2. E. MORio F. Herbst. E. Isevigatus F. Herbst. E. piceus 

 Degeer, Turton's Linn. [166] 



This species is subject to vary tbrougli all tbe intermediate 

 gradations between smootli elytra and deeply striated elytra; 

 which is the cause why several species have been made of it. 

 The lateral edge of the thorax is grooved. 



[Belongs to the genus Melanactes Lee. — Leg.] 



3. E. ABRUPTUS nob., Ann. Lye. Nat. Hist. New York. Like 

 morio, but more convex above, more impressed at the junction 

 of the thorax and abdomen ; more densely and minutely punc- 

 tured ; a little more robust; each joint of the antennae originates 

 much nearer the posterior angle of the preceding joint; and the 

 lateral edge of the thorax is destitute of a groove, of a somewhat 

 different form, and the head is not impressed, but is rounded on 

 the front. 



[Belongs to Ludius, ante 1, 390. — Leg.] 



4. E. ATTENUATUS. — Reddish brown; elytra somewhat atten- 

 uated, blackish and mucronate behind. 



Lahabits the United States. 



Body bright reddish-brown, almost sanguineous, with small 

 close set punctures : head not indented before : antennae, joints 

 not elongated : thorax convex, lateral margin arcuated ; naiTowed 

 before ; line from the posterior angle rectilinear, acute, diverging 

 from the lateral edge so as to be as near to the inner edge : 

 region of the scutel rather widely indented : elytra with smaller 

 punctui'es than those of the thorax; with obsolete striae; termi- 

 nal oblique third black ; tip somewhat attenuated and mucronate : 

 feet a little darker. 



Length four-fifths of an inch. 



A variety occurs of which the elytra are obscure, but still the 

 terminal third, and the exterior margin also, are black. In a 

 particular light is a slight. sericeous effect. 



[Also a Ludius, ante 1, 392. — Leg.] 



5. E. VIRIDIPILIS nob. — The thorax in form resembles those 

 oculatus and mi/ops F. but is proportionally longer. 



The posterior angles are curved considerably downward. It 

 is rare. 



[A species of Chalcolepidius. — Leg.]
