Ichneumon discoensis n. sji. 



A specimen from Disco Island, August lOtli, does not agree with 

 any of the species heretofore recorded from Greenland or Arctic 

 America. 



The following description will aid in distinguishing it : Black ; the 

 apical half of the femora, the tibise, tarsi, the apex of the first, the 

 second and third entirely and the base of the fourth abdominal 

 segments, above and beneath, and a spot on the scutelkim, reddish 

 brown ; the tips of fore tibipe and the apical tarsal joints dark ; head 

 and thorax clothed with short, black pubescence, finely and evenly 

 punctured ; clypeus truncate ; antennae situated at a point opposite 

 the middle of the eyes, much shorter than the body, entirely black, 

 38-jointed, the scape short and stout, hirsute beneath ; wings sub- 

 hyaline, with a violaceous reflection, the nervures and stigma black ; 

 metathorax strongly punctured, rugose on the sides, the posterior 

 face enclosed by a very strong ridge, bicarinated ; the upper surface 

 bears four ridges, the two inner ones by far the shortest, all four 

 being connected with the ridge enclosing the posterior face ; at 

 the top of the metapleurse there is another strong, curved ridge, 

 which extends nearly to the posterior coxse ; femora finely punct- 

 ured ; abdomen with fine close punctures, the third segment de- 

 pressed at base. Length about ll*5mm. 



Exolytus ?p. ? 



A small species with the head and thorax black, the four anterior 

 legs except the coxse and trochanters, the hind legs from the apex 

 of the femora, all brownish.
