The only peculiar character assigned for the genus, an extra cell on 

 tegrnen basad from fourth apical cell, must be either of freakish occur- 

 rence, or the genus does not pertain to the Eupterygidae.

Proposed as a substitute for Compsus Fieber, 1866, not Compsus 

 Schoenherr, 1826, Coleoptera. Which see under Compsus 1866. 



Alebra automatically takes the genotype of Compsus, namely Cicada 

 albostriella Fallen.

 Gillette* and Van Duzeef synonymize this with Empoasca Walsh.

 Gillette considers! this a synonym of Typhlocyba Germar. European 

 authorities have kept it separate.

This genus was placed by Kirkaldy near the genus Spangbergiella, that 

 is among the Dorydiid Jassini. Melichar, 1903, locatesll it among the 

 Acocephalini. His description and figures of the venation, however, are 

 very suggestive of the Eupterygidae, where Kirkaldy locates the genus in 

 1907? in which he is followed by Oshanin, 1912.** The genus Kosasia 

 (Distant, W. L. Insecta Transvaaliensia, I, p. 240, 1910) said to be related 

 to Nirvana is not an Eupterygid, while the latter apparently is.
