and slightly discoloured at the apex, clothed sparingly with rather 

 long greyish hairs, the 3rd, 4th and 5th also with a slight lateral 

 fringe, segments beneath finely aciculate their margins with fringes 

 of rather long white hairs. 8th ventral segment subtriangular at 

 the base, produced into a somewhat short, parallel-sided, apical 

 process, hardly widened at the extreme apex which is truncato- 

 emarginate, sides fringed with golden hairs. Armature of very 

 unusual form, the lobes of the stipites being very large and their 

 anterior margins strongly reflexed laterally, the blades are scarcelj'- 

 longer than the lobes, narrow and deeply channelled along the sides, 

 sagittse narrow and pointed. 

 Long. 13 mm.

This species is most like nobilis, Mor., but the shorter 

 antennae and the proportionately longer 2nd joint of the 

 flagellum as well as the form of the armature will dis- 

 tinguish it easily.

A rather obscure-looking species but one which I fail to find 

 described, it somewhat resembles a very large member of the 

 minutula group with entire abdominal bands. 



jj. Black, head and thorax clothed with greyish- white hairs, 

 clypeus shining strongly and remotely j^unctured the surface 

 between the punctures finely rtigulose with traces of longitudinal 

 striae, face above the antennae striate, 2nd joint of the flagellum as 

 long as the next 3 together, 3rd and 4th slightly wider than 

 long, rest of the joints subquadrate ; mesonotum finely rugulose 

 with a superficial remote puncturation, its hairs inclining to 

 ochraceous in colour, propodeal area rugulose : abdomen finely 

 rugulose, somewhat shining, sparingly clothed with semierect white 

 hairs those towards the sides and on the first two segments longest, 

 apices of the segments discoloured, 2nd and following with a rather 

 thin fringe-like band of white hairs, these bands more developed at 

 the sides and on the apical segments, beneath with the apices fringed 

 with very long hairs, apical ventral valve narrow, slightly dilated 

 and entire at the apex fringed with long golden hairs in a fan-like
