T. atripennis Kuhnt, which, so far as the fragmentary 
descriptions indicate, appears not to differ from 7’. nagripen- 
nis Mots., has only the elytra and scutellum black, whereas 
in this species the head, scutellum, elytra, mesosternum 
and metasternum and the two penultimate joints of the 
antenna are black and the rest of the body pale yellow 
(not orange). There is also generally a very narrow and 
inconspicuous dark marginal line at the middle of the 
front and hind edges of the pronotum. 
The first elytral stria is distinct, strongly oblique 
anteriorly and running close to the suture behind. The 
metasternum is very feebly punctured in the middle, 
more strongly at the sides. The club of the antenna is 
moderately broad but not closely-jointed.

It is possible that 7’. atripennis Kuhnt is a phase of 
this species without the two marginal black spots upon 
the pronotum. This is happily immaterial, since the 
name atripennis falls, having been previously used for a 
closely-related species by Gorham, but entirely misplaced 
by him, Tritomidea, as I pointed out in 1917, being 
synonymous with Euxestus. T'. repetita is entirely orange- 
red in colour, with the exception of the eyes, a spot in the 
middle of the front margin of the pronotum, a correspond- 
ing spot at the hind margin and the elytra. This pattern 
like others is recurrent in this genus, most of the species 
of which seem to be rather localised, but the very similar 
T. motschulskyi Bedel and T'. oppositipunctata Gorh. have
