from Engano (an island near Sumatra) and from the Abor country (see p. 195). The 
three Seychelles species may be distinguished as follows :—

Form oblong-oval, sometimes very slightly narrowed behind, with the sides of the 
thorax and elytra explanate. Colour more or less dark brownish ferruginous with margins 
and legs lighter, antennze and palpi testaceous. Subopaque, this being due to extremely 
fine reticulation or rugulosity of the surface; with a compound microscope the head is 
seen to be closely covered with a sculpture of extremely fine transverse lines, and the 
prothorax with a reticulation consisting of excessively fine punctures and scratches, while 
the surface of the elytra is very minutely rugulose-reticulate : a few fine hairs can also be 
seen on the thorax and elytra. The disc of the thoraw is slightly elevated or tumid on 
either side behind, which causes the sloping sides of the disc to appear vaguely impressed 
on either side in front of this elevated portion. The elytra are without any sutural stria ; 
they have regular series of rather large but very shallow punctures; the space between 
the first series and the suture is strongly elevated, and the 3rd, 5th, and 7th interstices 
are also elevated into blunt but perfectly well-marked carinze running the length of the 
elytron nearly to its posterior extremity : thus the dorsal part of the elytron has blunt 
longitudinal carime, and two series of punctures in each interval between them; the 
intermediate interstices are only very slightly convex; in the sloping lateral part, the 
alternate interstices are not elevated into carinze; both the carinze and the other 
interstices bear lines of very minute punctures; at the base of each elytron, a little 
outside the middle and in the region of the outermost carina, is an obtuse but quite 
distinct boss, or elevation. The elevated part of the mesosternum (Pl. 14, fig. 9) forms 
an area longer than broad, with sides nearly parallel and strongly margined, its surface 
slightly concave and with only a minute trace of a median elevation behind. The under- 
surface of the body is beautifully reticulated, and the femora, the elevated central part of 
the metasternum, and the abdominal segments, bear very sparse short hairs.
