In a former communication to the Society, I mentioned the 
affinity of this insect with Mesotopus Tarandus: subsequent inves- 
tigation, however, leads me to place it near Cladognathus, and to 
refer it more particularly to the African species C. faber, C. Na- 
talensis and C. modestus. It resembles these in having the head 
broad and armed behind the eyes; the mandibles slender and 
faleate; the legs likewise slender; the anterior tibize of the 
females slightly curved and not dilated as in Mesotopus, and the 
posterior tibize 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.
