ICHNEUMON. 149 



29. Ichneumon subpinguis. 



Niger ; flagello antennaram nigro, medio albo, apicibus tibiarum et tarsorum nigris ; alis hyalinis, nervis et 



stigmate nigris. $> . • 



Long. 9 millim. 



Hab. Guatemala, Cerro Zunil 4000 feet (Champion). 



Antennae longish, as long, if not longer, than the body, scarcely tapering towards the 

 apex. Head closely punctured, the face with a broad, flattish carina (broadest at the 

 apex) in the middle. Eyes margined, bordered with yellow in the middle in front and 

 behind. Thorax punctured all over, covered with a white silvery pubescence ; the edge 

 of the pronotum, and the tubercle below the tegulae clear yellow ; postscutellum large, 

 smooth, shining, with scarcely any punctures, its sides (as are also the sides of scutellum) 

 carinate. Mesopleurae hollowed posteriorly. Postpetiole broad, finely aciculate. 

 Gastrocceli large, striated. Abdomen broad, its apex somewhat acute ; punctured, 

 except at the apex, which is rather aciculate ; the punctures distinctly separated. 

 Metathoracic areas all defined ; lateral tubercle obtuse. Legs stout, longish ; coxae 

 punctured. Areolet converging somewhat above, but the nervures do not touch ; the 

 recurrent nervure is received nearer the base than apex. 



I. frivolus is perhaps the male of the present species ; but it is stated to have the tarsi 

 pale ferruginous, the cheeks prominent, and the sutures of the pleurae and the base of 

 the metathorax black. 



30. Ichneumon eros. (Tab. VII. fig. 14.) 



Hab. Guatemala, Volcan de Agua 8500 to 10,500 feet (Champion). 



In coloration this species is identical with /. subpinguis, except that the apices 

 of the hind tibiae and of the tarsi are not black, and that there is no trace of yellow 

 on the pronotum. The antennae are similar in form, but, if anything, thicker at the 

 apex ; they are also ferruginous, except at the apex, which is broadly black, and the 

 four joints in front of the black apical joints, which are yellowish white ; they are nearly 

 as long as the body. The eyes are bordered with yellow. The face projects in the 

 middle, and the clypeus projects still more, being separated from the part above it 

 by a transverse depression. Head and thorax finely punctured; the pleurae at the 

 posterior end obscurely and longitudinally striated. Scutellum aciculated, convex, broad 

 on the disc, the sides carinate, the keels meeting on the upper part behind, but they 

 are not very distinct at the place of union. Metanotum obscurely rugose at the base, 

 aciculate at the apex; all the areae clearly defined; the upper median area a little 

 broader than long, the anterior part rounded; lateral tubercles conspicuous. Post- 

 petiole broad, finely punctured, the centre not raised. Gastrocceli transverse, broader 

 than long, smooth, shining ; the extreme base of the second segment forms a ridge, 

 with a transverse furrow at its apex, uniting the gastrocceli. Abdomen opaque, 

 finely punctured. Areolet nearly converging above; stigma black.
