 mouth-parts have been removed.

<J. Clypeus bell-shaped, but somewhat rounded anteriorly and 

 strongly bent inwards at the apical angles. Hypopygium very 

 broadly truncate, not reaching beyond the epipygium, except a 

 short, narrow process to the base of the apical spine. 



£. The second abdominal segment has about thirteen trans- 

 verse carina?, those near apex most elevated, those near base 

 irregular. Fifth ventral segment longitudinally striated on 

 apical half. Pygidium truncate posteriorly, longitudinally 

 striated, with a spine on each side parallel to the lateral margin.

$. There is a specimen in the British Museum which I assign 

 to this species with some doubt. It is allied to T. annulatus 

 Kirby, from which it differs in the shape of the hypopygium 

 which is subtriangular, with an acute apical spine; and in the 

 epipygium which is less strongly striated and not deflexed. 

 There is a yellow spot on each side of all the abdominal segments, 

 not of the first five only as in Guerin's type. The clypeus is 

 shaped as in T. annulatus.
