This species is about the size of Tr. prasinatus (Sell.), but it is 
proportionally more narrowed and elongated in all its parts, and has 
no ante-apical callosity on the elytra; moreover the greater elongation of 
the antennae in both sexes, and the narrowness of the rostrum and thorax 
approach nearer to Tribotropis pustulatus , F., Sch. It certainly exhibits a 
peculiar generic form, as genera are now understood by modern authors, 
very closely allied to the last-mentioned species. 
Head a little longer than broad, somewhat produced behind the eyes, 
slightly conically narrowed towards the rostrum by these organs, between 
which it has a raised ridge, being the continuation of that of the rostrum, 
where it is nearly obsolete at the base. Rostrum moderately dilated at the 
apex (especially in the females); its intra-lateral ridge on each side is also 
slightly indicated, obliquely approaching towards the base, finishing just 
at the transverse level of the tip of the frontal ridge and very near to it; it 
is, nevertheless, elevated and rugose near the apex above the antennal 
groove. Its indexed sides are punctate-rugose, slightly flattened. Its 
apex is triangularly emargiuate ; the upper side clothed (like the head) 
with a whitish or yellowish tomentosity ; sides and lower part denuded, 
black. 
Thorax subtruncate at the apex, where it is subtubular and bas two 
wrinkles on each side behind the eyes ; sides rather dilated to the middle, 
where the posterior carina ceases, nearly representing on the thorax a sub¬ 
semicircular line widely interrupted in its middle, not much in front of the 
base, thence slightly obliquely narrowed towards the base, which is trun¬ 
cate and thinly margined; disc shallowly depressed in front of the base 
and behind the apex; clothed like the head and rostrum, having two black 
tomentose apical lineolae and two basal maculae, more or less (although 
sometimes not) joined by an obsolete longitudinal blackish liue, subdenu-
