180 THE ENTOMOLOGIST. 



ON A NEW GENUS AND SPECIES OF PARASITIC 

 CYNIPID^ (EUCOILIN.E) FROM CAPE COLONY. 



By p. Cameron. 



Stirenc(ela, gen.' nov. 



$ . Antennae fifteen-jointed, the third joint as thick and slightly 

 shorter than the fourth, not incised ; the other joints a little longer 

 and thinner than the third or fourth. Scutellum prominent, roundly 

 gradually raised from the base ; the cup small, broadly ovate, placed 

 on the apical slope above, the lower margin projecting as a rim. 

 Post-scutellum large, projecting roundly above, obliquely sloped 

 inwardly from near the top to the bottom ; the post-scutellum is 

 below the scutellum ; both project over the metanotum. Meso- 

 pleurae margined below ; the apex of the metapleur® broadly 

 margined, the top roundly projecting. Base of pronotum stoutly 

 margined round the top. Radial cellule closed on basal margin, the 

 rest open ; completely separated from costal cellule ; the areolet 

 obsolete, as is also the cubitus ; an oblique nervure runs into the 

 costal close to its base and another near its apex, the latter being 

 bullated and longer than the space between it and the areolet ; the 

 margins are not ciliated, the wings being quite bare ; the apex 

 broadly rounded. Base of abdomen with a broad hair girdle. Malar 

 space distinct, half the length of the eyes. 



The ocelli are prominent and are placed on the margin of the 

 vertex. Parapsidal furrows obsolete. The first abscissa of the radius 

 is rounded and is distinctly shorter than the second, the costal 

 nervure is bullated at its apex. Scutellar foveae large, deep, divided 

 by a distinct keel ; the lateral partition is transparent in the middle. 



Comes nearest to Diranchis, Foer., which may be known from 

 it by the antennae in the male having the first joint of the fiagellum 

 one and a half times longer than the second, the scutellum 

 rugose not smooth and shining, andthe wings pilose with a long 

 ciliated border. 



Stirenccela striaticollis, sp. n. 



Black, shining, the fiagellum of antennae, legs and abdomen 

 bright red ; smooth, except the basal half of the pronotum which is 

 distinctly, closely obliquely striated, wings brownish black to the 

 radius and areolet, clear hyaline beyond ; the nervures black ; the 

 cubitus very faint, almost obsolete. <? . Length 4 mm. Antennae 

 bare, tapering towards the apex, longer by about one-third than the 

 body. The hair on the metathorax sparse, long and white ; the hair 

 girdle of a darker white colour, tinged slightly with fulvous. The 

 mandibles are dark rufous.
