4. Fifteenth Species of Gonatocerus from Australia. 



Genus Gonatocerus, Nees. 



Gonatocerus ayrensis, n. sp. (normal position). 



FcwiaZc— Length, 1-15 mm. Slender. Golden yellow, the head 

 dusky black, the tip of abdomen and a narrow transverse band before 

 it, black ; funicle and club black, the pedicel suffused somewhat with 

 dusky ; middles of posterior femora and tibiae black. Antennas 

 characteristic — all funicle joints long, except the first and last ; the 

 first is only two-thirds the length of the second, which is slender and 

 subequal to the pedicel; the distal funicle joint is only half the 

 length of the joint preceding it, which is somewhat the longest joint 

 of the funicle, subequal to funicle joint 5 and half the length of the 

 long club ; the distal joint is oval. Scape long. 



Agrees with bacom, and may be the female of that species, but 

 the cephalic two pairs of legs are lighter in ayrcnsis, there is no 

 noticeable black on the thorax, and the proximal tarsal joints are 

 longer. Also in ayrensis the scape is much longer than in baconi, 

 but in some species of the genus this is a secondary sexual character.
