ICHNEUMON. 161 



posterior pair are yellow (except at the extreme base), and have a broader ferruginous 

 space at the apex. On all parts of the body the black runs into ferruginous ; on either 

 side, at the apex, the postpetiole is yellowish, as is also the apex of the second segment 

 at the side. Legs robust. Anterior tibiae curved at the base. Areolet broad above, but 

 the lateral nervures still converging ; the recurrent nervure is received a little beyond 

 the middle. 



55. Ichneumon opiparus. 



Brunneo-rufus ; anteimarum scapo medio, abdominis segmentis l°-3 m apice tibiarumque dimidio basali, flavis ; 



alis flavo-hyalinis, stigmate testaceo. $ .

Hob. Mexico {Bilimek). 



Head and thorax opaque, coarsely granulated, closely covered with a pale pubescence ;, 

 clypeus strongly punctured, foveate at the base on either side, the part above it broadly 

 projecting in the middle. Scutellum slightly elevated above the mesonotum, clearly 

 raised from the sides, carinate at the base, longer than broad, narrowed towards the apex,, 

 which has a gentle slope. Metathorax rugose ; supramedian area distinct, longer than 

 broad, narrowest at the apex ; the other arese not defined, except indistinctly at the base ; 

 the apex has an almost perpendicular slope, and is hollowed in the centre ; the lateral 

 tubercles blunt, but distinct. The centre of the posterior part of the metathorax is 

 brownish red like the rest of the body (the red forming a broad straight line) ; on either 

 side of this, and extending a little on to the pleurae, the colour is pale yellow. Petiole 

 black, smooth, and shining ; the carina? well defined at the apex ; postpetiole longitu- 

 dinally and strongly striated. The rest of the abdomen is finely and closely punctured ; 

 the base of the second segment longitudinally striated. Gastrocceli broader than long, 

 shining and aciculate in the middle. The apices of the first, second, and third segments 

 are yellow, the remaining part for the greater extent black ; the apical segments are 

 obscure dull red. The pronotum is narrowly edged with obscure yellow. The antennae 

 beyond the broad yellow portion are almost black. The yellow on the four anterior tibiae 

 is not so distinct behind as it is on the front ; the sutures of the pleurae are yellowish 

 for the most part. Areolet 5-angled, broad above, the lateral nervures but slightly con- 

 verging. The body is more densely pilose and more opaque than in the preceding species. 



56. Ichneumon tepidus. 



Sordide rufus ; sterno abdominisque segmentis basi late nigris ; alis flavo-fumatis, nervis testaceis. <$ .

Head (except the face) and thorax opaque, closely punctured and covered with a 

 dense pale pubescence. Pleurae longitudinally punctured, the punctures almost forming 

 striations. The basal half of the antennae, the four anterior legs, the basal half of the 

 hind tibiae, the hind tarsi, and the apices of the first to the fourth (the second very
