WOMERSLEY—MICROTROMBIDIINAE OF AUSTRALIA AND NEW GUINEA 32! 
apex, with a subposterior sensillary area at about %4 from apex, sensillae ?, the 
bases 254 apart. Eyes 2-4-2, on well defined ocular shields, well in advance of 
sensillary area. Chelicerae with finely serrate inner edge. Palpi stout, tibia 
with apical claw, smaller accessory claw, two pectines and a short, stout, external 
spine. Legs shorter than body, I 900u, Il 660p, IIL 660n, IV 900p; tarsus I 
216 long by 122 high, Ti/Tw — 1-77, metatarsus I 144» long, Ty/M, — 1:5. 
Dorsal setae of uniform type, mainly stout with long setules and to 20u long; 
on the propodosoma near erista and near the suture, as well as at the posterior 
end of hysterosoma they are somewhat longer, to 25p. 

Fig. 16. Microtrombidium jabanicum Berl. A, Crista and eyes (X 200); B, palp (xX 200); 
C, front tarsus and metatarsus (X 200); D, dorsal setae from dise of hysterosoma (X 860); 
E, dorsal seta from propodosoma near crista (x 860). 
Loc. Four females and three males from damp soil in typhus area, Good- 
enough Is., Aug., 1944 (D.C.S.). 
Remarks. In the dimensions of the front tarsi and metatarsi this species 
is very near to karriensis but differs in that the clothing of the dorsum is very 
much denser, the setae are stouter, the colour of the animal is different and its 
form much broader across the shoulders in proportion to the length. 
It may, possibly, be the same as agilis Canestrini from Finschhafen but the 
brief description of that species does not permit of comparison.
