A series of specimens was collected between 1892 and 

 1895 and presented to the British Museum by Mr. W. A. 

 Nutt. 



The colour is a very deep shining chestnut and tlie 

 form narrow and parallel-sided. The horn of a well- 

 developed male is longer than in any other species of 

 Pycnoscliema known to me and very slender and strongly 

 curved. The female has a short sharply-pointed horn and 

 not, as in many of the species, a cuspcd carina. In the 

 type {$) the dorsal carina of the thorax is produced and 

 emarginate in the middle, overhanging the anterior cavity, 

 but in a smaller male it is quite feeble. The propygidium 

 of the female is finely granulated and densely pubescent, 

 but that of the male is quite bare, with two finely and 

 transversely striated bands in the median part,
