THE PRESENCE OF RING-JOINTS IN AUSTRALIAN 

 SCELIONID^. 



BV .A.LAX I'. DODD, NELSON, N. Q., AUSTKALTA. 



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 ne^•er searched for them, and it was 

 only accidentally that their presence in this species was noticed. 

 This disco\ery 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 y>/ca5/«ff7 

 Gryonella reticulata Dodd; Subfamily Balince, Acolomorpha minuta 

 Dodd; Subfamily ScelionincB, IIadro)iotus >:i«riceps Doikl, Opistha- 

 caiitha airaulti Dodd, Sceliacanthella paroipeniiis Dodd, Lcptoteleia 

 aitrea Dodd, Baryconiis exserttis Dodd, B. loii'^ipennis Dodd, and 

 B. trispinosus Dodd. 



The species, Opislhacantha giraiilti, possessed apparenlK- one 

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

 be three exce.ssively thin ring-joints. Gryonella reticulata had two 

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

 each. This disco\erv is of considerable interest.
