G. hella ; it is also present in G. annidata^ according to Baron 

 Osten-Sacken. The 9 ovipositor is broad at the base, the upper 

 valves long, carved, and the lower ones shorter and straight. 



The venation is not subject to very great variation. The 

 auxiliary vein joins the costa more or less opposite the inner end 

 of the second sub-marginal cell, rarely opposite that of first sub- 

 marginal ; the sub-costal cross-vein is close by its tip. The first 

 longitudinal vein joins the costa usually a little beyond the middle 

 of the anterior branch of second longitudinal vein ; the marginal 

 cross-vein situated about its length distant from the tip of the first 

 longitudinal vein is usually opposite the middle of the anterior 

 branch of the second. The prsefurca is moderately long, more or 

 less arcuated at its base. Second sub-marginal cell slightly longer 

 than the first, the petiole of the latter more or less the length of 

 marginal cross-vein ; the anterior branch of second longitudinal 

 vein arcuated at its base, then curved gently upwards, and about 

 twice the length of posterior branch which is gently curved down- 

 wards. Inner ends of second sub-marginal and discal cells usually 

 opposite one another ; the small cross-vein a short distance beyond ; 

 in G.flavipennis the small cross-vein is extremely small or entirely 

 obsolete so that the inner ends of the second sub-marginal and 

 discal cells form almost a right angle with one another. There 

 are five posterior cells in all but one species, G. jucunda, O.-Sacken. 

 The second posterior cell in the former case, varies from one-half 

 to two-thirds the length of the third posterior; the third and 

 fourth posterior cells of equal length or the latter somewhat longer. 

 Discal cell closed, usually not more than twice longer than broad ; 

 the great cross-vein usually about opposite its middle, but near 

 its inner end in G. flavipennis. Sixth longitudinal vein slightly 

 and seventh distinctly sinuated. The wings (PI. xxiii., figs. 30- 

 42) more or less completely banded transversely with brown ; 

 except for stigma they are immaculate in G. flavipennis, 



Schiner's Gloniophora and Thomson's Cmnarthria are Gynoplistice; 

 the difi^erence in the antennse being only of specific importance. 

 The species which seem to diff'er most from the rest are G. vilis, 

 Walk., and the extra- Australian G, jucunda^ O.-Sack.
