Giraud (Ann. Soc. Ent. Fr. 4® s«5r. x. pp. 27-30) gives short characters

and its allies. He has bred that sp. from swellings in lower branches of 
young trees of Quercus pedmiculatus at Fontainebleau and Vincennes, and 
notes that its parasite is Ephialtcs innnis (Gr.). Ephippionotus hdeiventris^ 
Costa, S' = Cephus compressxts (F.), which is also a Janus, and attacks 
pear-trees; whereas the other two spp. of Cephus {pygmems, L., and arnn- 
dinis, Gir.) live in the stems of Graminaeem. The author considers tliis 
difi’orenco of habit to substantiate tlie generic differences.
