Like Megathopa an exclusively American genus, extending in the north to the 41st 

 parallel of latitude and to about the same distance from the equator in the south, the 

 species being most numerous and varied in the equatorial subzone. 135 species have 

 been described. 



l. Canthon saUaei. (Tab. II. fig. 2.) 



Canthon sallei, Harold, Ann. Soc. Ent. Pr. 1863, p. 174 l ; Berl. ent. Zeitschr. 1868, p. 39 2 . 



Hab. Nicaeagua, Granada 1 {Salle), Chontales {Belt, Janson) ; Costa Rica ( Van 

 Patten); Panama {Boncar d), Tab oga Island {Champion). — South Ameeica, Colombia 2 . 



Two Nicaraguan examples in the Salle collection are labelled " type " : these agree 

 in colour with Harold's original description of the species, but not with the subsequent 

 one given in his 'Monograph.' The species seems to be represented in Nicaragua by 

 one constant varietal form, in which the upper surface is shining testaceous-red, with 

 the head, a narrow basal margin to the thorax and elytra, and the suture of the latter, 

 dark brassy ; the under surface and legs brassy-black, with the abdomen (except its 

 basal and apical margins) and pygidium testaceous-red. In Costa Eica the local form 

 is similar, except that the thorax has a broad brassy-black central vitta (sometimes 

 interrupted in the middle), and the basal and sutural brassy-black borders of the elytra 

 are more or less (sometimes very greatly) dilated. Examples from Panama and Taboga 

 Island again differ, the thoracic vitta being narrower and dilated in the middle, the 

 abdomen wholly black, except the pygidium (which is yellow with a dark central line), 

 and the hind (and sometimes also the middle) femora testaceous-yellow in the middle. 



In the form or forms described by Von Harold in his ' Monograph/ who, according to 

 his habit, does not say to which of the numerous localities they refer, the colours are 

 *« piceus, thorace leviter virescente maculis quatuor in angulis dispositis testaceis, vel 

 omnino piceo vel rufo, elytris nigris interdum rufo-signatis." 



A Nicaraguan specimen is figured.
