than the lower and acute, the lower small ; mentum oblong, the 

 outer median part setose, the anterior margin little sinuate. Pro- 

 thorax hexagonal with the sides angularly produced in the middle. 

 Anterior tibiae bi-dentate. Metasternum with a straight obtuse 

 mucro between the intermediate coxae. Elytra strongly emarginate 

 behind the shoulders, each one with a raised longitudinal, little 

 curved keel reaching from the sides of the scutellum to the apical 

 tubercle. Abdomen not depressed underneath towards the base ; 

 apical spiracles conical ; pygidium carinate in the middle and 

 tuberculate on each side. 



This genus is proposed for an African species which agrees with 

 Macroma in its general details, but differs from the species of that 

 genus in its small size, hexagonal prothorax, and colouring." 



Macbomina angulicollis, Westw., 

 Loc. cit., p. 15, pi. vii., fig. 3. 



Oblong, sub-depressed on the upper side, shiny, punctate ; clypeus 

 somewhat rounded, anterior margin raised ; sides of protborax 

 prominently angulate in the centre, posterior margin slightly broader 

 than the anterior one, nearly straight, median part of the disk with a 

 very fine keel ; shoulders of elytra raised, suture depressed towards 

 the base but raised towards the apex. Black, prothorax with a 

 median narrow dorsal bloody-red line, and the sides also narrowly 

 sanguineous, this lateral band enclosing a black ante-median dot ; 

 scutellum and two narrow lines in each elytron bloody-red, these 

 lines are united before the apex by a transverse striole ; elytra 

 punctate and having a very fine line close to the suture and running 

 parallel with it, sides with transverse strioles. 



The only example of this interesting little species which I have 

 hitherto seen I obtained from a Collection received from Lake N'Gami ; 

 it is a male, having the basal segments of the abdomen longitudinally 

 impressed down the middle. The two terminal spiracles of the 

 abdomen are prominent, and the pygidium is raised so as to form 

 three obtuse tubercles. 



Length 12 mm. ; width r>\ mm.

centre with the outer angles slightly rounded, angular laterally
