 longer than broad, sliglitiy convergent above and angled at the 

 reception of the second recurrent nervure ; nervelet wanting ; 

 nervellus centi'aliy intercepted.

Tbe position of this geiuis rests entirely upon the situation of 

 tlie petiolar spiracles, which was not very clearly described by its 

 author; if they be central it is a Pimplid, if beyond the centre it 

 is a Cryptid. In its cubical head, indistinctly sulcate inesosternum. 

 elongate legs, constricted front tibia; and simple claws it agrees 

 with Echth)-iis, which is the only other genus in the Pi.mpun.i; 

 possessing a pentagonal areolet, but it is easily differentiated from 

 that genus by the indistinctly discrete clypeus, which is not 

 centrally produced, the tuberculate pronotum, linear metathoracic 

 spiracles, stout antenufe, and especially by the abnormally de- 

 velo])ed penultimate abdominal segment. Its auth.or remarks (?06\ 

 cit.): — "I am not quite certain as to the exact location of this 

 genus. It has some affinity Avith the Cuvptixa. The position of 

 the spiracles on the petiole sepai'ates it from the Cryptina. The 

 very large hypopj'gium is somewhat as in Ac.tmttxi, but it cannot 

 be referred to any of the described genera in that grouj). The 

 depressed clypeus in some of tlie species is similar to what it is 

 in the Xoeiuini, and tliey have some relatiouship to Echthrus. 

 Probably the natural position of Torhda is with the Xoridcs. The 

 ■species are very large and handsome — among the largest of the 

 IcHNEUMONiDiE.*' An examination of .the types of all the known 

 species enables me to place it close to Nyxcoj^hilus, Forst. (nee 

 Thorns.), though it is not synonymous therewith.
