EARLY RECORDS OF THE SPECIES. 



This species was originally described by Fabricius in 1775 and 

 the type specimen or specimens were from Virginia. The specie.s 

 was given space under the genus Carabus in this author's other 

 writings on Coleoptera until 1801, when he placed it in the genus 

 Calosoma. This species attracted the attention of other early and 

 prominent writers like Olivier, Latreille, Say, and Dejean. Chapuis 

 and Candeze in 1855 were the first authors to figure and describe the 

 larva. Riley, between 1870 and 1880, frequently wrote of the useful- 

 ness of this species as an enemy of the forest tent caterpillar ( Mala- 

 cosoma disstria) and cankerworms. Numerous other entomologists 

 of the United States, Canada, and even some of those of European 

 countries, have collected and pubUshed many valuable notes on this 

 important economic species. 



DISTRIBUTION. 



This species occurs in Alabama, California, Colorado, Connecti- 

 cut, Delaware, District of Columbia, Florida, Georgia, Illinois, 

 Indiana, Iowa, Kansas, Kentucky, Maryland, Massachusetts, Michi- 

 gan, Mississippi, Missouri, Nebraska, New Jersey, New York, North 

 Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, 

 Texas, and Virginia. It has also been found in Ontario, Canada, and 

 in Mexico.
