2 MISC. PUBLICATION 470, U. S. DEPT. OF AGRICULTURE 



Owing to the close resemblance to one another of many of the species, 

 the published records on distribution and host plants are in the con- 

 siderable part incorrect, and the species are badly confused in most 

 collections. Clearing this confusion will materially aid those con- 

 cerned with the control of economically important species. 



The types, or specimens compared with the types, have been 

 examined of all the described species found in North America except 

 those that have been lost or are deposited in European collections. 

 Seven species of Actenodes and 115 species of Chrysobothris are 

 treated in this publication, of which 7 species are described as new. 

 Four fossil species and 3 other species, which are unrecognized or 

 listed as Chrysobothris but belong to other genera, are omitted from 

 the key, but these are briefly treated at the end of the publication. 

 Owing to the great variation in the size of the beetles in the tribe 

 Chrysobothrini, the drawings were made to the same scale.

Linnaeus (10, p. 408) established the genus Buprestis on 19 species, 

 of which ohrysostigma is No. 7. This genus remained undivided 

 until Fabricius (5, p. 218) established the genus Trachys for 11 

 species. Up to 1800 there were at least 250 species described in the 

 genus Buprestis, besides 43 species of Carabus and Cicindela placed 

 by Geoffroy (6, p. 141) hi that genus. 



Geoffroy (6, p. 123) , not liking the name used by Linnaeus, pro- 

 posed Cucujus for Buprestis and included 6 species, of which 

 chrysostigma (Linnaeus No. 7) is the first, and used the name 

 Buprestis for Carabus and Cicindela of Linnaeus, including 43 

 species, some of which were unnamed, although these were given 

 names by Fourcroy in 1785. 



Latreille (9, p. 1$®) designated Buprestis chrysostigma Fabricius 

 1775 (who cited chrysostigma Linnaeus 1758) as the type of 

 Buprestis. 



Eschscholtz (4, p. 9) established the genus Ch^rysobotris (original 

 spelling), including Buprestis impressa, B. chrysostigma, and B. 

 a finis, all congeneric, and the genus Anoylochira, including B. 

 flavomaculata, B. strigosa, B. 8-guttata, B. punctata, B. cupreus, B. 

 haemorrhoidalis, and B. rustica. 



Gistel (7, p. 10) established the genus Amblis and included 

 Buprestis chrysostigma F., B. affinis F., and B. nobilis (?) F.
