Dactylopiince. 363 



the two pairs being situated near the anterior and posterior extremities respec- 

 tively. Anal aperture surrounded by six stout setae. Length approximately 

 o"5o mm. 



Eggs {fig. 3) white. 



Habitat : In the soil, attached to roots of grasses and other plants, under 

 stones ; and in the thin layer of soil and dwarf herbage covering rocks ; 

 Pundaluoya and Kandy. 



Occurs also in the Hawaiian Islands, where it has been observed by 

 Mr. J. Kolinsky. 



Genus PSEUDANTONINA, nov. 



Species resembling Antonina in habit and form, but possessing limbs. Type, 

 bambustz. 



It will be inadvisable to fix the characters of the genus too closely, pend- 

 ing the discovery of other species. The characters of the single species for 

 which the new genus has been erected appear to be intermediate between those 

 of Antonina and Ripersia. 



PSEUDANTONINA BAMBUS^, nov.' 

 (Plate CXLIII.) 



Adult female {fig. i) naked or sparsely covered with loose white secretion ; 

 irregularly elongate oval, evenly rounded at either extremity ; flattened by 

 compression from its position between the stem and the enfolding stipules. 

 Antennje marginal, very small ; usually five-jointed {fig. 2), occasionally with 

 six {fig. 3), and sometimes with only three joints {fig. 4) ; intersegmental 

 divisions feeble and frequently indistinct. Limbs very small and weak, though 

 the normal number of joints are developed and even well formed {fig. 5) ; claw 

 long and slender, curved at the tip ; tarsal digitules long and slender, minutely 

 knobbed : ungual digitules rather shorter. The median and posterior legs 

 appear to spring from a crowded patch of minute pores, but these pores are 

 actually on the dorsum, immediately above the insertion of the limbs (see 

 {fig. 5). Rostrum situated close to the anterior extremity ; mentum broad and 

 short. Spiracles rather small, opening into a short cylindrical chamber. Anal 

 orifice {fig. 6) opening on to or just within the posterior margin. Anal ring 

 incomplete, bearing six moderately long setae. Derm with a few very small 

 scattered spiny hairs, and circular pores of various sizes, viz., a series of com- 

 paratively large thick-rimmed pores {fig. 2) on the anterior margin, extending 

 downwards on each side to the level of the anterior spiracles {see fig. i) ; some 

 smaller pores on the marginal area of the abdomen, more crowded on the posterior 

 segments {fig. 6) ; crowded patches of still smaller pores above the insertion
