The taAvny-yellow spots of the elytra are very indis- 
tinctly limited, though in the same position as in T. lati- 
Jicus, etc. The three sharply impressed, simple, elytral 
strijB are successively shorter from the sutural one, being 
abbreviated both towards base and apex ; the first puncture 
is exactly at the commencement of the third stria, the 
second lies a little beyond its termination. 
T. pozcilopterus, n. sp. 
T. scydmceno'idi (Neitn.) proxime affinis, at paulo major, 
thorace postice magis angustato, elytris fusco-nigro macu- 
latis; rufo-testaceus, convexus, politus; antennis pal^nsquc 
fuscis, basi et pedibus pallido-testaceis, elytris utrinque 
maculis duabus transversis fulvo-testaceis, apice et medio 
nigro-plagiatis; striis tantum duabus, exteriori abbreviata.

The elytra have only two strife, as in T. scydmcenoides; 
the eighth is very strongly impressed and entire. The 
colour of the elytra is glossy chestnut-red, but becoming- 
black in the middle of the spaces between the pale spots ; 
these spots are more transverse than in the numerous allied 
species, the posterior one being almost a fascia interrupted 
at the suture. The thorax is rather longer than in T. 
scydmceno'ides ; although transverse, and broadly rounded 
anteriorly, it is rather strongly narrowed towards the base. 
The frontal grooves are very wide apart, forming very 
short strias.
