90 AMERICAN ENTOMOLOGY. 



Enoplium damicorne. — Specific character. Black ; thorax 

 rufous, slightly edged with black. 



Tillus damicornis Fabr., Syst. Eleut. i. p. 282. 



E. thoracicum nobis, Journ. Acad. Nat. Sciences. 



Desc. Body black, hairy, punctured, cylindrical : antennae with 

 the terminal joint narrowed near the tip on the inner side : thorax 

 rufous, lateral and posterior edges black : pectus rufous : elytra 

 black with a slight purplish tinge, immaculate ; punctures large? 

 profound, approximate, and behind the middle small, confluent. 



Ohs. This insect is an inhabitant of the greater part of the 

 Union. I have obtained specimens in Missouri. In my account 

 of the species as above quoted, I made the following remark : '' I 

 should consider it the same as the Tillus daTnicornis of Fabr. but 

 that, in the description of that insect, the author mentions but 

 two dilated joints of the antennae, whereas in ours there are three 

 dilated joints." Notwithstanding this remark, it agrees with it 

 so well in other respects, that on further consideration, I think 

 we may safely refer it to the damicorne, and admit that Fabri- 

 cius was mistaken in the number of dilated joints. Latreille, in 

 his Histoire Naturelle, &c. abserves, that " Le tille damicorne de 

 Fabricius differe peu, or presque point de cette espfece, (^E. Weheri) 

 a en juger par les phrases sp^cifiques."

Enoplium quadripunctatum. — Specific character. Black . 

 elytra sanguineous, with four black dots. 



E. -i-jmnctatum nobis, Journ. Acad. Nat. Sci., iii. p. 188. 



Desc. Body black, somewhat hairy, punctured : thorax de- 

 pressed, subquadrate, not contracted behind; angles rounded, 

 punctures confluent each side : scutel black : elytra sanguineous, 

 each with two black, orbicular, subequal dots, one before, and 

 the other behind the middle. 



Ohs. This species is subject to vary in the size of the spots on 

 its elytra, those of some specimens which I obtained in Arkan- 

 saw, being much larger than I have ever observed them on those 

 of this State.
