224 OMOTOTUS. 



the anterior angles depressed; the sides submarginate and recti- 

 linear ; at the base is a broad transverse depression. Scutellum 

 almost obsolete. Elytra broad, robust, punctate-striate, the punc- 

 tures being broad and shallow, but for the most part concealed by a 

 fine and thick testaceous pubescence, which is especially apparent 

 along the line of the suture : two circular suffused fuscous -spots 

 occupy the space close to the scutellum, between the second and 

 fifth stria3. Antennae, tolerably long and robust ; the first and second 

 joints dilated (the first being, as in the other neighbouring species, 

 slightly reflected outwards, and the second short, ovate) ; the third 

 to fifth joints attenuated and elongated ; the sixth to eleventh joints 

 shorter and slightly broader; the colour of the first to fifth being 

 flavous, sixth to eleventh fuscous. Legs: the posterior pair sub- 

 elongated; flavous throughout.

17. Omototus sexnotatus. (TAB. IX. fig. 2.) 



0. oblongo-ovatus, parallelus, ferrugineus, flavo-pubescens ; capite 

 leviter producto, inter oculos in forma litterce T foveolato ; thorace 

 transverso ; elytris punctato-striatis, nigro-maculatis (maculae 

 duce apud Jiumeros, alterce mediae, alter ceque ad basin disponun- 

 tur) ; antennis filiformibus, subincrassatis, ferrugineis, articulis 

 7w_ll> nigris ; pedibus flavis. 



Long. corp. 1| lin., lat. | lin. 



Oblong-ovate, parallel, ferrugineous, clothed throughout with a 

 fine yellow pile. Head short, hardly produced, with an obscure 

 transverse carination between the eyes, which joins at its centre a 

 longitudinal ridge extending to th^ base of the antennae (forming 

 together the character of the letter T) ; the surface at the base of the 

 head is levigate and finely punctate. Thorax transverse, marginate, 

 at its anterior angles depressed ; the antemedial surface is rounded ; 

 the base is transversely depressed. Elytra broad, robust, cylindrical, 

 short, punctate-striate, very finely pubescent, with six irregular black 

 spots, two at the scutellary angle (approaching, but not touching, the 

 suture), two (which are oblong in form and obscure) postmedial, and 

 two subapical and sutural. Antennae, somewhat robust, with a ten- 

 dency to dilatation towards the apex ; the five apical joints black, 

 the rest ferrugineous. Legs flavous. 



The size and arrangement of the six spots on the elytra (besides 

 its parallel subcylindrical and short form) are quite sufficient to sepa- 

 rate this species.
