The Blattid/i: of Indiana By W. S. Blatchley, Terre Haute, Ind. 



The members of the family Blattidse, commonly known as cockroaches, 

 are classed among the Orthopterahy reason of their biting mouth parts, and 

 direct or incomplete metamorphosis. From the other families of that 

 order the Blaitida may be known by their depressed, oval form; their nearly

 tarsi ; and by the absence of either ovipositor or forcipate appendages at the 

 end of the abdomen.
