published. In his third edition of the same work (1836), he gives 

 in addition to the ones mentioned previously, viridifasciata, calca- 

 rata, and chalyheitarsis, all from Mexico and credited to Chevrolat, 

 of which virldifasciata is only a manuscript name, and which was 

 later described by Castelnau and Gory as regularis. Lacordaire 

 (1857) published a description of the genus, and in which he placed 

 a number of species, some of which were previously included in this 

 genus by Dejean. 



Actenodes is a rather large genus and has a wide distribution, the 

 species being distributed throughout North, South, and Central 

 America, Mexico, West Indies, and Africa. It is closely allied to 

 Chrysohothris and Golohogaster, but can be easily distinguished 

 from either of these two genera by the third joint of the tarsi 

 having two long spines, which extend beyond the fourth joint.

ACTENODES MARMORATA (Castelnau and Gory) 



Chrysohothris marmorta Castelnau and Goby, Mon. Bupr., vol. 2, 1836, 

 pp. 31-32, pi. 6, fig. 45. 



The following is a translation of the original description : 



Dark aeneous; thorax with three not very deep foveae; elytra 

 cupreous, and marbled violaceous. Length, 9 lines; width, 3% lines. 

 Habitat Martinique. 



Cupreous, with a feebly darker tinge. Head granulose, with a 

 deep longitudinal groove at the middle, and two elevations between 

 the eyes. Thorax transverse, with an impression at middle behind, 

 and also one on each side, surface covered with small transverse 

 rugae. Elytra granulose, with longitudinal costae, and ornated with 

 an irregular blackish-violet spot at the base, and three irregular 

 oblique sinuate fasciae of the same color, the posterior one situated 

 at the apex. Body beneath and legs punctate and of a beautiful 

 cupreous color. Tarsi violaceous. 



This is certainly closely allied to fulTninata Schonherr, but ac- 

 cording to the description given by Castelnau and Gory it is a larger
