front, the clypeal carina is visible in the centre only, the piceous 

 antennal club is shorter than the whole pedicel, the marginal fringe 

 of hairs on the elytra is much shorter, and so is the pubescence on 

 the under side, nor are the hind legs bristling with so many erect 

 hairs. 



I have seen only one example of this species, and two, including 

 the type in the British Museum, of the other, yet owing to the shape 

 of the clypeal part of the head, coupled with the shorter antennal 

 club, I think T. titania is distinct from T. flavipennis.

Mentum very narrow, parallel, ligular part ogival, basal joints of 

 labial palpi massive, contiguous, set on the outer face of the ligular 

 part which they hide, apical joints cylindrical, truncate at the tip, a 

 little longer than the two preceding taken together ; maxillae slender 

 and having the maxillary palpi inserted at the apex and inwardly 

 a narrow, tooth-like process, obtuse and penicillate at the tip, 

 maxillary palpi long, the last one very elongated, cylindrical, slightly 

 inflexed towards the tip, mandibles triquetrous, sharp at tip, but 

 without molar tooth or fringe of short hairs ; antennae 9- jointed, 

 joints 3-5 of nearly equal length, 6 compressed, sharply acuminate 

 inwardly, 7-9 laminate, long and forming the club which is only a 

 little shorter than the whole pedicel ; clypeus more or less concave 

 with the anterior margin plainly raised, sloping in front, labrum 

 separated from the anterior part of the clypeus by a plain suture, 

 triangular, not notched at the tip, but occasionally with a slight 

 longitudinal impressed line in the centre, head as long as the clypeus 

 and separated from it by a transverse suture ; eyes large, bulging, 

 divided in the anterior part by a very short canthus ; prothorax 

 plainly narrowed in the anterior part, very little wider across the 

 median part than across the base which is bi-sinuate ; scutellum 

 broadly ogival ; elytra non-costulate and non-striate except for the 

 juxta-sutural stria which, however, is nearly obliterated, sub-parallel, 

 convex, covering half the broad propygidium, and having a row of 

 long setae along the outer margins ; pygidium sloping forwards almost 

 as much as in some South African Hoplince, on account of this great 

 development of the pygidium the abdominal segments are very 

 narrowed in the centre, and the penultimate segment has a distinct
