The American Anthribidac allied to the Old World genera Nessinra, 

 Straboscojjus, Jbjlopetnon and Apatenia diff'er from the Old World species in 

 the ai>ical marginal strij) of the metasternum in front of the coxa not meeting 

 the corresiionding piece of the other side, the apical mesial sinus penetrating 

 to the sternal jilate of the metasternum in the New World species, while ir 

 does not extend so far in the Old World species. This gronji of oblique-eyed 

 Anthribids appears to be very numerously ropresentetl ia America, where true 

 Acori/ /!"■■<, /./fuci'i'K.H and 'I'ropideres do not occur.
