AA. Sectors of posterior wings concluded. 



CC. First and third apical cells of elytra completely sepa- 

 rated by the second oblong apical cell. 

 D. Scutellum thickened and distinctly elevated api- 



cally. Hymetta. 



DD. Scutellum not thickened and elevated apically. 



Erythroneura. 



Genus ALEBRA Fieb. 



The members of this genus are slender forms with a bluntly 

 rounded head which is narrower than the pronotum. Ocelli are 

 present. The elytra greatly exceed the abdomen, overlap at 

 the apex, and have a distinct appendix. The sectors of the 

 under wings end in a marginal vein and there are three apical 

 cells. 



One species and a variety have been taken in the state.

The following description of this species is given by De Long: 



"Rather robust, long, yellow or white in color. Length, 3.5 to 4 mm. 



"Head blunt, parallel-margined, slightly curved anteriorly. Pronotum 

 wider than head including eyes, elytra long, rather narrow. 



"Color: Male, usually bright yellow, apices of elytra fumose. Female, 

 varying, usually white, pronotum with two stripes, a broad one on suture 

 and one along costa of elytra, yellow, head and pronotum often brown." 



Distribution: The only record of this species for the state is 

 from Pottawatomie county. 



Hosts: De Long records taking specimens from willows, 

 grapevines and weeds. Crevecoeur took specimens from burr 

 oak.
