tudinal ridges. On the exterior side of the pseudostigmata there is a small so- 

 called exostigmal hair. 



The pseudostigmal organs are attached near the anterior part of the 

 bottom of the trumpet and protrude close to the anterior wall of the tube. 

 They widen gradually towards the blunt end where there are some rather in- 

 distinct teeth and the pedicel is slightly S-shaped.

slightly pointed posteriorly, where two small terminal hairs are inserted on a 

 wart-like projection. The dorsal side has a median, narrow, elongated oval 

 depression near the anterior margin, and two slightly raised ridges running 

 paralell to the sides in the anterior third. In the centre there is an oval area, 

 almost half as long as the dorsal shield, where there is no special texture, but 

 in the posterior third there are faint traces of narrow dark bands or low ridges 

 running backwards and outwards in even curves and along the sides in the 

 middle, and further forwards other similar ridges running toward the periphery 

 and curved forwards. 



The one larval and three nymphal shields are of the shape typical for
