ZONITIS Fabr. 



Z. bilineata Say. Madison, VIII, 5 (Pr) , Orange Mts. (Bf), Stateu Island 

 (Lg). 



MACROBASIS Lee. 



M. unicolor Kirby. Occurs throughout the State, VI, VII sometimes com- 

 monly, often on Baptisia tinctorum, not rarely on potatoes. 



EPICAUTA Redt. 



E. trichrus Pall. Westville, rare (Li), Eastern New Jersey (Dietz) ; beetle 



feeds on sweet potatoes, on wild Convolvulus and on May -weed ( Maruta 



cotula) in August ; but not common (Ch). 

 E. vittata Fabr. Throughout the State ; often destructive in late summer to 



potatoes and other garden crops or to flowers: the "old fashioned" 



potato beetle. 

 E. cinerea Forst. Throughout the State in August, with much the same 



habits as the preceding ; but not so often injurious : both of these species 



are more common north of the middle of the State. 

 E. pennsylvanica DeG. Throughout the State, late, VIII and IX, common 



on Solidago. 



POMPHOPCEA Lee. 



P. aenea Say. Woodside (Bf), Westville (Li), Anglesea (W), adult some- 

 times injurious to blossoms of fruit trees (Ch) ; in New Jersey I have 

 seen this only in isolated specimens in early spring, and it probably 

 occurs throughout the State. 



P. sayi Lee. Greenwood Lake, VI (Beyer). 



Family RHIPIPHORIDiK 



Contains wedge-shaped or clumsy, almost shapeless forms, with short, some- 

 times pointed wing-covers, beyond which the hind wings sometimes project so 

 as to cover the abdomen. The head is bent down, the antenna; are serrated 

 in the female and flabellate in the male. The adults are rare, occur on flowers, 

 and the larva' are parasitic, some in the nests of wasps, and some on cock- 

 roaches.
