ICHNEUMON. 175 



Hab. Mexico (SalU). 



Head and mesonotum punctured, but not strongly, scarcely dilated behind ; the 

 centre of the vertex is black to near the antennae, and behind the black is prolonged, on 

 either side, to the eyes. The outer black lines on the mesonotum are united behind, and 

 in front they are united to a narrow line which extends backwards to the tegulae and 

 beneath the latter there are two small black lines. The suture between the meso- and 

 metanotum is black nearly all round, and there is a transverse line behind the post- 

 scutellum ; the central line on the metanotum is narrow. Scutellum raised, the sides 

 carinate. Metathoracic arese clearly denned ; without lateral tubercles. Petiole smooth, 

 shining, impunctate, the sides carinate, a longish fovea at the apex ; postpetiole punc- 

 tured, the sides depressed above. Gastrocceli indistinct. Abdominal segments strongly 

 punctured ; the second and third segments have the basal half black, and the black 

 bands are of nearly equal width throughout ; the black on the other segments extends 

 beyond the middle at the centre, but is contracted at the sides. There is a small black 

 mark on the inner side of the posterior coxae at the base, and another at the apex on the 

 outer side ; the line over the posterior femora is fuscous rather than black. Areolet 

 5-angled, square above.
