new species of EumolpidcB. 53 



cato/dorso punctato, fovea trigonatd leevi, male definita, 

 leviter impresso. 



Long. 6^ — 8 lin. 



Hab. — Cayenne. 



Head finely granulose, subnitidous, impressed with 

 small but distinct round punctures ; clypeus elongate and 

 wedge-shaped in the $, broader and less distinctly 

 cuneiform in the 2, its apical margin broadly obsolete in 

 both sexes ; jaWs and labrum nigro-piceous ; front im- 

 pressed with a shallow fovea^ from which the faint traces 

 of a longitudinal groove extend upwards to the vertex; 

 antennae slender, the third and fifth joints equal in length, 

 each distinctly longer than the fourth ; five upper joints 

 not thickened in the $ , very slightly so in the § . Thorax 

 nearly twice as broad as long; sides rounded, nearly 

 parallel at the base, converging at the apex, all the angles 

 acute ; upper surface finely grauulose, subnitidous, im- 

 pressed rather closely with shallow round punctures. 

 Scutellum trigonate-ovate, impressed with a few coarse 

 punctures. Elytra much broader than the thorax, 

 narrowly oblong ; sides parallel, the apex subacutely 

 rounded ; above convex, faintly excavated below the scu- 

 tellum, the humeral callus prominent; surface coarsely 

 and rather closely punctured; interspaces nitidous, minutely 

 punctured, impressed with irregular strig^. 



£J. speciosus is closely allied to the preceding E. im- 

 perialis ; the $ is separated by the difference in the abdo- 

 minal segment and by the slender antennse, as well as by 

 the entirely different telum; it is separated from E. Batesii 

 by the same character, and by the more parallel sides of 

 the thorax ; the narrower and more parallel form of the ? 

 will distinguish it from the same sex of either species. 



Eumolpus Batesii. 



Elongato-ovatus, convexus, metallico-cferuleus, nitidus, 

 subtus viridi-micans, antennis extrorsum nigris ; thorace 

 latitudine duplo latiori, lateribus rotundatis, basi et ajiice 

 convergentibus, subnitido, tenuiter punctato, interstitiis 

 gramdosis ; elytris granulosis, distincte punctatis, inter- 

 spatiis hie illic leviter et irregulariter strigosis ; prosterno 

 longitudini postice asquilato, ad apiccm ampliato, margine 

 postico leviter cmarginato, angulis posticis obtusis ; meso- 

 sterno latitudine longiori, apice trilobato, lobis latcralibus 

 parvis s£epe indistinctis, lobo apicali brevi, late trimcato ;
