Ti'iepeolus Norce, sp. n. 



$ . — Length about 8| mm. 



Black, with the usual markings only slightly yellowish ; 

 hair on middle of face pure white ; legs clear red, spurs of 

 middle and hind legs black ; no red colour on thorax ; tegulae 

 apricot-colour; scutellum low, obscurely bilobed, the lateral 

 teeth black and short. Clypeus shining, with many very 

 minute punctures and a few large ones; mandibles red except 

 at base and apex ; labrura black, a little reddish at sides ; 

 first three antennal joints and base of fourth ferruginous ; 

 sides of vertex with large well-separated punctures on a 

 shining ground ; mesothorax exceedingly densely punctured, 

 the two median stripes of hair short, not attaining the ante- 

 rior margin ; pleura hairy in fiont and with a large transverse 

 patch of hair ; lower part of pleura densely punctured, but 

 at one place a little of the shining surface shows ; dark trans- 

 verse mark on first abdominal segment essentially as in 

 T. occidentalis, but the posterior band interrupted; segments 

 2 to 4 with even entire bands, that on 2 with lateral processes 

 directed forwards so as to make with the band an angle of 

 about 45° ; sides of fifth segment with white tomentuai ; last 

 ventral segment normal. 



In nearly all respects exactly like a small edition of 

 T. occidentalism but the hair of the abdomen is less yellow, 

 the pygidial patch is narrower, and the scutellar teeth are 

 less developed. In size and general appearance it closely 

 resembles T. callopusj Ckll. Tlie colour of the spurs will 

 readily separate it from 2\ Hopkinsi.
