In 1839, Serville discussed three supposed species of the 

 genus from the West Indies, describing two of these as new, 

 but stating that all might be varieties of discoidalis (in which 

 remark B. dubia was included, that species now standing as 

 genotype of Blaptica). It is evident that all of his West In- 

 dian material, except the female of his varians, represents mere 

 color variations of the same species. 



In 1864, Saussure described B. cubensis briefly, later in the 

 same year discussing the insect more fully, comparing it with 

 his mexicana (~ B. colosscits, see page 291), but evidently 

 overlooking Serville's discoidalis and confusing that author's 

 atropos and varians with atropos of Stoll. His species is 

 clearly a synonym of discoidalis and later, with Zehntner, he
