 Pimplini. 



Rhyssa tuberculicollis, sp.n. 



Yellow tinged with fulvous ; basal abdominal segment ex- 

 cept narrowly at apex, the sides of the other dorsal, the apical 

 broadly and the apical ventral, white, fiagellum of antennae, 

 upperside of scape, stemniaticum : a mark in centre of occiput, 

 broad and rounded above, narrowed below, with the sides 

 roundly incised, a small, broad transverse mark on the apex 

 of pronotum in centre, a slightly larger round spot in centre 

 of basal half of mesonotum, a mark in the scutellar depres- 

 sion, narrowed at base, claws and apical joint of hind tarsi, 

 with the whole of the ovipositor, black : second to fourth 

 joints of hinder tarsi fuscous ; wings hyaline, nervures and 

 stigma black, areolet oblique, triangular, the nervures meet- 

 ing in front, second transverse cubital nervure clearly longer 

 than first, recurrent nervure interstitial : it is dilated back- 

 wards and angled shortly above : both branches are straight, 

 oblique : disco-cubital nervure with a distinct stump of a ner- 

 vure. The pronotum laterally becomes gradually widened 

 from the base to the base of the apical fourth, then obliquely nar- 

 rowed, so that a triangular tubercle is formed. Gastracoeli sliallow, 

 the base finely striated, the rest fulvou.s, and there is a fulvous 

 small round mark on the sides at the apex: the fourth and fifth 

 segments have a fulvous mark, in the centre of the apical half, 

 the sixth and seventh have broad fulvous lines, dilated at the 

 apex, down the middle, that on the seventh the larger, and 

 almost triangular.
