106 Mr. H.W. Bates on the Endornychidic of the Amazon Valley. 



in that country to obtain a sufficient number of specimens. I think 

 it likely the following is also another variety of this species. 



7. Corynomahts awratus, n. sp. 



G rufo-ferrugineus, an tennis, articulis duobus basalibus exceptis, tibiisque 

 nigris; thorace pone medium paulo ampliato ; elytris ovatis, fortisaime 



rugoso-punctatis, interstitiis subtiliter punctulatis, auratis nitidiaaimia 

 apieibus flavo-rufis. — Long. lin. 4-J (d"). 



Head and prothorax shining-, sparingly punctured ; the sides of the 

 latter gradually widened after the middle, rounded and narrowed to the 

 apex, the fore-angles rounded. Elytra slightly widened from the 

 shoulders to one-fourth the length, then slightly narrowed to two- 

 thirds the length, afterwards gradually narrowed to the apex, the con- 

 vexity regular and moderate; they are covered with large punctures, 

 which are everywhere connected in groups by ruga); the interstices 

 convex, highly polished, very finely and sparingly punctured, brilliant 

 golden, the apex only with a yellowish-red spot. ' Beneath, the body 

 and legs shining red ; the tibia), except their apices, black ; the under- 

 margins of the elytra brassy, coarsely punctured. 



The middle tibiae of the male in this species are strongly bowed, 

 with the usual emargination on the inner side near the apex very 

 large. I captured only one individual of this remarkably beautiful 

 form, at St. Paulo, in company with the two preceding. 



8. Corynomahts Gerstaeckeri, n. sp. 

 C. rufo-ferrugineus, antennarum articulis 4-8 elongatis, clava nigra ; pro- 

 thoracis lateribus apud medium fere rectis, angidis anticis prominulis ; 

 elytris subovatis, mediocriter punctatis, interstitiis subtiliter punctulatis, 

 nigro-cyaneis, margine omui, sutura fasciisque duabus, post medium 

 linea angusta in medio connexis, rufo-ferrugineis. — Long. lin. 4} ( <$ ). 



Head and thorax shining, thickly and finely punctured. Antenna) 

 with the joints 4-8 more elongated than is usual in this genus, red, 

 seventh and eighth joints piceous; club black. Thorax scarcely per- 

 ceptibly widened from the base to near the apex, whence narrowed, 

 the apical angles being produced and subacute. Elytra shaped as in 

 the preceding species, but the convexity much sharper, rising more 

 abruptly from the thorax, moderately punctured, the interstices thickly 

 and finely punctured, blue-black ; the margins and suture narrowly 

 and equally edged with red ; behind the middle are two narrow 

 crooked fascia) of the same breadth and colour as the margins, con- 

 nected together in the middle by a narrower line of the same colour ; 

 the anterior fascia is a little behind the middle, the posterior midway 

 between it and the apex. Body beneath and legs ferruginous, shining ; 

 under-margins of the elytra yellow, punctured. 



The middle tibia) in the male are not bowed, the apical notch short
