232 P. CAMERON. HYMENOPTERA. 



the apex, in front occupying the anterior part and the apical half, in the middle extending backwards 

 to near the 2 nd transverse cubital and the récurrent nervure, at the apex to near the anal nervure; 

 body and legs covered densely with longish fulvous hair, the hair on the tibiae denser and 

 shorter than on the femora, that on the tarsi stiffer than on the tibiae. Smooth and shining. cf. 



Length S mm. 



Antennae densely covered with a short stiff pile; the scape and following joints luteous ; 

 the basai 7 or 8 joints of the flagellum reddish brown. 



ICHNEUMONIDAE. 



Amblyteles? 



1. Amblyteles} triangulifer sp. n. 

 Bivak Island, January. 



Black, the palpi, tegulae, scutellum, metanotal spines. a longish triangular mark under 

 the hind wings, the apical third of the post-petiole, a transverse mark on the sides of the 

 2 n <l at the apex, roundly narrowed from the outer to the inner side at the base, a line on 

 the apex of the 3 ld , the base roundly narrowed, the middle hardly half the width of the 

 outerside, a semicircular mark on the penultimate and the whole of the last, whitish yellow; 

 legs black, the anterior femora and tibiae in front testaceous, the base of the middle coxae 

 broadly below in front, the posterior on the basai half above, the apex of the spot irregularly 

 incised, the anterior trochanters, the apical joint of the 4 posterior, the apical half of the 

 ist tarsal joint and the whole of the 2"d to 4*, whitish yellow; the calcaria black. Wings 

 hyaline, iridescent, the nervures and stigma black; the transverse médian nervure received 

 very shortly beyond the transverse basai; the areolet almost 4-angled, the nervures nearly 

 touching in front; the disco-cubital nervure broken by a stump. The 6th to the iithantennal 

 joints white, black above. Ç. 



Length 10 mm. 



The face below the antennae is raised into a triangle and is sparsely weakly punctured; 

 the clypeal foveae are large, deep. Labrum piceous. Front and vertex smooth. Temples very 

 short, sharply oblique, the occiput deeply roundly incised. Pro- and mesothorax smooth, 

 with a plumbeous hue ; the metathorax closely, distinctly punctured, the metanotum more 

 strongly than the metapleurae; the areola open in the middle behind, the 3 basai areae being 

 thus continuous; it is large, a little longer than wide, its apex rounded inwardly; the spines 

 are large, rounded at the apex, longer than they are wide at the base. Post-petiole weakly, 

 sparsely punctured; the middle raised, clearly separated from the narrower sides. The scutellum 

 is roundly raised, wider a little than long, narrower at the apex, the sides at the base keeled. 



This species is not typical Amblyteles; it probably forms the type of a new genus. 

 Characteristic is the raised triangular space on the top of the face; the greatly reduced temples 

 are différent from what they are in the genus just mentioned ; the scutellum is more convex 

 and the antennae are more slender, with the joints more elongated ; the gastracoeli are only 

 indicated by 3 or 4 longitudinal striae; the sheaths of the ovipositor are broad and distinctly project.
