Symphiletes pubiventris, Pasc.) ; on the nndersurface a number of 

 spots (like those of the elytra) on the metasternum. some lines on 

 the mesosternnm, and the hind margin of each ventral segment. 

 The orange-red pubescence is also vaguely distributed over the 

 Qiiddle part of the pro- and meso-sterna and the legs. The pro- 

 thorax has no lateral tubercles, hut bears four or five transverse 

 impressions or folds, the presence of which causes the lateral 

 margins, viewed from above, to appear uneven. There is a fine 

 elevated transverse line across the middle of the prothorax, which 

 being unevenly elevated causes a slight appearance of a transverse 

 row of scarcely defined tubercles. The part of the prothorax in 

 front of the front fold is slightly narrower than the rest, but not 

 so markedly as in /. heros. The antennae are a little longer than 

 the body and of a pitchy colour, much clothed (probably entirely 

 in a perfectly fresh specimen) with slate-coloured pubescence, and 

 thickly ciliated beneath. In the typical specimen the 2nd ventral 

 segment bears a large patch of brown pilosity on either side and 

 there is a strong (but very short) spine on each front coxa.
