SIHYNES Schonherr. 



A (ienns almost exclusively confined t(t the Old World, l»ut of whicli a 

 single species is known from ("alifornia. Oustalet has described a fossil 

 sjjecies from Aix, and one, which, however, bears no sp(H-ial resem])lance to 

 that, has been found at Florissant. It differs slightly in antennal structure 

 from the living forms; as in these, the funicle is six-jointed, ])ut the relation 

 of the joints is a little different: the first joint is the longest, the second is 

 somewhat shorter, nnich slenderer, expanding apically, twice as long as its 

 apical breadth, and more than twice as long as the tliinl joint; followiuf 

 the second are three precisely similar (juadrate joints, scarcely broader than 

 loug, followed by a similar but a little broader sixth joint.
