 Other citations: "M. testacea Casey," by Blackwelder, 1939, p. 119; 1943,

 Blackwelder (1939).

 Discussion : Kraatz, included the first group of Leptacinus as of Erichson, 

 1839b, p. 334, where two species are described. However, in the text one 

 of these species is eliminated, leaving the new genus monobasic.
