ARTICULATES : INSECTS. 



Cockroach, B. orientalis.

Fig- 341- 



BLATTARLE, Latr., OR COCKROACH FAMILY. This 

 Fig. 340. Family contains orthopterous insects 



which have the body oval, flattened, 

 the hind extremity of the abdomen 

 furnished with the conical articulated 

 appendages, and the antennae long 

 and many-jointed. Cockroaches are 

 nocturnal, and are found not only in 

 forests, but some species infest kitch- 

 ens, store-rooms, and closets, devour- 

 ing all kinds of provisions, and even 

 fabrics. The Genus Blatta contains 

 the species, of which we have several 

 that are indigenous, and one, B. orien- 

 talis, Linn., which originated in Asia. 

 PHASMIDA, LeacJi, OR WALKING-STICK FAMILY. This 



Family comprises orthoptera which 

 are at once distinguished by their 

 very close resemblance to vegetable 

 structures. Some appear like dry 

 twigs ; others have wings which al- 

 most exactly resemble green or dry 

 leaves. They are sluggish in their 

 movements, and are found princi- 

 pally in warm regions, though sev- 

 eral species belong to temperate 

 climes. Three or more are found 

 in North America. Some of the 

 tropical species are very large, even 

 a foot in length. 



The Genus Diaphomera contains 

 D. fcmorata, Scudd., four inches 

 long, which is one of our most com- 

 mon species. It is the Spectrum 



Walking-stick, D.femorata, fcmOmtUm of Say. 

 Scudd. Reduced one half.
