two small spots, tip and humerus testaceous : the thoracic vittae 

 are sometimes reduced to very small spots : scutel always testa- 

 ceous. 



[Also a 3Ionocrej)uUus. — Lec] 



46. PI CIRCUMSCRIPTUS Germ. — The penultimate tarsal joint 

 is at least half the length of the last, and is produced beneath 

 into a lobe. 



[Nothing of the kind exists in the species that I consider as Ger- 

 mar's, and which that author places in Cryptohypnus : for me it is a 

 3Ionocre]iidius, without tarsal lobes. What insect Say had in 

 view, I am unable to determine. — Lec] 



46. E. BISECTUS nob. (Journ. Acad. Nat. Sc.) — Penultimate 

 tarsal joint remarkably short above, hardly visible, but produced 

 beneath into a dilated lobe, two-thirds the length of the ultimate 

 joint. [Ante, 113.] 



48. E. EXTRIATUS nob. — This is the E. geminatus nob. (Ann. 

 Lye. N. Y.) Elytra destitute of stride; joints of the tarsi, ex- 

 cepting the terminal one, with dilated lobes beneath. I change 

 the name, as that of geminatus was previously given by Germar 

 to a Brazilian species. 



[Belongs to Lissomus. — Leg.] 



49. E. BELLUS S. (Journ. Acad. Nat. Se. iii. p. 168.)— The 

 penultimate tarsal joint is dilated beneath into a lobe. A very 

 pretty little species. 



50. E. BiNUS. — Black ; with two large testaceous spots on 

 each elytron. 



Inhabits Indiana. 



Body black, with short yellowish hairs, almost sericeous, punc- 

 tured : elypeus rounded at tip, somewhat prominent : antennae 

 scarcely serrate, rufous ; second joint more than half as long as 

 the third; terminal joint [178] not, or hardly longer than the 

 penultimate one : thorax on the lateral edge rectilinear from be- 

 fore the middle to the tip of the posterior spine, which is rather 

 long, acute, carinate : scutel black : elytra with punctured striae, 

 and minutely punctured interstitial lines ; on each a large testa- 

 ceous spot, extending from the base nearly to the middle, not 

 reaching the suture, and a smaller one beyond the middle : pec-
