Varies in size from 7 to 12 millim. ; in colour from brilliant brassy-green and golden- 

 coppery to bluish-green, violet, and deep black. In northerly localities the elytra are 

 much less glossy. A small rotundate ovate form, with pygidium only slightly convex 

 even in the male (C. chloris, Salle coll.) occurs in various localities in Mexico. 



25. Canthon mutabtLis. (Tab. II. fig. 11, var.) 



Canthon mutabile, Lucas, in Voy. de Castelnau, Zool. iii. p. 100 \ 

 Canthon mutabilis, Harold, Berl. ent. Zeitschr. 1868, p. 127 2 . 



Rah. Panama, Bugaba, Volcan de Chiriqui, Tole (Champion). — South Ameeica 2 , 

 Colombia 2 , Amazons 1 2 , La Plata 2 . 



The Panama examples form a local variety of the species similar to the var. trans' 

 versalis described by Von Harold, but differing in the bright brassy-green head and thorax. 

 In Colombia the local form is similar, with the exception of having a brassy-black 

 head and thorax. Some examples from the Lower Amazons are like the Colombian 

 form, but they are there mingled with a great diversity of colour-variations. 



An example from Tole is figured. 



26. Canthon deyrollei. 



Canthon deyrollei, Harold, Berl. ent. Zeitschr. 1868, p. 132 \ 



Hab. Beitish Hondueas, E. Sarstoon (Blancaneaux) ; Guatemala, San Geronimo 

 (Champion) ; Nicaragua, Chontales (Belt). 



The locality of the species was unknown to Von Harold 1 . C. deyrollei strongly 

 resembles the blue-black colour-variety of C. ehevrolati, from which its pluridentate 

 clypeus at once distinguishes it. 



27. Canthon chlorizans. 



Obscure viridi-metallicus, nitidus, pedibus rufo-testaceis ; capite tboraceque sat crebre sed discrete punctatis ; 

 clypeo Eequaliter quadri-dentato, sutura genarum baud dentata ; elytris sat acute simpliciter striatis, inter- 

 stitiis disperse punctulatis, bumeris baud cariuulatis ; pygidio parum convexo, puuctato, medio prope basin 

 obtuse carinato ; corpore subtus nigro, subopaco ; tibiis posticis subrectis baud dilatatis. 



J 1 . Tibiarum antiearum calcar apice lato bifido. 



Long. 5 minim. 



Hah. Mexico, Juquila (Edge). 



A little more oblong, and with the elytra relatively longer, than C. viridis.
