new species of EumolpidcB. 49 



finely grannlose, subniticloiis, impressed rather closely with 

 fine but distinct punctures. Scutellum semioblong-ovate, 

 its apex rounded ; svirface smooth, impressed near the apex 

 with a deep fovea. Elytra rather broader than the thorax, 

 sides parallel, slightly converging near the apex in the $ ; 

 above convex, distinctly punctured, interspaces finely but 

 not closely punctured, impressed here and there with fine 

 irregular strigge ; humeral callus moderately thickened, 

 very obtuse. Legs robust. 



The $ of this species may be distinguished from E. 

 Ignitus by its broader thorax, the different shape of the 

 abdominal fovea, and by the difference in the form of the 

 telum; the same characters, with the addition of the 

 closer punctuation of its upper surface, separate it from 

 E. Surinam ensis ; the $ is at once distinguished fi'om 

 either by the emarginate apex of the last abdominal seg- 

 ment.
