Hob. Upper Tongaat, Natal {C. Barker). 



Of this species I received a single specimen from Mr. 

 Barker ; tlie broad flavous margin of the thorax and the 

 sculpture of the elytra will at once distinguish it from 

 A. granulosa, which is also of general smaller size. 



Malarosoma , Cliev. 



Although this name has been in use for a genus of 

 Gahrucinx ever since 1846, it is high time to change it, 

 since it has long before that time been employed by 

 Hiibner for a gemis of Lepidoptera. I am therefore 

 reluctantly obliged to change it to Exosoma. 



Exosoma larhcri, sp. n. 



Under-side black or piceous, upper-side flavous, thorax trans- 

 versely subquadrate, im^^unctate. elytra microscopically punctured.

 carina acutely raised, labrum and palpi flavous, antennae in the male 

 long and slender, extending beyond the middle of the elytra, flavous, 

 the terminal joints slightly darkened, third joint twice as long as the 

 second one, fourth joint distinctly longer than the third ; thorax 

 about one-half broader than long, of equal width, the sides rounded 

 at the middle, the anterior angles thickened but not produced, tlie 

 disc rather convex, not perceptibly punctured, scutellum triangular, 

 flavous, elytra slightly wider at the l^ase than the thorax, closely
