 and angustipennis are usually found in orchards and similar situations. 

 (E. 4- punciatus, on the other hand, like nigricornis, is found in open 

 situations and in the vicinity of corn fii^lds, and in all probability occiu's 

 on corn. 



The species ma}^ be distinguished l)y the following synojjtical key:* 



A. Hind legs slender, and tiba- having weak spines. 



B. l*'irst two segments of antenna' with black markings Ix-neath.

 inside ben(>ath, second joint with two j)arallel lines beneath; 

 third joint of maxillary ])alpi nearly oi- (piite as long as fourth 

 and fifth united; pale yellowish; wings much longer than 

 wing-covers; wing-covers flattened above, transjiarent, and 

 very narrow; the al)domen and leg not marked with black.
