OMOTOTUS. 223 



art. 1-5 jlavo-testaceis, 6-9 dilatatis, nigris, 10 et 11 rufo- 

 testaceis. 



Long. corp. 2i lin., lat. 1 lin. 



Oblong-ovate, robust, flavo -pubescent, fusco-flavous. Head elon- 

 gate, somewhat produced in front ; above the base of the antenna) 

 (which are approximate), and between the eyes, is a transverse de- 

 pression, which is partially concealed by the flavous pubescence at 

 the inner margin of the eyes ; surface punctate and rufo-flavous. 

 Thorax quadrate (slightly elongated) ; the anterior angles slightly 

 prominent and subacute (extending laterally considerably beyond the 

 base of the head), much depressed ; the sides are marginate, sensibly 

 constricted at the base ; a slight antemedial elevation gives to the 

 base an apparent transverse depression. Scutellum triangular, pu- 

 bescent, fusco-flavous. Elytra broader than the thorax, robust, sub- 

 parallel, broadly but indistinctly punctate-striate (the striation being 

 almost concealed by the pubescence) ; two circular black spots are 

 situated medially between the second and fifth striae and near the 

 scutellum ; the surface is slightly suffused with fuscous. Antenna? 

 long, robust ; the third to the fifth joints long and slender, sixth to 

 ninth dilated ; first to fifth flavo-testaceous, sixth to ninth black, 

 tenth and eleventh rufo-testaceous. Legs tolerably robust. 



0. binotatus differs from all the species (known to me) to which it 

 seems nearly allied, by the elongated (instead of transverse) form of 

 its tliorax. 



From the neighbourhood of Bahia. A single example is in tho 

 collection of the Rev. H. Clark. 



16. Omototus humero-notatus. 



0. oblongo-ovatus, testaceo-pubescens, Jfavus; capite inter ocidos 

 obsolete foveolato ; thorace transverso,ad latera rectilineari ; ehj- 

 tris latis, robustis, punctato-striatis, testaceo-pubescentibus, ad 

 scutellum duce maculae circidares apparent, fusco suffusce ; an- 

 tennis sat robustis, ad apicem subdilatatis, art. 1-5 Jlavis, 6-11 

 fuscis ; pedibus Jlavis, posticis sidyelongatis. 



Long. corp. 2 lin., lat. 1 lin. 



Oblong-ovate, testaceo -pubescent, flavous. Head short, trans- 

 verse, hardly elongated ; above the labrum is a transverse triangular 

 depression, and above the base of the antennae between the eyes 

 is an obsolete fovea in the form of the letter Y : the eyes are large, 

 situated at the base of tho head, and extending laterally as far as 

 the anterior angles of the thorax. Thorax transverse, rectangular ;
