144 A. C. OUDEMANS. ACARI. 



Patria : New Guinea, Tamur, 6 Aug. 1903. 

 Fourni by Messrs. de Beaufort and Lorentz. 



Maie (Fig. 94 — 102). Length 320 — 424//.. Colour white with scarcely rose rostrum and 

 legs. Shape of abdomen more or less sack-shaped, viz. anteriorly truncated, posteriorly roun- 

 ded, with slightly convex sides, sometimes a little constricted in the middle ; céphalothorax 

 more or less triangular. Fore legs slightly thicker than the hind legs, of which again the fourth 

 is the thicker. Fourth legs when stretched backward not extending beyond the abdomen. First 

 legs only extending beyond the rostrum with the tarsus. Texture smooth. 



Dorsal side (Figg. 94, 95). Démarcation of céphalothorax and abdomen distinct, convex 

 forward. Vertical hairs close together, yet their basai rings do not touch each other. On a 

 level with thèse hairs another pair, placed exactly on the edges, is pressed nearly against 

 the rostrum. On a level with the proximal end of trochanteres I a transverse row of 4 hairs, 

 of which the inner pair stands a little behind the outer one ; the outer pair as long as half 

 the length of the céphalothorax, the inner one as long as the céphalothorax. A little behind 

 the démarcation of céphalothorax and abdomen there is a row of 6 hairs. The inner pair is 

 very short, extending scarcely beyond the démarcation when stretched forward. The shoulder- 

 hairs are as long as the width of the abdomen. A third pair exactly on the edge is scarcely 

 shorter. On a level with the femora III a submedian pair of hairs as long as half the width 

 of the abdomen. A little more backward a submarginal pair of very short and quite stiff 

 hairs. On a level with the distal end of femora IV a pair of hairs longer than the width of 

 the abdomen, and placed on equal distance from the médian line and the latéral edge of 

 the abdomen. (In another maie of the same lot (Fig. 94) thèse hairs are much longer, as long 

 as the abdomen). Along the rounded posterior edge of the abdomen four marginal hairs, of which 

 the outer pair the shorter, the inner pair as long as the abdomen. Exactly on the posterior edge 

 again four hairs, of which the inner pair submedian and longer than the abdomen; the outer 

 one slightly shorter. Ail thèse hairs are haired, provided ail around with minute hairs. (Fig. -98), 

 not so densely clothed with them, however, as in Glycyphagus. Ail the hairs are planted on 

 minute warts. The openïngs of the nephridia are submarginal, on a level with the middle 

 of genu IV. In the dorsal arm-pit of legs I there is a split-shaped pseudostigma. The 

 pseudostigmatic hair (Fig. 99) proximally spool-shaped and feathered, the distal half smooth, 

 setiform. 



Ventral side (Fig. 96). Epimera I joined to a sternum. Epimera II curve, free. Behind 

 the coxal portion II we find an epimerite, resembling epimeron II, but slightly longer, curve 

 and proximally touching the ventral transverse groove. Epimera III short, straight, proxim- 

 ally and distally slightly nodded, with a tendence to become transversely placed. Epimera 

 IV like epimera III, but longer and making 45 with the médian line. Génital aperture bet- 

 ween epimera and coxae IV ' , shut by two valves, under which the 4 génital suckers, short 

 and club-shaped, are discernible. Anal split, shut by two valves, long, placed on equal dis- 

 tances from the génital aperture and the posterior edge of the abdomen. Anal suckers aside 

 of the posterior end of the anal split, remote from each other their own diameter. Behind 

 the anal suckers and a little outward two problematic light refracting points. Ail the hairs 

 of the ventral side and before the anus are fine and smooth, those behind the anus are haired. 

 On the coxal parts I (scarcely to be called plates) a hair, longer than epimera I. Before
