Cantharolethrus, Thomson, Ann. Soc. Ent. Er. 1862, p. 411. 



Three, perhaps four, closely allied species of this beautiful and peculiar genus of 

 stag-beetles are known, all from Colombia or Ecuador. One of the Colombian species 

 extends its range into the domain of our Fauna, and is remarkable as being, with the 

 exception of two small JEsali, the only form known to inhabit Central America of 

 the conspicuous Family of Lucanidse, so numerously represented in all other tropical 

 and subtropical regions.

Four examples, viz. two males from Costa Rica, and two females from Chiriqui. The 

 largest of the two males measures 50 millim. and one of the females 33 millim. 



The examples obtained by Mr. Champion were both found crawling on tree-trunks, 

 in the dense forest bordering the upper margins of the coffee plantations in the 

 district known as " Las Potrerillas," situate on the south-east slope of the Volcan de 

 Chiriqui.
