genus. Length 1:05 mm., width 0-6 mm. Legs shorter than the body, T 855,, ET 
D40p, LIT 540y, TY 750%, tarsus I broadly elliptical with ventrobasal shouder, 
151p long by 100p high, metatarsus I 90 long. Crista linear, 218», long, with 
subposterior sensillary area with paired filamentous sensillae, their bases 20p

spine; tarsus elongate, reaching to about tip of claw. Dorsal setae of two sizes 
as in fig. 12 D, more or less fusiform, with only moderately long setules, shorter 
setae 16% long, longer setae to 32» long. 
Loc. Twospecimens in soil, Dobodura area, New Guinea, about July, 1944 (G. 
M. Kohls). Four other specimens from Goodenough Is., Ang., 1944 (D.C.8.) in 
damp sou in typhus area, do not differ in the dorsal setae, although the dimen- 
sions of the front tarsi and metatarsi ate somewhat variable, as given in the fol- 
lowing key to species.

to 25mm, width to1-8mm. Legs shorter than body, 1 1500p, IT 1050p, ITT 1000u, 
IV 1445,, tarsus I more or less parallel sided and elongate, 405p, long by 120, high, 
metatarsus 2404 long. Crista linear, 890p long, with subposterior sensillary area 
with paired filamentous sensillae with their bases 40 apart (ef. fig. 12 EB). Ryes 
2++-2, fairly large and on well chitinized oevlar shields. Mandibles with chelae 
finely serrate on inner edge. Palpi stont, tibia normal with stont accessory claw,

This specios was originally deseribed by Canecatrini from Erima, New Guinea, 
I have recently received specimens of what I take to be Canestrini’s species from 
Dobhodnra area, New Guinea and collected in soil by Maj. G. M. Kohls. Further 
1 now find that the specimens from Malanda, Queensland, previously recorded 
by me as hystricinum (loc. cit.) are eo-xpecific with those received from New 
Guinea. 
Canestrini speaks of some of the longer dorsal setae as being ‘‘biforcate’’ 
and in the specimens now referred to his species some of these seta, although
