ICHNEUMON. 143 



Head and thorax coarsely punctured, opaque or semiopaque, covered with a close 

 pubescence. Head much excavated above the antennae, face not much projecting, apices 

 of mandibles ferruginous. Scutellum scarcely raised above the mesonotum, the sides 

 indistinctly bordered. Metathoracic areas distinctly denned, supramedian a little longer 

 than broad, the sides nearly straight. Petiole broad at apex, its sides depressed, above 

 longitudinally striated, the raised central part bordered, finely longitudinally striated. 

 Apex of abdomen acute. Legs stout ; the anterior tibiae and tarsi obscure ferruginous 

 in front. Areolet 5-angled, the sides a little converging above. 



In some specimens the apex of the petiole is rufous. The coloration of the body is 

 the same as in I. meridionalis ; but it is easily distinguished from that species by the 

 yellowish wings, with the areolet converging above ; and it is also a stouter insect.

Smooth, shining, punctured, the punctures on the head and mesonotum distinctly 

 separated ; base of metanotum opaque, finely rugose, the apex more shining and more 

 strongly punctured. The upper metathoracic areas obsolete, the lateral not very 

 clearly defined. Postpetiole strongly rugose, the rest of abdomen finely punctured, 

 semirugose. Gastrocceli large, deep, aciculate. On the head, the part above and 

 behind the antennae is black ; the rest, including the mandibles (except their apices, 

 which are black), being white. Clypeal foveae large, front broadly but not acutely 

 projecting, a furrow on either side of the projection. On the thorax, the sternum, the 

 lower part of the mesopleura, a line on the pronotum, the tubercles beneath the tegulae, 

 two small marks in centre of mesonotum, the apical three fourths of the scutellum, 

 the postscutellum, two small marks at base of metanotum, one beneath the hind wings, 

 a larger one on the metapleurae over the coxae, and two roundish ones at apex of meta- 

 notum, close to the sides, white. The four anterior legs are yellowish white beneath ; 

 above they are broadly lined with black ; the apical joints of the tarsi are entirely 

 black ; the anterior legs are entirely black, except a large mark on the underside of 

 the coxae and a mark on their base behind, which are yellow ; the greater part of the 

 femora beneath and the tibiae beneath in the middle are reddish. The apex of the 

 petiole and of the postpetiole is black. Areolet 4-angled, the top triangular. Antennae 

 longish, the scape yellow beneath.
