Lamellae very low, almost parallel ridges, with sharp and even, slightly 

 raised exterior edge from which their surface slopes gently downwards towards 

 the median edge which is irregularly wavy and not always clearly defined. 

 Between the proximal ends of the lamellae there is an elongated, oval depres- 

 sion. The interlamellar hairs are inserted a little in front of the pseudostig- 

 mal organs, almost perpendicular, straight and fairly stout, almost half as long 

 as the lamellae. In front of the lamellae there are numerous linear wrinkles of 

 the cuticle which together form an even curve, connecting the anterior ends 

 of the lamellae. In the anterolateral angles of this curve the lamellar hairs are
