ICHNEUMON. 177 



areae and tubercles obsolete ; the extreme base is smooth and impunctate, beyond this 

 smooth space it is for a short distance striated (the middle transversely, the sides longitu- 

 dinally), the rest is punctured. The pleurae are yellow, bordered all round with black ; 

 the spiracular area is yellow, black in the middle. The centre of the metanotum is black, 

 broadly bordered with yellow, the yellow being continued up on either side of the apex 

 of the supramedian area ; the base is black. Petiole longitudinally striated, the striae 

 continued into the middle of the postpetiole, which is raised on either side and laterally 

 depressed at the base; the sides and apex of the postpetiole punctured. Abdomen 

 longish, becoming dilated to the fifth segment ; the apex acute ; the segments contracted 

 at the base ; strongly punctured ; gastrocceli large, deep, transverse, broader than long,, 

 aciculate; the ventral surface is yellow to the base of the ovipositor, and with three 

 broad black marks on either side. Legs stout. Coxae large, especially the posterior 

 pair; the two anterior pairs are entirely yellow; there is a large black mark on the- 

 posterior pair beneath at the base, and a narrower mark above, the extreme apex being 

 also bordered with black. The four anterior legs are entirely yellow beneath, except a 

 black mark at the base of the middle tibiae ; above they are lined with black, except 

 a long yellow mark in the centre of the yellow on the femora and a small yellow line 

 at the base of the middle tibiae. The hind femora are yellow, black at the extreme 

 base, and broadly black at the apex ; hind tarsi and spurs entirely black. The 

 anterior metatarsi are sharply curved at the base, the spurs being also curved. The 

 middle femora are short and thick, and have a blunt keel on the underside; this- 

 keel projects at the apex and forms a leaf-like tooth. The middle tibiae are narrow 

 at the base, and have also a blunt tooth, beyond which the tibia thickens. Areolet 

 5-angled, converging above.

Hab. Mexico, Takubaya (BilimeJc). 



Antennae stout, involute, the third joint longer than the fourth. Head and thorax 

 closely punctured. Scutellum apparently flat*; the tubercles in front of it white. 

 Metathorax broadly rounded, but slightly hollowed in the centre at the apex - y 

 without tubercles ; all the areae distinct ; upper median area harp-shaped, broader than 

 long ; the base striated, the apex and sides rugosely punctured. Petiole keeled, finely 

 punctured ; postpetiole reticulate-punctate in the middle, the sides finely punctured. 

 Gastrocceli very broad and deep, finely aciculate. Abdomen with the second segment 

 reticulate-striate in the middle, the sides coarsely punctured ; the third segment coarsely 

 and longitudinally striated in the middle, the sides coarsely punctured; the fourth 

 * The pin goes through, it, so I am unable to describe it fully.
