new species of EumolpidcE. 56 



Foem. — Abdominis segmento ultimo utrinque sinuato, 

 medio pauUo producto, rotundato-ovato ; dorso loavi, im- 

 pimctato. 



Long. 7^ — 8^ lin. 



Hab. — Amazon. 



Head granulose, sparingly punctured; vertex and front 

 impressed mth a fine longitudinal groove ; cljpeus broadly 

 wedge-shaped, its apex broadly obsolete; antennae slender, 

 five upper joints not distinctly thickened, third joint 

 rather longer than the fourth. Thorax twice as broad as 

 long; sides rounded, converging at base and apex, hinder 

 angles armed with an obtuse tubercle ; upper surface 

 granulose, impressed, but not very closely, with fine round 

 punctures. Scutellum semiovate, impressed near the apex 

 Avith a deep fovea, this latter sometimes obsolete. Elytra 

 oblong, sides parallel, the apex subacutely rounded ; upper 

 surface convex, obsoletely excavated near the scutellum, 

 granulose, rather closely punctured ; below the humeral 

 callus, occupying the middle third of the elytron, is a 

 raised longitudinal vitta, the apex of which is bent 

 inwardly towards the suture ; on the disk of each elytron 

 are also several faint longitudinal costte, only visible in 

 a certain light. Legs slender, apices of tibiae unarmed. 



This species, of Avhich I only possess three individuals, 

 all 2, closely resembles the ? oi E.Batesii; it may at once 

 be known by the different form of the apical segment of 

 the abdomen, and also by its larger size.
