10 ZONOPTERUS CONSANGUINEÜS. 



NOTE III. 



ON A NEW SPECIES OF THE LONGICORN GENUS 

 ZONOPTERUS, HOPE. 



C. RITSEMA Cz. 



Zonopterus consanguineus, nov. spec. Q. 



This species, of which I have three female specimens 

 before me, is most nearly allied to and strongly resem- 

 bles the type of the genus : Zonopterus fiavitarsis Hope - 1 ). 

 It is of the same size and general form , but the sides of 

 the prothorax , which are distinctly bisinuate 'm fiavitarsis, 

 are more regularly rounded in the new species. The lat- 

 ter has moreover a narrower scutellum which is hollowed 

 along the middle and has raised sides, whereas the sculp- 

 ture by which it is covered is much less dense, even al- 

 most absent at the base. The femora, which are coarsely 

 punctured in fiavitarsis, have a much finer punctuation in 

 the new species. 



But besides by these structural characteristics the two 

 species may be at once separated by the different distri- 

 bution of the colours on the antennae: in fiavitarsis the 

 four basal joints and a spot at the base of the fifth , in 

 the new species, however, the six basal joints are black. 

 Moreover the first yellow band of the elytra is decidedly 

 narrower in the new species than in fiavitarsis.
