OMOTOXUS. 215 



spots of pale cinereous. Antenna: robust, finely dilated towards the 

 apex ; the first to fourth joints flavous, fifth and sixth rufo-flavous, 

 sixth and seventh testaceous, eighth to eleventh flavo-fuscous. Leys 

 flavous, suffused with rufous ; the posterior femora on their under 

 surface being darkly fuscous. 



This species differs from 0. nodosus in its less transverse and 

 narrower thorax; from 0. Cayensis by its larger and more robust 

 form, and by the more depressed basal angles of the thorax. 



From Surinam (Paramaribo). In the collections of Herr Dohrn 

 and the Rev. H. Clark.

Oblong-ovate, robust, broad, punctate-striate, clothed throughout 

 with a fusco-flavous pubescence. Head short, transverse, slightly 

 produced in front : between the labrum and the base of the antenna) 

 is a transverse plane and glabrous depression ; at the insertion of the 

 antennae is a medial longitudinal fovea, sharply denned and narrow, 

 extending upwards and meeting a broad transverse depression which 

 connects the inner margins of the eyes ; the eyes are large and tole- 

 rably globose, situated at the base of the head ; the surface is very 

 finely clothed throughout with fiavo-testaceous pubescence ; in colour 

 flavous, the base being margined with fuscous. Thorax transverse, 

 rectangular ; the anterior margin subemarginate ; the sides distinctly 

 marginate : at the antemedial centre of the disk are two oblong and 

 distinctly prominent tubercles ; behind these, a transverse depression 

 at the base extends not quite so far as the basal angles, but subcir- 

 cularly upwards; at the lateral margins (immediately above the 

 margination) on either side are two smaller tubercles : the surface is 

 clothed throughout with fine flavo-fulvous pubescence ; the colour 

 being ferrugincous, suffused at the sides with fuscous. Seidell inn
