in having the elytra banded, the base of these wing-sheaths is 

 not turgid, as in that species. I obtained a specimen in East 

 Florida, when in that country with Mr. Maclure's party. 



[The name being preoccupied, this was afterwards named by ' 

 Ferte A. hizonatus; it does not, however, appear different from 

 his A. cervimis. — Lec] 



3. A. PALLIDUS. — Pale; elytra with a broad band and narrow 

 suture, blackish. 



Head and thorax pale ochreous ; the latter with a moderate 

 longitudinal groove, and gradually narrowed towards the base ; 

 the lateral curvature behind the middle being somewhat concave : 

 elytra pale yellowish ; basal margin dusky ; a dilated blackish 

 band on the middle much dilated on the exterior margin, and at 

 the suture ; on both of which, it extends in a narrow line to the 

 base and tip; punctures not distinct; beneath pale rufous; feet 

 whitish. 



Length one-tenth of an inch. 



This may be distinguished by its thoracic groove, pale color, 

 single band, and marginal lines.

4. A. POLiTUS. — Blackish ; thorax not narrowed behind ; ely- 

 tra bright rufous. [246] 



Body with rather long hairs : head blackish : antennae dull 

 rufous : thorax blackish, rather short, not obviously narrowed 

 behind ; a transverse impressed line at base : elytra impunctured, 

 polished, rounded, bright rufous, at the somewhat pointed and 

 blackish : feet bright rufous. 



Length more than one-twentieth of an inch. 



The form of the thorax and elytra of this species are quite 

 different from those of the preceding species. 



[I have failed to identify this insect.. — Lec] 



5. A. LUGUBRis. — Black, impunctured ; two basal joints of the 

 antennae and mouth rufous. 



Inhabits Missouri. 



Body black, impunctured, slightly hairy : head polished : an- 

 tennae a little serrate, two basal joints obscure rufous : mouth ob- 

 solete piceous : thorax polished, transversely oval, orbicular, a
