of ceplialotiliovnx 33 /* ; of abdomen 29 yu, ; of capitulum (at base) 

 22 /x ; length of capitulum 18 ft. 



Host : .Brown Squirrel (Scmrus vulgaris). A specimen of this 

 mite was collected from a squirrel received from Inverness, 

 21. iv. 1922. 



Tausonemus translucens Green. 



This mite has already been recorded as occurring on tea in 

 Ceylon and India, and also described by myself from specimens 

 found on Cajysiciun in Trinidad {F. W. Urich Ooll.). Professor 

 G. S. Kulkarni has brought to the Museum specimens found on 

 potatoes at Poona. He states (Agric. Journ. India, vol. xvii. 

 part 1, Jan. 1922, pp. 51-54) that this mite is the cause of the 

 very serious ^^ Mania" disease of G\\\\\\ {Cai^sicum) and also of 

 the " Tanibera " disease of potatoes in India, 



■ Tarsonemella, subgen. nov. 



Closely allied to Tarsoneimis, but the legs of the first pair 

 stouter than the others and without pulvillus. Also the pseudo- 

 stigma nonniilly i>resent between the first two pairs of legs in 

 Tarsonexius is absent, l^'ourth leg of female modified in a 

 similar way to that of the typical 2\irsonem.us, the terminal 

 segments being attenuated and ending in a long hair. 



Tarsonemus (Tarsonemella) africanus, sp. n. (Texfc-figs. 

 20 & 21.) 



5 . Shape rather elongate-oval, the body being much longer 

 than wide. Tarsus of first leg Avith a well-developed but not 

 very large claw, which is slender, curved, and sharply pointed. 

 Dorso-laterally near the distal end of this tarsus there is a slender, 

 striated cylindrical seta of fair length, and near the middle there 

 are two similar but smaller seta?, one of which is very slightly 

 clavate. Two or three stiff hairs with broken-off ends like those 

 present on the same segment in Pseudotarsonemoldes spiri- 

 tarsus, sp. n.,also occur on the first tarsus. Tarsus of the second 

 leg with a striated seta dorsally of about the same size as the 

 longest one on the first tarsus, and also a shorter and stouter seta 

 on its posterior side. Tarsus of second and third leg with a 

 pulvillus and paired claws. Hairs on body short, especially the 

 ventral ones ; owing to the fact that the specimens of this mite 

 are mounted in balsam, it is difficult to be certain of the exact 

 number and distribution of these hairs. 



Length (including capitulum) 200 /x. 



Host: A hymenopterous insect {Agaon a;ysi?7<?7i Waterston) ; 

 from Koforidua, Gold Coast (4. iv. 1921).
