158 HYMENOPTEBA. 



in the centre, smooth, shining, the sides keeled ; postpetiole closely covered with large 

 punctures. The rest of the abdomen is more strongly scabrous than the thorax ; the 

 segments are contracted at the base ; towards the apex the black at the base of the 

 segments becomes less and narrower in the middle. The anterior femora are more or 

 less ferruginous ; the black on the underside of the middle pair inclines to piceous. 

 The knees are all ferruginous. The tibiae (except the hind pair) are of a lighter 

 ferruginous colour than the rest of the body ; the spurs are also of this colour. Areolet 

 5-angled, a little narrower on the upperside ; the recurrent nervure is received beyond 

 the middle ; the yellow band extends from the base to a little beyond the apex of 

 the stigma. 



Closely related to I. godmani, which may be easily known from the present species 

 by being longer and stouter, by the metathorax being black, and by the metathoracic 

 areae being all clearly traced. The abdomen is not so strongly scabrous, and the 

 antennae are yellowish in the middle.

Ferruginous ; antennis, abdominis basi, pedibusque posterioribus nigris ; antennarum medio apiceque tarsorum 

 flavis ; alis nigris, medio stigmateque flavis. 3 .

Hab. Panama, Volcan de Chiriqui 4000 to 5000 feet {Champion). 



y Very near to /. melanopoda, and not differing from it in sculpture and clothing ; but 



(f it is broader both in the thorax and abdomen ; and the latter has only the base of the 



fP petiole black. The antennae are longer and yellow in the centre ; the tips of the tarsi 



are yellow ; the four anterior tibiae are yellow in front ; the suture separating the meso- 



and metathorax is black ; and the wings are much blacker in tint. 



It is too large to be the male of /. lymphatus, which has, besides, the four anterior 

 legs entirely ferruginous, and the hind tarsi almost entirely black ; the petiole, too, 

 bears no black, nor does the suture of the metanotum, while the gastrocoeli are more 

 distinct, these in /. panamensis and /. melanopoda being obsolete. 



50. Ichneumon lymphatus. (Tab. VII. fig. 19.) 



Ferrugineus ; apice antennarum pedibusque postieis nigris ; alis fumatis, medio fl avo-byalinis, stigmate flavo. 5 . 

 Long. 9 millim. 



Hab. Guatemala, San Geronimo {Champion). 



Strongly punctured, covered with a fuscous pubescence. Head buccate ; face with a 

 pale longish pubescence ; eyes with a distinct narrow border all round. Scutellum 

 moderately elevated ; sides keeled in front, indistinctly keeled behind. Postscutellum 

 n broad, finely and longitudinally striated. Metathoracic areae clearly defined behind, 



hollow in the middle. Petiole bicarinate on either side, the keels extending to the 

 base of the postpetiole, which is strongly punctured ; sides of the petiole with a row of
