PHAENOLABRORYCHUS, new genus. 



Type. — Fhaenolabrorychus anisitsi, new species. 



Related to Lahrorychus Foerster, but differs greatly in the remarka- 

 bly produced propodeum which has a smooth cylindrical process extend- 

 ing from the base of the hind coxae ahnost to the apex of the proximal 

 joint of the hind trochanters, by the propodeal spiracles being apparently 

 concealed in a pit, by the furrowed scutel, by the hind ocelli almost 

 adjoining the occipital carina, by the anterior edge of the clypeus 

 which is rounded and provided with two nipple-like processes, by the 

 presence of notauli, by the decidedly antifurcal nervulus, by the 

 nervulus not being broken, by the hind metatarsi being nearly four 

 times as long as the succeeding joint and by the second abdominal 

 segment being approximately as long as the first. The above descrip- 

 tion is based upon a comparison with a male of Lahrorychus tenui- 

 comis Gravenhorst.

 other than to the apex, but nearer to the apex than to the base and its 

 petiole nearly cylindrical and not at all carinate, in the mesonoto- 

 scutellar carinae not reaching to the middle of the scutel, in the distance 

 between the lateral oceUi being apparently a httle less in the female
