 Eab. Mexico 1 ; Guatemala, Cubilguitz, Teleman (Champion). 



3. Canthon spinosus. 



Canthon spinosus, Harold, Ann. Soc. Ent. Fr. 1863, p. 174 l ; Berl. ent. Zeitschr. 1868, p. 42 2 . 

 Eab. Mexico, Toxpam (Salle 1 ), South Mexico 2 . 



Von Harold described this species originally from specimens taken by Salle at 

 Toxpam, and subsequently redescribed it from examples from Southern Mexico in 

 Bonvouloir's collection. In the Salle collection there are no specimens from Toxpam, 

 and those labelled C. spinosus (from Tuxtla, Playa Vicente, and Cordova) seem to agree 

 better with the description of C. speciosus than with that of C. spinosus. One, however, 

 from Sturm's collection, seems to be intermediate between the two species ; so that it is 

 possible they form really only one. It is to be remarked that Von Harold described 

 his C. speciosus at a subsequent date, when he appears not to have had the type 

 specimens of his original C. spinosus before him.

 The typical form as described and figured by Latreille alone occurs in our Fauna. 



5. Canthon moniliatus. (Tab. II. fig. 3.) 



O. rufulo affinis, late ovatus, subnitidus, elytris castaneis utrinque striis octo distanter et eleganter punctulatis ; 

 capite seneo, clypeo bidentato et prope dentes utrinque breviter recte truncato ; tborace flavo-testaceo, 

 medio juxta margines anticum et posticum asneo plagiato; subtus pedibusque nigro-nitidis, femoribus 

 medio albo-testaeeis. 



Long. 6-7 millim. 



Hab. Panama, Bugaba (Champion). 



Var. Tborax flavus, macula unica nigro-aanea juxta marginem posteriorem. 



Eab. Nicaeagua, Granada (Salle). 



Belongs to the C. triangularis group, and the subgroup C. rufulus, in which the sides 

 of the prosternum are without transverse carina and the hind femora ungrooved near 

 their anterior edge. The thorax is rather strongly but obtusely angulated in the middle 

 of its sides, and the seventh and eighth elytral striae are obliterated on the humeral 

 callus. The pygidium is dull reddish, opaque, and faintly carinated down the middle. 

 The legs are blackish or castaneous, with the middle (and greater part) of the femora
