Antennse brown, the basal part of many of the middle joints 
pale testaceous. Thorax with the disk smooth, even; lateral 
tubercles very obtuse. Elytra punctured throughout, towards 
the base densely, towards the apex sparingly ; they are sooty- 
brown varied with obscure rusty-yellow patches ; each has on the 
side, about the middle, a large greyish-white triangular spot, not 
generally touching the suture. Under-surface of the body 
brown ; legs pitchy-black, clothed with ashy pile. Tarsi mode- 
rately slender.

Genus ^gomorphus. 
Thomson, Class, des Ceramb. p. 336. 
Char, emend. Body narrow, thick, and somewhat convex. 
Head as in Oreodera, the muzzle being very slightly prolonged 
beyond the lower margin of the eyes, its anterior angles obtuse : 
the eyes distant on the vertex. Antennae rather shorter ; the 
proportions of the joints the same ; but they are not fringed 
beneath, as in Oreodera. Sides of thorax furnished with a large 
conical tubercle. Prosternum behind and mesosternum in front 
steeply inclined ; clothed with long hairs in the S (at least in jE. 
moniliferus) . Anterior acetabula angulated. Second and third 
ventral segments contracted in the middle in the $ ; the fifth 
very large, its apex truncate-emarginate and densely hairy. Tarsi 
broad, claw -joint long ; fore tarsi neither dilated nor fringed in 
the 6 . 
The name of this genus first appears in Dejean^s Catalogue, 
but it was first characterized by M. Thomson in the present 
year; the characters given, however, although numerous, omit 
the chief peculiarities of the group. The thickness and con- 
vexity of the body, nakedness of fore tarsi in the male, and shape 
of the sterna are the chief points of distinction. M. Thomson 
places it in the group Trypanidiitse, — an arrangement quite 
unintelligible on his system,, as it does not agree at all with the 
characters of the section to which the Trypanidiitse belong.

Head clothed with a fine grey pile, leaving three narrow longi- 
tudinal lines on the vertex brownish black. Antennse shorter than 
the body, grey ; tips of the joints (from the third) dusky. Thorax
