate owlng to the poor control of galllng.
