654 PARASITIC HYMENOPTERA, ii., 



dered by a keel. First abdominal segment campanulate, 

 longer than wide, the nai'rowed end at the base ; second the 

 longest, longer than the following united, the segments 

 becoming gradually widened to the penultimate, the whole 

 being shorter than the thorax. Fore- femora greatly swollen, 

 straight on the lower, roundly, broadly narrowed on the 

 upper side ; base in front slightly depressed in the middle, 

 middle femora more slender than the hinder, as are the 

 middle tibiae than the posterior. Second joint (pedicle) of 

 the antennae about twice longer than wide, third double its 

 length, fourth about one-quarter shorter, the others shorter, 

 fifth and sixth twice longer than wide, the others wider than 

 long. Parapsidal furrows almost obsolete. 



This genus fits in best into the Cleonymina', and probably 

 is most nearly related to Heydenia, a genus which appears to 

 be very little known. It is stated by Foerster to resemble 

 one of the Bryinoidfp, which is certainly the case with the 

 present genus. In Heydenia, the parapsidal furrows are indi- 

 cated ; there are no keels on the metanotum nor clouds on 

 the wings. 



Paraheydenia longicollis, sp.n. 



Upper part of head and thorax brassy-golden, sutures 

 blue ; pleurae similarly coloured, but more largely tinged with 

 blue, especially below ; abdomen dark purple, the base blue, 

 the middle laterally tinged with golden-brassy ; legs dark red, 

 four hinder coxse purple, tarsi testaceous, basal Joint white ; 

 antennal scape red, pedicle brassy, the other joints black ; 

 wings hyaline, nei'vures black, an oval fuscous cloud at the 

 stigma. (J. Length, 4 mm. 



Wagga, N.S.W. ; in April (W. W. Froggatt). 



Antennal furrows wide, converging and uniting above, dark 

 green, closely reticulated-pimctiired, as is also the vertex ; 

 the rest of the head more finely punctured. Ocelli in an 

 equilateral triangle, the hinder separated from each other
