obtusely sinuoiis; abdomen, termiual and anal segments above 

 punctured. 



Length less tliau lialf an inch. 



This species is closely allied to the ^1. cxnus Say, and its form 

 is perhaps still more like that of an Aiiiara in being more obtuse 

 and robust. It is much larger and more rounded behind. It 

 was taken in Mexico by William Bennett, and was presented to 

 me by Mr. Maclure. 



2. A. BALTIMORIENSIS Say, (Ilarpalus) Trans. Amer. Philos. 

 Soc. 5 Pej. Spec. — A very bad name, as the species is found as 

 well in Indiana as in Baltimore ; but it is a specific name, and 

 therefore unchangeable.

7. A. L.ETUS ? Pej. — An insect is found in this vioinity which 

 I have referred, but very doubtfully, to the hrtus. Its characters 

 correspond to the description, but if it be indeed the same a very 

 important character must be added. My specimen is a male. 

 The alternate interstitial spaces are cupreous, and the remaining 

 part is green. It has a very much dilated, slight indentation 

 behind the middle of the elytra, and a smaller one nearer the tip.
