 mon in eastern half of state. Taken from clover and weeds. 



Tettigoniella hieroglyphica Say. var. confiuens Uhler. Taken 

 with the above variety. 



Diedrocephala coccinea Forst. Very generally distributed. 

 Common but not in great numbers. Injurious to many 

 ornamental plants in the Missouri Botanical Gardens at 

 St. Louis. Nymphal cast shins observed on leaves of 

 Magnolia and American Holly. Adults taken from several 

 kinds of trees near swamps along the Mississippi River. 



Diedrocephala versuta Say. Very abundant in central and 

 southern Missouri. Adults first observed in June. All 

 stages abroad in fields from July to November. Injurious 

 to cowpeas in Southeast Missouri. Food plants include 

 alfalfa, clover, sunflower, grasses, and many weeds. Com- 

 mon on several ornamental plants and shrubs in the 

 Missouri Botanical Gardens at St. Louis during September. 



Draeculacephala reticulata Sign. Rather common at Charles- 

 ton and Sikeston during July and August and September, 

 on corn, alfalfa and grasses. Taken at Chillicothe, Sept. 6, 

 Stanberry, Sept. 7. The last two records extend the distri- 

 bution of this jassid to north of the Missouri River, a fact 

 which is interesting in view of the distribution recorded 

 by Prof. Osborn in Bull. 108. Bur. of Ent. 



Draeculacephala angulifera Walker. Quite common on grass at 

 Charleston. 



Draeculacephala mollipes Say. Abundant throughout the state. 

 All stages present from April to November. Of great 

 economic importance. A decided pest to young grains and 

 grasses. Known to feed on an innumerable list of plants 

 and shrubs, field crops, and ornamentals. Adults migrate 

 in large numbers. About the most common jassid in 

 Missouri. 



Draeculacephala noveboracensis Fitch. Taken on grass at 

 Charleston. 



Helochara communis Fitch. Swept from wheat on many warm, 

 sunny days during the winter. In July collected from 

 alfalfa. Recorded only from Mississippi County. 



Gypona 8-lineata Say. Occurs throughout the state. Has 

 special liking for shady and damp places. Appears to be 

 essentially a grass feeder.
