282 INVERTEBRATE FAUNA OF SOUTH CAROLINA. 



FAxMlLY CICADELLIDil^]. LEAF HOPPERS. 



This is a family of large extent, and is not well worked up. The com- 

 mon " Grape vine thrips " {Erythroneara vitis Fitch) is a good exam[)le. 

 The Clcadula cxitiosa of Uhler did much damage to winter grain in York, 

 Ahbeville, Union, and Laurens counties, South Carolina, in the sf)ring of 

 1879, and another member of this family, Diedrocephala jiavice}')^ Rilov, 

 was concerned in the same work. 



FAMILY CICADID.E. " LOCUSTS." 



The Seventeen Year Locust (O/cac^a septendecim Linn.) is the best known 

 representa,tive of this family. 



SUB-ORDER HETEROPTERA. 



[Hemiptera havinc; the anterior wings thickened at base, with thinner extremities, 

 which overlap on tiie baclv : Mouth parts inserted at the anterior and inferior portion 

 of the head.] 



This sub-order is one of great extent and includes many of our most 

 injurious insect enemies, as well as many of the most beneficial predatory 

 species. The North American species have been carefully monographed 

 by Mr. P. R. Uhler, of Baltimore, and this inonograph wull probably be 

 published before long as one of the Smithsonian contributions. 



FAMILY REDUVIID^. 



The insects of this family prey upon other insects and may be classed 

 as veiy beneficial to man.
