174 GLYPHIPTEKYOID.«. 



In habit all the perfect insects of this genus are true daj'- 

 fliers, flying in the sunshine from May to July; and when at 

 rest alternately raising and depressing the wings, which clia- 

 racteristic may easily be observed with T/irasoiiella, wdiich may 

 be found swarming amongst rushes everywhere in June ; fiisco- 

 vindella has the same peculiarity, though in a less degree than 

 the other species, it frequents flowery places among short grass, 

 in May and June ; the little Fischeriella shows no especial par- 

 tiality for any particular plant, but I have often observed it sit- 

 ting on the flowers of Aiitltriscus s?/Jvesiris, the white petals of 

 which served to show ofl' to advantage the nearly black wings of 

 the elegant species ; I have also observed it swarming round the 

 twigs of young fir-trees. 



None of the larvpe of this genus were known till ]\Ir. Weir 

 discovered last summer that of cquitella, feeding inside the shoots 

 of the Sednm acre ; it exhibited no peculiarity in structure; the 

 larvre of the other species still remain undiscovered.
