In a former communication to the Society, I mentioned the 

 affinity of tiiis insect with Mesotopus Tarandus : subsequent inves- 

 tigation, however, leads me to place it near Cladognnthus, and to 

 refer it more particularly to the iVfrican species C.faber, C.Na- 

 ialensis and C. modeslus. It resembles these in having the head 

 broad and armed behind the eyes ; the mandibles slender and 

 falcate; the legs likewise slender; the anterior tibiae of the 

 females slightly curved and not dilated as in Mesotopus, and the 

 posterior tibiae of the males unarmed. 



Nevertheless, the wide and strongly produced emarginate 

 clypeus, the short, broad form and polished fulvous colour of the 

 elytra, as well as the sinuated character of the sides of the pro- 

 thorax in both sexes, amply justify the creation of the genus pro- 

 posed, which may be placed after Cladognathus, 



This new and interesting insect was kindly presented to me by 

 Mrs. Melly, and was unique in the magnificent collection of the 

 late Andrew Melly, Esq., of Liverpool, to whose memory I have 

 dedicated it. Another specimen has recently been received by 

 Andrew Murray, Esq., from Old Calabar.
