a longitudinal indentation in the middle, and a slender impunc- 

 tured line extends to the anterior edge : elytra striate, the striae 

 not very obviously punctured, third and fourth confluent before 

 the tip ; greatest breadth posterior to the middle : tibiffi and 

 tarsi rufous. 



Length two-fifths of an inch. 



This species was sent to me by Dr. Harris. The particular 

 disposition of the hair on the elytra of the specimen gives the 

 appearance of a broad band at base, another beyond the middle, 

 and a subsutural spot in the middle, blackish.

24. E. ARMUS. — Black ; shoulder rufous. 

 Inhabits United States. 



Body black : clypeus with large punctures, somewhat triangu- 

 larly depressed, anterior edge obtusely arcuated, distinct from the 

 anterior part of the head : antennas, joints as broad at tip as long, 

 second and third equal, terminal one large ovate acute, not ab- 

 ruptly 'smaller towards the tip : thorax convex ; punctures rather 

 distant, larger before ; lateral edge subrectilinear, a little undu- 

 lated ; posterior angles short, their exterior edge very much ar- 

 cuated, so that the tip points inward and backward, carina di-

 with punctured striae, third and fourth confluent before the tip ; 

 interstitial spaces punctured ; humerus rufous. 



Length one-fourth of an inch. 



Different from scapularis S., of which the tarsi are lobed. It 

 inhabits the Middle States, and Dr. Harris sent me one from 

 Massachusetts. 



[This is the type of Gamhrinus Lee. Trans. Am. Phil. Soc. 

 10, 435 ; it is united with Limonius by Lacordaire. — Lec] 



25. E. AGONUS. — Posterior thoracic angles very short and 

 rounded; antennae longer than the thorax. 



Inhabits Massachusetts, Harris. Pennsylvania. 



Body violaceous-blackish : clypeus very obtuse before and 

 hardly distinct from the anterior part of the head ; punctures
