fitting mandibles, very large and not apically impressed clypeus, 

 normally broad wings, and shorter terebra. I have fouad it 

 necessary to modify but very slightly the generic diagnosis, in 

 order to include the following Oriental form, which difiers in 

 having the metatliorax not longer than high, in its less clearly 

 defined area;, smoother abdomen and the relative lengths of its 

 segments. The alar nervures are also peculiarly disposed, the 

 internal cubital coalescing Avith the first recurrent at its junction 

 M'ith the anal in such a manner that the anal is continuous with 

 he median ; in the hind v\ing the nervellus antl all the apical 

 nervures are wanting. 



Its position is still a moot point ; though strictly speaking the 

 subsessile, and often rugose, abdomen, lack of all trace of areolet 

 and distinctly exserted terebra, place it incontrovertibly in the 

 PiMPLiNiE, among which its cubical head and elongate legs ally it 

 most closely with the Xoridini. Tschek says {loc. cit.) his genus 

 is " a further contribution to the Austrian Pimplid.t; " ; and 

 Bridgman (Entom. 1879, p. ll?9) " that it ought to remain among 

 the PimplibtE, and in Holmgren's section ii.A.a." ( = XoEiniNi). 

 Thomson, however, places it in his subtribe Thtmarides of tlie 

 Tryphoninje, and no doubt can remain that, wherever placed, it 

 cannot be separated from Thymaris, a genus of far less Piinplid 

 facies. On the whole, I am inclined to think with the last author 

 and Gravenhorst, that, in spite of its cubical head and exserted 

 ovipositor, it is a true Tryphonid and certainly not one of the 

 LissoNOTiNi, among which it is placed as synonymous with Hyho- 

 phanes by Ashmead, who probably followed up Marshall's position 

 for it at the end of Phi/todietus. I still prefer to treat it here in 

 its strict and perhaps more unnatural position in the Pimplik^e, 

 which is further favoured by its now well authenticated ecto- 

 parasitic habits.
