the United States; and one of our native species, Stagmomdntis 



Fig. 297. — Stagmomantis Carolina 



Carolina (Fig. 297), is found as far north as Maryland 

 and southern Indiana. 



Recently two exotic species have been introduced 

 into the Northern States, probably by the irnporta- 

 tion of oothecce on nursery stock, and have become 

 established here. These are the Mantis religidsa of 

 Europe, which was first observed in this country 

 near Rochester, N. Y., in 1899, and Paratenodera 

 sinensis of China and Japan, which was first ob- 

 served here at Philadelphia about 1895. 



Family BLATTID^E* 



The Cockroaches 



The cockroaches are such well-known insects that 

 there is but little need for a detailed account of their 

 characteristics. As already indicated in the table of 

 families, the body is oval and depressed; the head is 

 nearly horizontal, and wholly or almost wholly 

 withdrawn beneath the pronotum; the head is bent 

 so that the mouth-parts project caudad between 

 the bases of the first pair of legs; the antennas are 

 long and bristle-like; and the pronotum is shield-like. 

 This family includes only the cockroaches ; but these Fig. 298. — Egg- 

 insects are known in some localities as "black ^^^^^ °f. ^^^^'

*This family is separated from the Orthoptera by Handlirsch ('o6-'o8) and 

 made to constitute a distinct order, the Blattoidea.
