spot beyond radial area, piceous or black ; the brown colora- 

 tion also contains some paler spots; on the outer hyaline 

 area there is a waved spot commencing at costa and crossing 

 bases of first to fourth apical areas, some submarginal spots, 

 a small spot on each side of the apices of longitudinal veins 

 to apical areas, followed by a larger spot on ext\-eme outer 

 margin, piceous or black ; wings black, their outer fourth 

 pale hyaline. 



Head (including eyes) about two thirds the width of base 

 of mesonotura ; rostrum reaching base of abdomen, its apex 

 black; opercula broadly transverse, their inner angles over- 

 lapping, their outer and lateral margins moderately convex.

This species has a strong superficial resemblance to a very 

 large example of Platy pleura nohilis, Fabr., but belongs to 

 the genus Pycna by the relative breadths of the head (in- 

 cluding eyes) and the base of mesonoturai.

Allied in general coloration to U. Stalina^ But!., less so to 

 U. grandicollis, Germ., from both of which it differs by the 

 much longer and more acute lateral pronotal angles, the 

 broader central sulcation to face, the opercula in male only 

 nearly meeting, and not overlapping internally as in 

 U. Stah'na ; rostrum reaching but not passing the posterior 

 coxaj. By the shape of the pronotum it is more allied to 

 U. limhata, Fabr., from which it differs by the pale casta- 

 neous wings, more sharply angulated lateral angles of pro- 

 notum, broader longitudinal sulcation to face.

XLVIL — On a Pneuniatic Type of Vertebra from the Lower 

 Karroo Rocks of Cape Colons/ (Tamboeria Maraisi). By

In August 1889 I found at Tamboer Fontein, between 

 Fraserburg Road Station and Fraserburg, an isolated vertebra, 

 loose upon the surface, which differs in type from all reptiles
