Enchophora guttata, White, Ann. & Mag. Nat. Hist. 1846, xvii. p. 331".

Hab. Muxtco, Jalapa (Hoge); Guaremata, San Isidro (Champion); Panama, Bugaba, 
Tolé (Champion). 
White gave the somewhat vague locality “South America”, a habitat in any case 
too loose for any scientific purpose, and, in this instance, possibly erroneous.
