ZONOPTERUS BOSSCHAE. 107 



NOTE III. 



A NEW SPECIES OE THE LONGICORN 

 GENUS ZONOPTERUS 



DESCRIBED BY 



C. RITSEMA Cz. 



It is very closely allied to Zonopterus magnijicus Bates ^) 

 from Mount Kina Balu (North Borneo) and strongly resem- 

 bles that species of which I have a female example from 

 Mr. Oberthür's collection before me. The new species, of 

 which Dr. J. Bosscha captured a female specimen near 

 Sambas (West Borneo) , differs however from magnificus 

 by the narrower and more orange yellow coloured elytral 

 fascia , which moreover is farther removed from the base 

 of the elytra, by the somewhat otherwise coloured an- 

 tennae (the three basal joints and the basal half of the 

 4th joint are black) , by the fulvous anterior tarsi , by the 

 more slender posterior legs and , last not least , by the 

 shape of the apex of the last (5th) ventral segment which 

 is deeply notched in the middle in the female of magni- 

 ficus^ entire however in the same sex of the new species. 



I propose to call the new species, in honour of the 

 captor of the described specimen, 



Zonopterus B osscliae. 



Length from the front margin of the inter-antennary 

 ridge to the apex of the elytra 33^2 i^am., breadth at the
