THE PRESENCE OF RING-JOINTS IN AUSTRALIAN 



SCELIONIDM. 



BY ALAN P. DODD, NELSON, N. Q., AUSTRALIA. 



Quite recently while examining the antennae of a Scelionid, 

 Gryonella reticulata Dodd, I was somewhat surprised to find that 

 two small ring-joints were present. As ring-joints have not been 

 recorded in this family, I had never searched for them, and it was 

 only accidentally that their presence in this species was noticed. 

 This discovery caused me to examine the antennae of numerous 

 Scelionids in my collection. I found that in some cases there were 

 obviously no ring-joints present; in others there appeared to be 

 minute ring-joints, but I could not make sure of the fact, while in 

 a few cases the ring-joints were distinct, though small. The 

 following species possesssed obvious ring-joints: Subfamily Teleasince, 

 Gryonella reticulata Dodd; Subfamily Balince, Acolomorpha minuta 

 Dodd; Subfamily Scelionince, Hadronotus nigriceps Dodd, Opistha- 

 cantlia giraulti Dodd, Sceliacanthella paroipennis Dodd, Lcptoteleia 

 aurea Dodd, Baryconus exsertus Dodd, B. longipennis Dodd, and 

 B. trispinosus Dodd. 



The species, Opisthacantha giraulti, possessed apparently one 

 ring-joint, but under high-power magnification there appeared to 

 be three excessively thin ring-joints. Gryonella reticulata had two 

 ring-joints, while the other species mentioned possessed but one 

 each. This discovery is of considerable interest.
