116 COLLEMBOLA FROM NOHTHERN SARAWAK. 



Remarks. Borner's observations on Pseudosira nyassica of 

 "IV mit Sinneskolben, Kopf, Mesonotnm and die meisten 

 Eiickentheile mit Keiilenborsten" and of "I : II : III : TV =^ 

 1 : 1§ : 2 : 2 — •22y'q" of the antennal formula agree well with 

 my own. Undoubtedly also Imm's Ps. indra and Handschin's 

 newly mentioned Ps. dovw^tica (Nic.) C. B. are good species 

 of this genus. Probably also Wahlgren's LepidocyrUis species 

 of the group "Falciformes" (except perhaps L. traegaardhi) 

 belong here. Wahlgren points out that all "Falciformes" 

 are richly covered with hairs, but says nothing in this respect 

 about his only new species of the group "Bidenticulati." 



Probably also Schaflfer's Lepidocyrtns falcifer and my own 

 Lcp. schafferi ought to be placed here, but decidedly not 

 Schaffer's Sira variahilis as Borner suggests, and furthermore 

 Hitter's both Pseudosira species. 



Lbpidosira n. g. 



More or less Sira-like in appearance with jointed tibiae and 

 retractile terminal organ on Ant. IV. Scales of varying types 

 but generally pointed, with long internal distinct striation. 

 Both manubrium and dentes covered by scales. Body richly 

 hairy. Mucrones bidentate, with basal spine. 



6. LePIDOSIBA MONTANA n. Sp. 



Diagnosis. Ant. 1=1:0.40. 



Ant. I: II: III: IV=1: 1.5: 1.5: 2.2. 

 Abd. Ill: IV=1 : 4.62. 

 Manubr : Mucrodens=l: 1.28. 



Mesonotum not protruding above the hind margin of the 

 head. Eyes 8 + 8, normally placed. Ant. Ill consisting of 

 two curved staffs within wavy skin-folds. Claws with three 

 internal teeth, the proximal one double ; pseudom^chia distinct, 

 reaching to the proximal double-teeth. The empodial appen- 

 dix obliquely cut off, the ventral lamella extremely thin and 

 distinctly serrated. The tibio-tarsal sensitive setae compara- 

 tively short and incrassated towards the apex. Immediately 

 behind this there is an extremely long feather-shaped seta 

 protruding. On the ventral side of the tibiae and amongst the 

 serrated setae a single, j)ointed, simple and uncoloured seta 

 directed obliquely forwards. The scales as a rule of the
