nexo species of Eumolpidce. 51 



extensa, medio vitta elevata separata, projfunde impresso ; 

 telo brevi, abrupte curvato, apice obtuse truncato, medio 

 dente brevissimo arraato. 



Fcem. — Abdominis segmento ultimo apice integro, ob- 

 tuse rotimdato. 



Long. 5 — 62 lin. 



Hab. — Cordova, Pampas of Peru. 



Head finely but not closely punctured, impressed here 

 and there with coarse punctures, which are scattered irre- 

 gularly on the surface ; clypeus subquadrate, its sides 

 nearly parallel, its apical margin entirely obsolete ; antennse 

 moderately robust, five outer joints slightly thickened, third 

 joint distinctly longer than the fourth in the $ ; the two 

 joints nearly equal in length in the 9 . Thorax about one- 

 half broader than long; sides straight and nearly parallel 

 from the base to the middle, thence rounded and converging 

 to the apex, all the angles acute ; above convex, distinctly 

 punctiu-ed, interspaces minutely punctured. ScuteUum 

 narrow, subcuneiform, its surface nitidous, minutely punc- 

 tured. Elytra much broader than the thorax, the sides 

 parallel, the apex subacutely rounded in the $ ; above 

 convex, rather coarsely but not very closely punctured, 

 interspaces minutely punctured, impressed with a few 

 irregular strigse ; humeral callus prominent, humeral angle 

 tinged with aureous. 



The narrow convex thorax is the principal character 

 separating the ? of the present species from E. surina- 

 mensis ; the same character, together with the difference 

 in the abdominal fovea and the shorter telum, separates 

 the $ fi-om the same sex of that insect.
