Average lengtli of legs (first pair) about '11 mm. 

 Average length of legs (second pair) about -10 mm. 

 Average lengtli of legs (third pair) about -12 mm. 

 Average length of legs (fourth pair) about '13 mm. 



A minute, thick-set, and well-marked species. 

 Colour light yellow-brown. 



Texture polished, without any markings or punctures 

 that are visible with say 200 diameters amplification. 

 Shape short-pyriform. 



Cephalothorax long and large, about five-twelfths 

 of the entire length of the creature, forming a trun- 

 cated cone. Rostrum rounded, blunt. Rostral hairs 

 short. Palpi not showing from the dorsal aspect. 

 Lamellae very strong and clearly-marked ridges, almost 

 blade- like ; short and very slightly undulated ; witho^lt 

 cusps but the ends joined by a very strong translamella. 

 Pseudo-stigmata large, placed rather near together. 

 Pseudo-stigmatic organs short, slightly recurved, with 

 thick fusiform heads on short peduncles. I have not 

 been able to detect any interlamellar hairs. There is 

 a short, doubly-curved ridge on each side of the ros- 

 trum, starting from above the insertion of the first leg 

 and terminating a little in front of the lamella ; and a 

 single transverse ridge joining the pseudo-stigmata 

 close to the progaster. Tectopedia small. Apodemata 

 joined to the sternum. 



Legs rather short, joints thick, except the hind tarsi. 

 Femora without blades. Tactile hairs on all tibiae and 

 a few other fine hairs on the respective joints. Claws 

 monodactyle. 



Abdomen short and arched, truncated anteriorly. 

 There are/ottr longitudinal ridges on the anterior part 

 of the notog aster, the central pair of which turn at right 

 angles and run a short distance along the progaster 

 and then return to the notogaster, running parallel to 

 their original course and looking like two shorter 

 extra ridges. There are four sparse rows of short, 

 fine hairs on the notogaster. Genital and anal plates
