2. Aneuryphymus rhodesianus, sp. n. 

 (Plate I, fig. 18.) 



cj. Very much like xi. eri/thropus, but differing from it in the 

 following charactci-s : Shorter and broader, distinctly more rugose. 

 Pronotum shorter, with the hind angle obtuse, rounded. Elytra 

 scarcely reaching the hind knees. The last abdominal segment 

 with an obtuse angular emargination and a small black tooth in 

 the middle of the hind margin. SujDra-anal plate Avith only one 

 submedian pair of tubercles and another pair at the basal angles. 

 Cerci about twice as long as they are broad, with two obtuse teeth 

 on the lower margin, with the ape:^ obtuse. Coloration of the 

 same general type as in ^. erythropus, but the elytra with smaller, 

 scattered brownish spots, and the inner side of the hind femora 

 red, only partly blackened along the upper carma. 



$ (paratype). Differs from A. eri/thropus in the same general 

 characters as the male, and, besides, in the deei:>er and more narrow 

 emarginated subgenital jslate, the apex of which is acutangular. 



Tyjje and 'paratyjje are in the Hope Department, 

 University Museum, Oxford ; they were both captured by 

 Dr. G. A. K. Marshall, at Mahakata River, Gazaland, 

 S.E. Ehodesia, about 5000 ft., 24 ix. 1905. 



This new species is not yet represented in the British 

 Museum, where, however, there is one more, probably 

 und escribed, species from Barberton, which I abstain from 

 describing from a single rather unsatisfactorily preserved 

 male.
