A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 7 



punctate, and longitudinally carinate basally. Prosternum coarsely, densely, 

 deeply punctate, slightly rugose anteriorly, glabrous, and gibbose on each side 

 along anterior margin, which is truncate. Anterior and middle tibiae with a 

 number of very small teeth on their inner margins, the former arcuate and 

 slightly expanded near apex. 

 Length 14 mm., width 6.5 mm. 



Redescribed (except for the antennae, which are missing) from 

 the male type of bella, No. 2710, in the Museum of Comparative 

 Zoology, Cambridge, Mass. 



Female. — There are scarcely any external differences between the sexes 

 of this species, but the females are usually more robust, the last visible abdomi- 

 nal sternite is more transversely sinuate at the apex, and the tibiae are un- 

 armed on their inner margins. 



Type locality. — Of auronotata, "Cuba" ; type supposed to be in the 

 collection of Rene Oberthiir. Of bella, Liberty County, Ga. ; type in 

 the Museum of Comparative Zoology (simply labeled with an orange 

 disk). 



DISTRIBUTION 



From material examined: 



Florida: Lake Worth, June 4, 1887; Biscayne, May 27 (Hubbard and Schwarz). 



Fort Capron, April 1887; Marathron, March 8, 1919 (E. A. Schwarz). 



Orlando, July 15, 1927 (O. 0. McBride). Gainesville, 1915. Orange County, 



June 17 (C. Nelson). 

 Georgia: Savannah (Hubbard and Schwarz). Liberty County. 

 Cuba: Throughout the island. 



Also recorded in the literature by Champlain and Knull (1922) 

 from Paradise Key, Fla., and by Chamberlin (1926) from Key West, 

 Miami, and Elliott Key, Fla., and Tybee Island, Ga. 



Hosts. — Champlain and Knull (1922) record an adult cut from 

 dead baldcypress (Taxodium distichum (Linnaeus) Richard), and 

 state that the adults were abundant on fire-killed "Lysiloma lati- 

 siliqua" at Paradise Key, Fla. Specimens in the collection are labeled 

 as taken from the dry wood of "Cajanus indicus" by O. C. McBride 

 at Orlando, Fla. 



Very little variation was observed in the examples examined except 

 in size, the length ranging from 10 to 15 mm. 



This species is closely allied to bellula Mannerheim found in Santo 

 Domingo, and the name is confused in the literature with that 

 species, but bellula differs from auronotata in having the elytra more 

 acuminate posteriorly, the surface more finely punctured, with the 

 four discal spots distinctly embossed, brighter green, and narrowly 

 margined with a golden-cupreous color. 



Dejean (1833 and 1836) lists oellula from Cuba with bellula var. 

 sobrina Mannerheim from Santo Domingo as a synonym, without 

 giving any description. Actenodes bellula var. sobrina as used by 

 Dejean is a manuscript name, but Mannerheim (1837), under the 

 name of bellula, gives a description of the A. bellula var. sobrina 

 Mannerheim listed by Dejean in his catalogues from the island of 

 Santo Domingo, and writes, "Not possessing the real Actenodes 

 bellula Dejean, I have been obliged to describe the variety." Since 

 no description had been published under the name bellula, this name 

 must be applied to the species described by Mannerheim from Santo 

 Domingo, and sobrina Mannerheim must be placed as a synonym of 

 that species. Castelnau and Gory (1837) described the species listed
