 Xaturj'. Freunde Bfirlin p. 242, very variable in shape accordiiiir to the size of the 

 individuals ; iu the large specimens the frontal horn is broadly dilated at end, its 

 upper edge broadly convex, the very middle feebly sinuate, the sides produced distad 

 into a jirominent tooth ; in small individuals the horn is short, slightly dilated 

 apically, truncate with the distal edge very feebly bisinuate, its upper surface black 

 or brown, opaque ; the occipital horn is bifurcate, the branches projecting laterad 

 and curving frontad, iu small examples the branches are very short and obtuse. 

 Pronotum strongly convex, almost globose ; in small individuals, however, less 

 convex, resembling more the pronotum of the S . Fringe of pygidium ochraceons, 

 that of mid- and hindtibia paler, sterna with grey hairs ; episterna above and sides 

 of abdomen close to elytra pilose, edge of elytra with a buffish fringe. Foretibia 

 broad, inner edge dilated from near base to middle, the dilated part proximally and 

 distally produced into a tooth, then comes a deep sinus followed by a prominent, 

 triangular, apical tooth, the outer edge is armed with equidistant teeth in apical 

 half : mid- and hindtibia with two teeth in and before middle, iu small individuals 

 with one tooth in middle. 



?. In colour like the S- t'lypeus truncate, with the angles slightly rounded, 

 edges raised, the ridge of the lateral edge continued to occiput, curving mesiad 

 posteriorly, where it gradually disappears ; middle of head convex, tlie callosity not 

 j)rominent, anteriorly gradually vanishing, sides of the ante-ocular part of the head 

 laterally of the ridge rounded. Pronotum with dispersed i)uncturcs, anterior edge 

 feebly bisinuate, sides marginate, in posterior half faintly sinuate. Scutcllum and 

 elytra smooth, the latter with few feebly impressed punctures laterally. Intracoxal 

 process of mesosternum rounded as in S. Foretibia without internal teeth, with

H'tb. Escarpment, British E. Africa, OoOU — 900U ft., September to April 

 19011-1 (W. Doherty). 



There was a series of this pretty beetle in the small collection of (Joleoptera 

 which we received, together with the other insects after W. Doherty's death. 

 1 name it in memory of our lamented friend. These L'oleoptera (except the 

 Ceramhyridae and the few Anthrihidae), are now in the collection of Mons. Rend 

 Oberthiir, inclusive of the tyjie of St. dohcrti/i.
