Legs uormal; legs IV crooked, turned inward, apparently 

 holding or clasping.

(With Plate 12, fig. 39-51). 



1904. Nov. 1. Pterolichus asiaticus nov. sp. Oudemans in 

 Entom. Bericht., No. 20, p. 194. 



Protonympha (Fig. 39). Length 370-420 /«. Co- 

 lour straw coloured. Shape the usual one, elongate, widest 

 between legs II and III, rounded posteriorly, a little constricted 

 at the level of legs IV. Noticeable are 4 small square lobes 

 flanking the abdominal incision. Texture smooth on the 

 shields ; soft skin very roughly wrinkled. 



Dorsal side (Fig. 39). Anterior dorsal shield 

 very short, reaching not further back than the line which 

 goes trough the centres of trochanteres I, nearly one and a 

 half time longer than wide, posteriorly well rounded. No posterior 

 shield, if not the uu wrinkled abdominal lobes represent such. 

 8 kin very roughly wrinkled, roughest posteriorly. The wrinkles 

 in the fore-half of the body for the greater part transverse, 

 in the hind-half longitudinal ones. The lines in which these 

 two systems of wrinkles touch each other run from the widest 

 part of the body between legs II aid III to a median point 

 on the level of trochanter IV ; these lines are moreover a 

 little convex forward or medianward. Striking is the fact t ha 

 the transverse folds are broken in the medianline, so that 

 they form a distinct median r h a p h e. Hairs: Behind 

 the anterior shield and on a line with the proximal end of 

 trochanteres II stand the pair of long prosomatic hairs. These
