.364 PARASITIC HYMENOPTRHA FROM THE SOLOMONS, 



tinged with red. Wings clear hyaline, stigma fuscous, ner- 

 vures black, areolet oblique, nervures uniting in front ; recur- 

 rent nervure received at apex of areolet, interstitial with 

 second transverse cubital ; transverse median behind trans- 

 verse basal. Length, "9 ; terebra, 4 mm. 



The outer margins of the central part of the face are 

 roundly curved outwardly, the middle is finely keeled. The 

 furrows of the mesonotum are united into one at the base of 

 the apical third ; they are smooth. Lower third of pro- 

 pleurae finely, obliquely striated ; apex of mesopleurae crenu- 

 lated. The middle of the metanotum is slightly raised, form- 

 ing almost an area of equal width, shining, almost smooth ; 

 the rest is somewhat strongly and closely transversely stri- 

 ated, at the base the striae being finer and more oblique. 

 Metapleurae irregularly shagreened. Abdomen smooth and 

 shining • first segment nearly as long as the following two 

 united. Mesosternum reddish. Tooth on hind femora 

 small but distinct, oblique. Palpi pallid testaceous. 



The affinities of this species are with L. rufipes Cam., from 

 Ceylon, rather than with any known Australian species ; it is 

 more slenderly built, especially as regards the abdomen, 

 which wants the coloured bands of L. rufipes; and the 

 scutellum, metanotum, and pleuise the white spots. In my 

 figure of L. rufipes (Spolia Zeylanica, iii., p. 140, PI. B), the 

 transverse median nervure in the hind wings is shown broken 

 too low down ; it is a characteristic of Lissopimpla that it is 

 broken near the top. 



« Xanthocryptus luteus, sp.n. 



$. Ferruginous; head and antennae tinged with yellow, 

 the eight or nine apical joints of antennae black, as is also the 

 apex of mandibles ; wings hyaline, tinged with fulvous, apex 

 with a smoky border, costa and stigma testaceous, nervures 

 black; base of metanotum in centre finely, irregularly longi- 

 tudinally striated; the rest, from the keel, much more 

 strongly, and more widely transversely striated ; metapleurae
