194 NEMATUS HJ1M0REH0IDALIS. 



20a. Nematus pallipes. 



Tenthredo pallipes, Fallen, Acta Holm., 1808, 110, 48. 

 Nematus pallipes, Thomson, Hym. Sc, i, 97, 20. 

 Nematus carinatus, Htg., Elattw., 199, 28. 



This species has been taken by Mr. C. Gr. Champion 

 at Aviemore in Inverness-shire. It comes nearest to N. 

 astutus and N. lativentris, but differs from both in the 

 legs and stigma being yellowish-testaceous ; the hind 

 femora are only slightly lined with black ; and in par- 

 ticular the apex of the middle lobe of the mesonotum 

 is U-shaped, not v-shaped as in the other species. 

 JSf. breadalbanensis is a narrower species than it ; has 

 the antennas longer and thinner; the abdomen is 

 longer ; the femora and coxa3 are broadly black ; the 

 rest of the legs whitish, not reddish-testaceous ; the 

 spurs are shorter, and the transverse basal nervure is 

 received nearer the middle of the cellule. The keel 

 on the mesonotum is indistinct, and there is also an 

 indistinct keel on the scutellum in my example of 

 pallipes. The third cubital cellule is longer and more 

 dilated at the apex than it is in astutus, and the wings 

 are of a much more decided fulvous tint. 



Nematus oeruleocarpus (Vol. II, p. 82). 

 Konow refers vicinus, Lep., to crassus. 



Nematus hemorrhoidals (Vol. II, p. 96). 



Konow gives pallicerus, Htg., as a synonym; while, 

 as will be seen (p. 99), I have treated it as identical 

 with capresd. 



Nematus circumscriptus, Foer., is no doubt distinct 

 from capreas.
