218 OMOTOTUS. 



vis, 9-11 rufo-ferrugineis ; pedibus ant ids flams, mediis et pos- 

 ticis rufo-ferrugineis. 

 Long. corp. 2 lin., lat. 2 lin. 



Oblong-ovate, broad, robust, subparallel, deeply punctate-striate, 

 clothed throughout with a fine fulvous (interspersed with fulvo -fus- 

 cous) pubescence. Head short, transverse, slightly produced in front ; 

 above the labrum is a transverse glabrous carination : eyes tolerably 

 large, extending laterally as far as the anterior angles of the thorax ; 

 between the eyes is a transverse and obsolete (almost imperceptible) 

 depression : the surface is flavous, clothed with a flavous pubescence ; 

 the colour near the labrum being rufous, and at the base fuscous. 

 Thorax transverse, almost quadrate, rectangular ; the anterior angles 

 subdepressed ; the sides obsoletely marginate and obscurely sinuate 

 (not, as in 0. Cayensis, rectilinear) ; the anterior medial disk is 

 elevated, and is divided into two parts by a broad and tolerably deep 

 longitudinal depression, thus forming two distinct antemedial tuber- 

 cles ; the base is transversely depressed, more deeply at the basal 

 angles ; there is also a slight depression close to the subsinuation of 

 the sides (which is not represented in 0. Cayensis) ; the surface is in 

 colour flavous, clothed throughout with flavous pubescence, medially 

 more darkly flavous. Scutellum triangular, clothed with fusco- 

 flavous pubescence. Elytra robust, considerably broader than the 

 thorax, subparallel, punctate-striate, neither the punctures nor the 

 striae being concealed by the pubescence ; near the scutellary angles 

 the surface is distinctly raised, and rendered more prominent by an 

 antemedial depression, which does not exist in 0. Cayensis ; the sur- 

 face is clothed throughout with a flavous pubescence, irregularly 

 mottled with flavo -fuscous and ashy-grey. Antennce incrassated 

 towards the apex; the joints first to eighth being flavous, and ninth 

 to eleventh rufo-ferrugineous. Legs : the anterior flavous ; the me- 

 dial and posterior rufo-ferrugineous.
