Closely allied to T. Jimicola (Wollast.) from the Cape 
Verde Islands. It is a little larger, less glossy, sides of 
thorax distinctly less rounded, and apex of the elytra less 
distinctly black. As in other species of Trechichus, and 
to a less degree Mizotrechus, the 8th stria is more sharjoly 
impressed than the rest, flexuous in the middle and led 
round the apex, at some distance from the margin, to the 
end of the suture, causing the discal surface of the elytra 
to form a slight fold over the impressed line. 
This species has a tooth in the emargination of the 
mentum, and therefore differs from the definition of Tre- 
cliichus given by Leconte after Zimmerman. I can confirm 
the statement of these authors that the mentum is tooth- 
less, in so far as I failed to distinguish a tooth in a specimen 
of T. umhripcnnis showed me by Dr. Leconte. It is so 
difficult, however, to be sure, without dissecting a specimen, 
that I think it unadvisable to form a new genus on this 
point of difference, until the North American species have 
been thoroughly re-examined* 
The present species, on dissection, proves to have a narrow 
horny ligula surmounted by two setai, with paraglossa3 
adherent to the upper angles, and there obliquely truncated 
upwards and outwards, Avithout being longer than the 
ligula; a very similar formation exists in the genus
